	* generic/tkObj.c (GetPixelsFromObjEx): [Bug 3431491]: Use a bit of

	notably on a canvas) without reinterpreting via a string.

	* unix/tkUnixEvent.c:	for <Key> events to use the keysym
	* unix/tkUnixEvent.c:	for <KeyPress> events to use the keysym
	* unix/tkUnixKey.c:	returned by XLookupString in preference to
	the one that appears in the raw X event at any level. This change
	allows binding to ISO_Level3_Shift-ed characters, composed characters,
	and similar beasts. KeyRelease events still work as they did before,
	as does Tk with input methods disabled.

10/18/96 (new features) A -menu option has been added to the toplevel
widget command, which allows a menu to operate as a menubar. On the
Macintosh, the menubar is displayed accross the top of the main monitor,
just like with other applications. Under Windows and Unix, the menu is
attached to the toplevel window. Also, changed some semantics.
Tearoff menus will now reflect changes to the menu it was
torn off from, and are deleted when the main menu is
torn off from, and are deleted when the master menu is
deleted. Tearoffs also reflect more look-and-feel of the
platforms they are running on. (SRP)

10/31/96 (bug fix) Under Windows, missing system cursors would
generate an error instead of falling through to the Tk cursor of the
same name. (SS)

2017-08-08 (bug)[28d0b8] Follow ICCCM advice on X selection protocol (donchenko)

2017-08-08 (bug)[4966ca] Scidb race in notebook tab selection (cramer)

--- Released 8.6.7, August 9, 2017 --- https://core.tcl-lang.org/tk/ for details

Changes to 8.7a1 include all changes to the 8.6 line through 8.6.7,
plus the following, which focuses on the high-level feature changes

 ****************************************************************************
 *
 *  Version 0.1.16.0
 *
 *  The ANSI C standard committee, for the C99 standard, specified the
 *  inclusion of a new standard include file called stdint.h.  This is
 *  a very useful and long desired include file which contains several
 *  very precise definitions for integer scalar types that is critically
 *  important for making several classes of applications portable
 *  including cryptography, hashing, variable length integer libraries
 *  and so on.  But for most developers its likely useful just for
 *  programming sanity.
 *
 *  The problem is that some compiler vendors chose to ignore the C99
 *  standard and some older compilers have no opportunity to be updated.
 *  Because of this situation, simply including stdint.h in your code
 *  makes it unportable.
 *
 *  So that's what this file is all about.  It's an attempt to build a
 *  single universal include file that works on as many platforms as
 *  possible to deliver what stdint.h is supposed to.  Even compilers
 *  that already come with stdint.h can use this file instead without
 *  any loss of functionality.  A few things that should be noted about
 *  this file:
 *
 *    1) It is not guaranteed to be portable and/or present an identical
 *       interface on all platforms.  The extreme variability of the
 *       ANSI C standard makes this an impossibility right from the
 *       very get go. Its really only meant to be useful for the vast
 *       majority of platforms that possess the capability of
 *       implementing usefully and precisely defined, standard sized
 *       integer scalars.  Systems which are not intrinsically 2s
 *       complement may produce invalid constants.
 *
 *    2) There is an unavoidable use of non-reserved symbols.
 *
 *    3) Other standard include files are invoked.
 *
 *    4) This file may come in conflict with future platforms that do
 *       include stdint.h.  The hope is that one or the other can be
 *       used with no real difference.
 *
 *    5) In the current version, if your platform can't represent
 *       int32_t, int16_t and int8_t, it just dumps out with a compiler
 *       error.
 *
 *    6) 64 bit integers may or may not be defined.  Test for their
 *       presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
 *       Note that this is different from the C99 specification which
 *       requires the existence of 64 bit support in the compiler.  If
 *       this is not defined for your platform, yet it is capable of
 *       dealing with 64 bits then it is because this file has not yet
 *       been extended to cover all of your system's capabilities.
 *
 *    7) (u)intptr_t may or may not be defined.  Test for its presence
 *       with the test: #ifdef PTRDIFF_MAX.  If this is not defined
 *       for your platform, then it is because this file has not yet
 *       been extended to cover all of your system's capabilities, not
 *       because its optional.
 *
 *    8) The following might not been defined even if your platform is
 *       capable of defining it:
 *
 *       WCHAR_MIN
 *       WCHAR_MAX
 *       (u)int64_t
 *       PTRDIFF_MIN
 *       PTRDIFF_MAX
 *       (u)intptr_t
 *
 *    9) The following have not been defined:
 *
 *       WINT_MIN
 *       WINT_MAX
 *
 *   10) The criteria for defining (u)int_least(*)_t isn't clear,
 *       except for systems which don't have a type that precisely
 *       defined 8, 16, or 32 bit types (which this include file does
 *       not support anyways). Default definitions have been given.
 *
 *   11) The criteria for defining (u)int_fast(*)_t isn't something I
 *       would trust to any particular compiler vendor or the ANSI C
 *       committee.  It is well known that "compatible systems" are
 *       commonly created that have very different performance
 *       characteristics from the systems they are compatible with,
 *       especially those whose vendors make both the compiler and the
 *       system.  Default definitions have been given, but its strongly
 *       recommended that users never use these definitions for any
 *       reason (they do *NOT* deliver any serious guarantee of
 *       improved performance -- not in this file, nor any vendor's
 *       stdint.h).
 *
 *   12) The following macros:
 *
 *       PRINTF_INTMAX_MODIFIER
 *       PRINTF_INT64_MODIFIER
 *       PRINTF_INT32_MODIFIER
 *       PRINTF_INT16_MODIFIER
 *       PRINTF_LEAST64_MODIFIER
 *       PRINTF_LEAST32_MODIFIER
 *       PRINTF_LEAST16_MODIFIER
 *       PRINTF_INTPTR_MODIFIER
 *
 *       are strings which have been defined as the modifiers required
 *       for the "d", "u" and "x" printf formats to correctly output
 *       (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
 *       (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
 *       PRINTF_INTPTR_MODIFIER is not defined for some systems which
 *       provide their own stdint.h.  PRINTF_INT64_MODIFIER is not
 *       defined if INT64_MAX is not defined.  These are an extension
 *       beyond what C99 specifies must be in stdint.h.
 *
 *       In addition, the following macros are defined:
 *
 *       PRINTF_INTMAX_HEX_WIDTH
 *       PRINTF_INT64_HEX_WIDTH
 *       PRINTF_INT32_HEX_WIDTH
 *       PRINTF_INT16_HEX_WIDTH
 *       PRINTF_INT8_HEX_WIDTH
 *       PRINTF_INTMAX_DEC_WIDTH
 *       PRINTF_INT64_DEC_WIDTH
 *       PRINTF_INT32_DEC_WIDTH
 *       PRINTF_INT16_DEC_WIDTH
 *       PRINTF_UINT8_DEC_WIDTH
 *       PRINTF_UINTMAX_DEC_WIDTH
 *       PRINTF_UINT64_DEC_WIDTH
 *       PRINTF_UINT32_DEC_WIDTH
 *       PRINTF_UINT16_DEC_WIDTH
 *       PRINTF_UINT8_DEC_WIDTH
 *
 *       Which specifies the maximum number of characters required to
 *       print the number of that type in either hexadecimal or decimal.
 *       These are an extension beyond what C99 specifies must be in
 *       stdint.h.
 *
 *  Compilers tested (all with 0 warnings at their highest respective
 *  settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
 *  bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
 *  .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
 *
 *  This file should be considered a work in progress.  Suggestions for
 *  improvements, especially those which increase coverage are strongly
 *  encouraged.

\fIborderWidth\fR specifies the number of pixels actually
occupied by the border.  The \fIrelief\fR argument indicates
which of several three-dimensional effects is desired:
\fBTK_RELIEF_RAISED\fR means that the interior of the rectangle should
appear raised relative to the exterior of the rectangle, and
\fBTK_RELIEF_SUNKEN\fR means that the interior should appear depressed.

\fBTk_Fill3DRectangle\fR is somewhat like \fBTk_Draw3DRectangle\fR except
that it first fills the rectangular area with the background color
(one corresponding
to the color used to create \fIborder\fR).  Then it calls
\fBTk_Draw3DRectangle\fR to draw a border just inside the outer edge of
the rectangular area.  The argument \fIrelief\fR indicates the desired

border; for \fBTk_Free3DBorder\fR the border to release is specified
with the Tk_3DBorder token for the border.
There should be exactly one call to \fBTk_Free3DBorderFromObj\fR or
\fBTk_Free3DBorder\fR for each call to \fBTk_Alloc3DBorderFromObj\fR

Note that \fBTk_ConfigureWidget\fR should be replaced with the new
\fBTcl_Obj\fR based API, \fBTk_SetOptions\fR.  The old interface is
retained for backward compatibility.
.PP
\fBTk_ConfigureWidget\fR is called to configure various aspects of a
widget, such as colors, fonts, border width, etc.
It is intended as a convenience procedure to reduce the amount
of code that must be written in individual widget managers to
handle configuration information.

.CS
typedef struct {
    int \fItype\fR;
    const char *\fIargvName\fR;
    const char *\fIdbName\fR;
    const char *\fIdbClass\fR;
    const char *\fIdefValue\fR;
    size_t \fIoffset\fR;
    int \fIoffset\fR;
    int \fIspecFlags\fR;
    const Tk_CustomOption *\fIcustomPtr\fR;
} \fBTk_ConfigSpec\fR;
.CE
The \fItype\fR field indicates what type of configuration option this is
(e.g. \fBTK_CONFIG_COLOR\fR for a color value, or \fBTK_CONFIG_INT\fR for
an integer value).  The \fItype\fR field indicates how to use the

form, such as a color if \fItype\fR is \fBTK_CONFIG_COLOR\fR or an integer
if \fItype\fR is \fBTK_CONFIG_INT\fR.  This value is then stored in the
record pointed to by \fIwidgRec\fR.  This record is assumed to
contain information relevant to the manager of the widget;  its exact
type is unknown to \fBTk_ConfigureWidget\fR.  The \fIoffset\fR field
of each \fIspecs\fR entry indicates where in \fIwidgRec\fR to store
the information about this configuration option.  You should use the
\fBoffsetof\fR macro to generate \fIoffset\fR values.  The location
indicated by \fIwidgRec\fR and \fIoffset\fR will be referred to as the
\fBTk_Offset\fR macro to generate \fIoffset\fR values (see below for
a description of \fBTk_Offset\fR).  The location indicated by
\fIwidgRec\fR and \fIoffset\fR will be referred to as the
.QW target
in the descriptions below.
.PP
The \fItype\fR field of each entry in \fIspecs\fR determines what
to do with the string value of that configuration option.  The
legal values for \fItype\fR, and the corresponding actions, are:
.TP
\fBTK_CONFIG_ACTIVE_CURSOR\fR
.
The value
must be an ASCII string identifying a cursor in a form
suitable for passing to \fBTk_GetCursor\fR.
The value is converted to a \fBTk_Cursor\fR by calling
\fBTk_GetCursor\fR and the result is stored in the target.
In addition, the resulting cursor is made the active cursor
for \fItkwin\fR by calling \fBXDefineCursor\fR.
If \fBTK_CONFIG_NULL_OK\fR is specified in \fIspecFlags\fR then the value
may be an empty string, in which case the target and \fItkwin\fR's
active cursor will be set to \fBNone\fR.
If the previous value of the target
was not \fBNone\fR, then it is freed by passing it to \fBTk_FreeCursor\fR.
.TP
\fBTK_CONFIG_ANCHOR\fR
.
The value must be an ASCII string identifying an anchor point in one of the ways
accepted by \fBTk_GetAnchor\fR.
The string is converted to a \fBTk_Anchor\fR by calling
\fBTk_GetAnchor\fR and the result is stored in the target.
.TP
\fBTK_CONFIG_BITMAP\fR
.
The value must be an ASCII string identifying a bitmap in a form
suitable for passing to \fBTk_GetBitmap\fR.  The value is converted
to a \fBPixmap\fR by calling \fBTk_GetBitmap\fR and the result
is stored in the target.
If \fBTK_CONFIG_NULL_OK\fR is specified in \fIspecFlags\fR then the value
may be an empty string, in which case the target is set to \fBNone\fR.
If the previous value of the target
was not \fBNone\fR, then it is freed by passing it to \fBTk_FreeBitmap\fR.
.TP
\fBTK_CONFIG_BOOLEAN\fR
.
The value must be an ASCII string specifying a boolean value.  Any
of the values
.QW true ,
.QW yes ,
.QW on ,
or
.QW 1 ,
or an abbreviation of one of these values, means true;
any of the values
.QW false ,
.QW no ,
.QW off ,
or
.QW 0 ,
or an abbreviation of one of these values, means false.
The target is expected to be an integer;  for true values it will
be set to 1 and for false values it will be set to 0.
.TP
\fBTK_CONFIG_BORDER\fR
.
The value must be an ASCII string identifying a border color in a form
suitable for passing to \fBTk_Get3DBorder\fR.  The value is converted
to a (\fBTk_3DBorder *\fR) by calling \fBTk_Get3DBorder\fR and the result
is stored in the target.
If \fBTK_CONFIG_NULL_OK\fR is specified in \fIspecFlags\fR then the value
may be an empty string, in which case the target will be set to NULL.
If the previous value of the target
was not NULL, then it is freed by passing it to \fBTk_Free3DBorder\fR.
.TP
\fBTK_CONFIG_CAP_STYLE\fR
.
The value must be
an ASCII string identifying a cap style in one of the ways
accepted by \fBTk_GetCapStyle\fR.
The string is converted to an integer value corresponding
to the cap style by calling
\fBTk_GetCapStyle\fR and the result is stored in the target.
.TP
\fBTK_CONFIG_COLOR\fR
.
The value must be an ASCII string identifying a color in a form
suitable for passing to \fBTk_GetColor\fR.  The value is converted
to an (\fBXColor *\fR) by calling \fBTk_GetColor\fR and the result
is stored in the target.
If \fBTK_CONFIG_NULL_OK\fR is specified in \fIspecFlags\fR then the value
may be an empty string, in which case the target will be set to \fBNone\fR.
If the previous value of the target
was not NULL, then it is freed by passing it to \fBTk_FreeColor\fR.
.TP
\fBTK_CONFIG_CURSOR\fR
.
This option is identical to \fBTK_CONFIG_ACTIVE_CURSOR\fR except
that the new cursor is not made the active one for \fItkwin\fR.
.TP
\fBTK_CONFIG_CUSTOM\fR
.
This option allows applications to define new option types.
The \fIcustomPtr\fR field of the entry points to a structure
defining the new option type.
See the section \fBCUSTOM OPTION TYPES\fR below for details.
.TP
\fBTK_CONFIG_DOUBLE\fR
.
The value must be an ASCII floating-point number in
the format accepted by \fBstrtol\fR.  The string is converted
to a \fBdouble\fR value, and the value is stored in the
target.
.TP
\fBTK_CONFIG_END\fR
.
Marks the end of the table.  The last entry in \fIspecs\fR
must have this type;  all of its other fields are ignored and it
will never match any arguments.
.TP
\fBTK_CONFIG_FONT\fR
.
The value must be an ASCII string identifying a font in a form
suitable for passing to \fBTk_GetFont\fR.  The value is converted
to a \fBTk_Font\fR by calling \fBTk_GetFont\fR and the result
is stored in the target.
If \fBTK_CONFIG_NULL_OK\fR is specified in \fIspecFlags\fR then the value
may be an empty string, in which case the target will be set to NULL.
If the previous value of the target
was not NULL, then it is freed by passing it to \fBTk_FreeFont\fR.
.TP
\fBTK_CONFIG_INT\fR
.
The value must be an ASCII integer string
in the format accepted by \fBstrtol\fR (e.g.
.QW 0
and
.QW 0x
prefixes may be used to specify octal or hexadecimal
numbers, respectively).  The string is converted to an integer
value and the integer is stored in the target.
.TP
\fBTK_CONFIG_JOIN_STYLE\fR
.
The value must be
an ASCII string identifying a join style in one of the ways
accepted by \fBTk_GetJoinStyle\fR.
The string is converted to an integer value corresponding
to the join style by calling
\fBTk_GetJoinStyle\fR and the result is stored in the target.
.TP
\fBTK_CONFIG_JUSTIFY\fR
.
The value must be
an ASCII string identifying a justification method in one of the
ways accepted by \fBTk_GetJustify\fR.
The string is converted to a \fBTk_Justify\fR by calling
\fBTk_GetJustify\fR and the result is stored in the target.
.TP
\fBTK_CONFIG_MM\fR
.
The value must specify a screen distance in one of the forms acceptable
to \fBTk_GetScreenMM\fR.
The string is converted to double-precision floating-point distance
in millimeters and the value is stored in the target.
.TP
\fBTK_CONFIG_PIXELS\fR
.
The value must specify screen units in one of the forms acceptable
to \fBTk_GetPixels\fR.
The string is converted to an integer distance in pixels and the
value is stored in the target.
.TP
\fBTK_CONFIG_RELIEF\fR
.
The value must be an ASCII string identifying a relief in a form
suitable for passing to \fBTk_GetRelief\fR.  The value is converted
to an integer relief value by calling \fBTk_GetRelief\fR and the result
is stored in the target.
.TP
\fBTK_CONFIG_STRING\fR
A copy
of the value is made by allocating memory space with
.
A copy of the value is made by allocating memory space with
\fBTcl_Alloc\fR and copying the value into the dynamically-allocated
space.  A pointer to the new string is stored in the target.
If \fBTK_CONFIG_NULL_OK\fR is specified in \fIspecFlags\fR then the value
may be an empty string, in which case the target will be set to NULL.
If the previous value of the target was not NULL, then it is
freed by passing it to \fBTcl_Free\fR.
.TP
\fBTK_CONFIG_SYNONYM\fR
.
This \fItype\fR value identifies special entries in \fIspecs\fR that
are synonyms for other entries.  If an \fIargv\fR value matches the
\fIargvName\fR of a \fBTK_CONFIG_SYNONYM\fR entry, the entry is not used
directly. Instead, \fBTk_ConfigureWidget\fR searches \fIspecs\fR
for another entry whose \fIargvName\fR is the same as the \fIdbName\fR
field in the \fBTK_CONFIG_SYNONYM\fR entry;  this new entry is used just
as if its \fIargvName\fR had matched the \fIargv\fR value.  The
synonym mechanism allows multiple \fIargv\fR values to be used for
a single configuration option, such as
.QW \-background
and
.QW \-bg .
.TP
\fBTK_CONFIG_UID\fR
.
The value is translated to a \fBTk_Uid\fR
(by passing it to \fBTk_GetUid\fR).  The resulting value
is stored in the target.
If \fBTK_CONFIG_NULL_OK\fR is specified in \fIspecFlags\fR and the value
is an empty string then the target will be set to NULL.
.TP
\fBTK_CONFIG_WINDOW\fR
.
The value must be a window path name.  It is translated to a
\fBTk_Window\fR token and the token is stored in the target.
.SH "GROUPED ENTRIES"
.PP
In some cases it is useful to generate multiple resources from
a single configuration value.  For example, a color name might
be used both to generate the background color for a widget (using

The \fIflags\fR argument passed to \fBTk_ConfigureWidget\fR is used
in conjunction with the \fIspecFlags\fR fields in the entries of \fIspecs\fR
to provide additional control over the processing of configuration
options.  These values are used in three different ways as
described below.
.PP
First, if the \fIflags\fR argument to \fBTk_ConfigureWidget\fR has
the \fBTK_CONFIG_ARGV_ONLY\fR bit set (i.e., \fIflags\fR | \fBTK_CONFIG_ARGV_ONLY\fR != 0),
the \fBTK_CONFIG_ARGV_ONLY\fR bit set
(i.e., \fIflags\fR | \fBTK_CONFIG_ARGV_ONLY\fR != 0),
then the option database and
\fIdefValue\fR fields are not used.  In this case, if an entry in
\fIspecs\fR does not match a field in \fIargv\fR then nothing happens:
the corresponding target is not modified.  This feature is useful
when the goal is to modify certain configuration options while
leaving others in their current state, such as when a \fBconfigure\fR
widget command is being processed.
.PP
Second, the \fIspecFlags\fR field of an entry in \fIspecs\fR may be used
to control the processing of that entry.  Each \fIspecFlags\fR
field may consists of an OR-ed combination of the following values:
.TP
\fBTK_CONFIG_COLOR_ONLY\fR
.
If this bit is set then the entry will only be considered if the
display for \fItkwin\fR has more than one bit plane.  If the display
is monochromatic then this \fIspecs\fR entry will be ignored.
.TP
\fBTK_CONFIG_MONO_ONLY\fR
.
If this bit is set then the entry will only be considered if the
display for \fItkwin\fR has exactly one bit plane.  If the display
is not monochromatic then this \fIspecs\fR entry will be ignored.
.TP
\fBTK_CONFIG_NULL_OK\fR
.
This bit is only relevant for some types of entries (see the
descriptions of the various entry types above).
If this bit is set, it indicates that an empty string value
for the field is acceptable and if it occurs then the
target should be set to NULL or \fBNone\fR, depending
on the type of the target.
This flag is typically used to allow a
feature to be turned off entirely, e.g. set a cursor value to
\fBNone\fR so that a window simply inherits its parent's cursor.
If this bit is not set then empty strings are processed as strings,
which generally results in an error.
.TP
\fBTK_CONFIG_DONT_SET_DEFAULT\fR
.
If this bit is one, it means that the \fIdefValue\fR field of the
entry should only be used for returning the default value in
\fBTk_ConfigureInfo\fR.
In calls to \fBTk_ConfigureWidget\fR no default will be supplied
for entries with this flag set;  it is assumed that the
caller has already supplied a default value in the target location.
This flag provides a performance optimization where it is expensive

for N different widget types, then N of the high-order bits will
be used.  Each \fIspecs\fR entry will have one of more of those
bits set in its \fIspecFlags\fR field to indicate the widget types
for which this entry is valid.  When calling \fBTk_ConfigureWidget\fR,
\fIflags\fR will have a single one of these bits set to select the
entries for the desired widget type.  For a working example of
this feature, see the code in tkButton.c.
.SH TK_OFFSET
.PP
The \fBTk_Offset\fR macro is provided as a safe way of generating
the \fIoffset\fR values for entries in Tk_ConfigSpec structures.
It takes two arguments:  the name of a type of record, and the
name of a field in that record.  It returns the byte offset of
the named field in records of the given type.
.SH TK_CONFIGUREINFO

typedef int \fBTk_ImageCreateProc\fR(

The \fIinterp\fR argument is the interpreter in which the \fBimage\fR
command was invoked, and \fIname\fR is the name for the new image,
which was either specified explicitly in the \fBimage\fR command
or generated automatically by the \fBimage\fR command.
The \fIobjc\fR and \fIobjv\fR arguments describe all the configuration

The \fImodelData\fR argument will be the same as the value
stored in \fI*modelDataPtr\fR by \fIcreateProc\fR when the
image was created.
\fIdeleteProc\fR should release any resources associated with
the image.
.SH TK_GETIMAGEMODELDATA

The procedure \fBTk_GetImageModelData\fR may be invoked to retrieve
The procedure \fBTk_GetImageMasterData\fR may be invoked to retrieve
information about an image.  For example, an image manager can use this
procedure to locate its image model data for an image.
If there exists an image named \fIname\fR
in the interpreter given by \fIinterp\fR, then \fI*typePtrPtr\fR is
filled in with type information for the image (the \fItypePtr\fR value
passed to \fBTk_CreateImageType\fR when the image type was registered)
and the return value is the ClientData value returned by the
\fIcreateProc\fR when the image was created (this is typically a
pointer to the image model data structure).  If no such image exists
then NULL is returned and NULL is stored at \fI*typePtrPtr\fR.

\fBTk_GetImageModelData\fR is synonym for \fBTk_GetImageMasterData\fR
.VE "TIP 581"
.SH "LEGACY INTERFACE SUPPORT"
.PP
In Tk 8.2 and earlier, the definition of \fBTk_ImageCreateProc\fR
was incompatibly different, with the following prototype:
.CS
typedef int \fBTk_ImageCreateProc\fR(
        Tcl_Interp *\fIinterp\fR,
        char *\fIname\fR,
        int \fIargc\fR,

        Tk_ImageType *\fItypePtr\fR,
        Tk_ImageModel \fImodel\fR,
        Tk_ImageMaster \fImodel\fR,
        ClientData *\fImodelDataPtr\fR);
.CE
Legacy programs and libraries dating from those days may still
contain code that defines extended Tk image types using the old
interface.  The Tk header file will still support this legacy
interface if the code is compiled with the macro \fBUSE_OLD_IMAGE\fR
defined.
.PP
.VS "TIP 581"
\fITk_ImageModel\fR is synonym for \fITk_ImageMaster\fR
.VE "TIP 581"
.PP
When the \fBUSE_OLD_IMAGE\fR legacy support is enabled, you may
see the routine \fBTk_InitImageArgs\fR in use.  This was a migration
tool used to create stub-enabled extensions that could be loaded
into interps containing all versions of Tk 8.1 and later.  Tk 8.5 no longer
provides this routine, but uses a macro to convert any attempted
calls of this routine into an empty comment.  Any stub-enabled

The first data structure is a Tk_ItemType; it contains
information such as the name of the type and pointers to
the standard procedures implemented by the type manager:
.PP
.CS
typedef struct Tk_ItemType {

    size_t \fIitemSize\fR;
    int \fIitemSize\fR;

.VE "8.7, TIP164"
} \fBTk_ItemType\fR;
.CE
.PP
The fields of a Tk_ItemType structure are described in more detail
later in this manual entry.
When \fBTk_CreateItemType\fR is called, its \fItypePtr\fR
argument must point to a structure with all of the fields initialized

.CE
.PP
The \fIcanvas\fR and \fIitemPtr\fR arguments have the usual meaning,
and \fIdeltaX\fR and \fIdeltaY\fR give the amounts that should be
added to each x and y coordinate within the item.
The type manager should adjust the item's coordinates and
update the bounding box in the item's header.
.SS ROTATEPROC
.VS "8.7, TIP164"
.PP
\fItypePtr\->rotateProc\fR is invoked by Tk to rotate a canvas item
during the \fBrotate\fR widget command.
The procedure must match the following prototype:
.PP
.CS
typedef void \fBTk_ItemRotateProc\fR(
        Tk_Canvas \fIcanvas\fR,
        Tk_Item *\fIitemPtr\fR,
        double \fIoriginX\fR,
        double \fIoriginY\fR,
        double \fIangleRad\fR);
.CE
.PP
The \fIcanvas\fR and \fIitemPtr\fR arguments have the usual meaning.
\fIoriginX\fR and \fIoriginY\fR specify an origin relative to which
the item is to be rotated, and \fIangleRad\fR gives the anticlockwise
rotation to be applied in radians.
The item should adjust the coordinates of its control points so that where
they used to have coordinates \fIx\fR and \fIy\fR, they will have new
coordinates \fIx\(fm\fR and \fIy\(fm\fR, where
.PP
.CS
\fIrelX\fR = \fIx\fR - \fIoriginX\fR
\fIrelY\fR = \fIy\fR - \fIoriginY\fR
\fIx\(fm\fR = \fIoriginX\fR + \fIrelX\fR \(mu cos(\fIangleRad\fR) + \fIrelY\fR \(mu sin(\fIangleRad\fR)
\fIy\(fm\fR = \fIoriginY\fR \(mi \fIrelX\fR \(mu sin(\fIangleRad\fR) + \fIrelY\fR \(mu cos(\fIangleRad\fR)
.CE
.PP
The control points for an item are not necessarily the coordinates provided to
the item when it is created (or via the \fItypePtr\->coordProc\fR), but could
instead be derived from them.
\fIrotateProc\fR must also update the bounding box in the item's header.
.PP
Item types do not need to provide a \fItypePtr\->rotateProc\fR. If the
\fItypePtr\->rotateProc\fR is NULL, the \fItypePtr\->coordProc\fR will be
used instead to retrieve and update the list of coordinates.
.VE "8.7, TIP164"
.SS INDEXPROC
.PP
\fItypePtr\->indexProc\fR is invoked by Tk to translate a string
index specification into a numerical index, for example during the
\fBindex\fR widget command.
It is only relevant for item types that support indexable text or coordinates;
\fItypePtr\->indexProc\fR may be specified as NULL for non-textual

.SH BUGS
The \fBTk_PhotoImageBlock\fR structure used to provide image data to
\fBTk_PhotoPutBlock\fR promises great flexibility in the layout of the
data (e.g. separate planes for the red, green, blue and alpha
channels).  Unfortunately, the implementation fails to hold this
promise.  The problem is that the \fIpixelSize\fR field is
(incorrectly) used to determine whether the image has an alpha channel.
Currently, if the offset for the alpha channel is greater or equal than
Currently, if the offset for the alpha channel is greater than or equal to
\fIpixelSize\fR, \fBtk_PhotoPutblock\fR assumes no alpha data is
present and makes the image fully opaque.  This means that for layouts
where the channels are separate (or any other exotic layout where
\fIpixelSize\fR has to be smaller than the alpha offset), the alpha
channel will not be read correctly.  In order to be on the safe side
if this issue will be corrected in a future release, it is strongly
recommended you always provide alpha data - even if the image has no

Display for which \fIid\fR was allocated.
.AP XID id in
Identifier of X resource (window, font, pixmap, cursor, graphics
context, or colormap) that is no longer in use.
.BE
.SH DESCRIPTION
.PP
This function is deprecated, it doesn't do anything since 2008-08-19.
The default allocator for resource identifiers provided by Xlib is very
simple-minded and does not allow resource identifiers to be re-used.
If a long-running application reaches the end of the resource id
space, it will generate an X protocol error and crash.
Tk replaces the default id allocator with its own allocator, which
allows identifiers to be reused.
In order for this to work, \fBTk_FreeXId\fR must be called to
tell the allocator about resources that have been freed.
Tk automatically calls \fBTk_FreeXId\fR whenever it frees a
resource, so if you use procedures like \fBTk_GetFont\fR,
\fBTk_GetGC\fR, and \fBTk_GetPixmap\fR then you need not call
\fBTk_FreeXId\fR.
However, if you allocate resources directly from Xlib, for example
by calling \fBXCreatePixmap\fR, then you should call \fBTk_FreeXId\fR
when you call the corresponding Xlib free procedure, such as
\fBXFreePixmap\fR.
If you do not call \fBTk_FreeXId\fR then the resource identifier will
be lost, which could cause problems if the application runs long enough
to lose all of the available identifiers.

\fBTk_GetScrollInfoObj\fR parses the arguments expected by widget
scrolling commands such as \fBxview\fR and \fByview\fR.
It receives the entire list of words that make up a widget command
and parses the words starting with \fIobjv\fR[2].
The words starting with \fIobjv\fR[2] must have one of the following forms:

Any of the \fBmoveto\fR, \fBscroll\fR, \fBunits\fR, and \fBpages\fR
keywords may be abbreviated.
If \fIobjv\fR has the \fBmoveto\fR form, \fBTK_SCROLL_MOVETO\fR
is returned as result and \fI*fractionPtr\fR is filled in with the
\fIfraction\fR argument to the command, which must be a proper real
value.
If \fIobjv\fR has the \fBscroll\fR form, \fBTK_SCROLL_PAGES\fR
or \fBTK_SCROLL_UNITS\fR is returned and \fI*stepsPtr\fR is filled
in with the \fInumber\fR value, which must be a  integer or a float,
If \fIobjv\fR has the \fBscroll\fR form, \fBTK_SCROLL_UNITS\fR
or \fBTK_SCROLL_PAGES\fR is returned and \fI*stepsPtr\fR is filled
in with the \fInumber\fR value, which must be a proper integer.
but if it is a float then it is converted to an integer, rounded away from 0.
If an error occurs in parsing the arguments, \fBTK_SCROLL_ERROR\fR
is returned and an error message is left in interpreter
\fIinterp\fR's result.

interpreter in which the option table will be used.

Note that the easiest way to learn how to use these procedures is to
look at a working example.  In Tk, the simplest example is the code
that implements the button family of widgets, which is in \fBtkButton.c\fR.
Other examples are in \fBtkSquare.c\fR and \fBtkMenu.c\fR.
.PP
In order to use these procedures, the code that implements the widget
must contain a static array of Tk_OptionSpec structures. This is a
template that describes the various options supported by that class of

class.  A Tk_OptionTable may be used only in a single interpreter, given
by the \fIinterp\fR argument to \fBTk_CreateOptionTable\fR.  When an
option table is no longer needed \fBTk_DeleteOptionTable\fR should be
called to free all of its resources.  All of the option tables
for a Tcl interpreter are freed automatically if the interpreter is deleted.

\fBTk_InitOptions\fR is invoked when a new widget is created to set the
default values for all of the widget's configuration options that do not
default values.
have \fBTK_OPTION_DONT_SET_DEFAULT\fR set in their \fIflags\fR field.
\fBTk_InitOptions\fR is passed a token for an option table
(\fIoptionTable\fR) and a pointer to a widget record (\fIrecordPtr\fR),
which is the C structure that holds information about this widget.
\fBTk_InitOptions\fR uses the information in the option table to choose an
appropriate default for each option, except those having
appropriate default for each option, then it stores the default value
\fBTK_OPTION_DONT_SET_DEFAULT\fR set, then it stores the default value
directly into the widget record, overwriting any information that was
already present in the widget record.  \fBTk_InitOptions\fR normally
returns \fBTCL_OK\fR.  If an error occurred while setting the default
values (e.g., because a default value was erroneous) then \fBTCL_ERROR\fR
is returned and an error message is left in \fIinterp\fR's result if
\fIinterp\fR is not NULL.
\fIinterp\fR is not NULL. For any widget's configuration option that
has \fBTK_OPTION_DONT_SET_DEFAULT\fR set in its \fIflags\fR field,
the above initialization is fully skipped, see below.
.PP
\fBTk_SetOptions\fR is invoked to modify configuration options based
on information specified in a Tcl command.  The command might be one that
creates a new widget, or a command that modifies options on an existing
widget.  The \fIobjc\fR and \fIobjv\fR arguments describe the
values of the arguments from the Tcl command.  \fIObjv\fR must contain
an even number of objects: the first object of each pair gives the name of

(e.g., because \fInamePtr\fR contains an unknown option name) then NULL
is returned and an error message is left in \fIinterp\fR's result unless
\fIinterp\fR is NULL.
.PP
\fBTk_FreeConfigOptions\fR must be invoked when a widget is deleted.
It frees all of the resources associated with any of the configuration
options defined in \fIrecordPtr\fR by \fIoptionTable\fR.
.PP
The \fBTk_Offset\fR macro is provided as a safe way of generating the
\fIobjOffset\fR and \fIinternalOffset\fR values for entries in
Tk_OptionSpec structures.  It takes two arguments: the name of a type
of record, and the name of a field in that record. It returns the byte
offset of the named field in records of the given type.
.SH "TEMPLATES"
.PP
The array of Tk_OptionSpec structures passed to \fBTk_CreateOptionTable\fR
via its \fItemplatePtr\fR argument describes the configuration options
supported by a particular class of widgets.  Each structure specifies
one configuration option and has the following fields:
.CS
typedef struct {
    Tk_OptionType \fItype\fR;
    const char *\fIoptionName\fR;
    const char *\fIdbName\fR;
    const char *\fIdbClass\fR;
    const char *\fIdefValue\fR;
    size_t \fIobjOffset\fR;
    size_t \fIinternalOffset\fR;
    int \fIobjOffset\fR;
    int \fIinternalOffset\fR;
    int \fIflags\fR;
    const void *\fIclientData\fR;
    int \fItypeMask\fR;
} \fBTk_OptionSpec\fR;
.CE
The \fItype\fR field indicates what kind of configuration option this is
(e.g. \fBTK_OPTION_COLOR\fR for a color value, or \fBTK_OPTION_INT\fR for

\fIdbName\fR is NULL then the option database is not used by
\fBTk_InitOptions\fR for this option.  The \fIdefValue\fR field
specifies a default value for this configuration option if no
value is specified in the option database.  The \fIobjOffset\fR and
\fIinternalOffset\fR fields indicate where to store the value of this
option in widget records (more on this below); values for the \fIobjOffset\fR
and \fIinternalOffset\fR fields should always be generated with the
\fBoffsetof\fR macro.
\fBTk_Offset\fR macro.
The \fIflags\fR field contains additional information
to control the processing of this configuration option (see below
for details).
\fIClientData\fR provides additional type-specific data needed
by certain types.  For instance, for \fBTK_OPTION_COLOR\fR types,
\fIclientData\fR is a string giving the default value to use on
monochrome displays.  See the descriptions of the different types

\fBTK_OPTION_INT\fR then the internal form is an integer.  If the
\fIobjOffset\fR or \fIinternalOffset\fR field is negative then the
value is not stored in that form.  At least one of the offsets must be
greater than or equal to zero.
.PP
The \fIflags\fR field consists of one or more bits ORed together. The
following flags are supported:
.TP
\fBTK_OPTION_NULL_OK\fR
.IP \fBTK_OPTION_NULL_OK\fR
If this bit is set for an option then an empty string will be accepted as
the value for the option and the resulting internal form will be a NULL
pointer, a zero value, or \fBNone\fR, depending on the type of the option.
If the flag is not set then empty strings will result in errors.
\fBTK_OPTION_NULL_OK\fR is typically used to allow a
feature to be turned off entirely, e.g. set a cursor value to
\fBNone\fR so that a window simply inherits its parent's cursor.
Not all option types support the \fBTK_OPTION_NULL_OK\fR
flag; for those that do, there is an explicit indication of that fact
in the descriptions below.
.TP
\fBTK_OPTION_DONT_SET_DEFAULT\fR
.IP \fBTK_OPTION_DONT_SET_DEFAULT\fR
If this bit is set for an option then no default value will be set in
\fBTk_InitOptions\fR for this option. Neither the option database, nor any
system default value, nor \fIoptionTable\fR are used to give a default
value to this option. Instead it is assumed that the caller has already
supplied a default value in the widget code.
.RS
.PP
The \fItype\fR field of each Tk_OptionSpec structure determines
how to parse the value of that configuration option. The
legal value for \fItype\fR, and the corresponding actions, are
described below.  If the type requires a \fItkwin\fR value to be
passed into procedures like \fBTk_SetOptions\fR, or if it uses
the \fIclientData\fR field of the Tk_OptionSpec, then it is indicated
explicitly; if not mentioned, the type requires neither \fItkwin\fR
nor \fIclientData\fR.
.TP
\fBTK_OPTION_ANCHOR\fR
.RE
.IP \fBTK_OPTION_ANCHOR\fR
The value must be a standard anchor position such as \fBne\fR or
\fBcenter\fR.  The internal form is a Tk_Anchor value like the ones
returned by \fBTk_GetAnchorFromObj\fR.
.TP
\fBTK_OPTION_BITMAP\fR
.IP \fBTK_OPTION_BITMAP\fR
The value must be a standard Tk bitmap name. The internal form is a
Pixmap token like the ones returned by \fBTk_AllocBitmapFromObj\fR.
This option type requires \fItkwin\fR to be supplied to procedures
such as \fBTk_SetOptions\fR, and it supports the \fBTK_OPTION_NULL_OK\fR flag.
.TP
\fBTK_OPTION_BOOLEAN\fR
.IP \fBTK_OPTION_BOOLEAN\fR
The value must be a standard boolean value such as \fBtrue\fR or
\fBno\fR.  The internal form is an integer with value 0 or 1.
\fBno\fR.  The internal form is an integer with value 0 or 1.  Note that if
.TP
\fBTK_OPTION_BORDER\fR
the \fIobjOffset\fR field is not used, information about the original

.IP \fBTK_OPTION_BORDER\fR
The value must be a standard color name such as \fBred\fR or \fB#ff8080\fR.
The internal form is a Tk_3DBorder token like the ones returned
by \fBTk_Alloc3DBorderFromObj\fR.
This option type requires \fItkwin\fR to be supplied to procedures
such as \fBTk_SetOptions\fR, and it supports the \fBTK_OPTION_NULL_OK\fR flag.
.TP
\fBTK_OPTION_COLOR\fR
.IP \fBTK_OPTION_COLOR\fR
The value must be a standard color name such as \fBred\fR or \fB#ff8080\fR.
The internal form is an (XColor *) token like the ones returned by
\fBTk_AllocColorFromObj\fR.
This option type requires \fItkwin\fR to be supplied to procedures
such as \fBTk_SetOptions\fR, and it supports the \fBTK_OPTION_NULL_OK\fR flag.
.TP
\fBTK_OPTION_CURSOR\fR
.IP \fBTK_OPTION_CURSOR\fR
The value must be a standard cursor name such as \fBcross\fR or \fB@foo\fR.
The internal form is a Tk_Cursor token like the ones returned by
\fBTk_AllocCursorFromObj\fR.
This option type requires \fItkwin\fR to be supplied to procedures
such as \fBTk_SetOptions\fR, and when the option is set the cursor
for the window is changed by calling \fBXDefineCursor\fR.  This
option type also supports the \fBTK_OPTION_NULL_OK\fR flag.

This option allows applications to define new option types.  The
clientData field of the entry points to a structure defining the new
option type.  See the section \fBCUSTOM OPTION TYPES\fR below for details.
.TP
\fBTK_OPTION_DOUBLE\fR
.IP \fBTK_OPTION_DOUBLE\fR
The string value must be a floating-point number in
the format accepted by \fBstrtol\fR.  The internal form is a C
\fBdouble\fR value.  This option type supports the \fBTK_OPTION_NULL_OK\fR
flag; if a NULL value is set, the internal representation is set to zero.
.TP
\fBTK_OPTION_END\fR
.IP \fBTK_OPTION_END\fR
Marks the end of the template.  There must be a Tk_OptionSpec structure
with \fItype\fR \fBTK_OPTION_END\fR at the end of each template.  If the
\fIclientData\fR field of this structure is not NULL, then it points to
an additional array of Tk_OptionSpec's, which is itself terminated by
another \fBTK_OPTION_END\fR entry.  Templates may be chained arbitrarily
deeply.  This feature allows common options to be shared by several
widget classes.
.TP
\fBTK_OPTION_FONT\fR
.IP \fBTK_OPTION_FONT\fR
The value must be a standard font name such as \fBTimes 16\fR.
The internal form is a Tk_Font handle like the ones returned by
\fBTk_AllocFontFromObj\fR.
This option type requires \fItkwin\fR to be supplied to procedures
such as \fBTk_SetOptions\fR, and it supports the \fBTK_OPTION_NULL_OK\fR flag.
.TP
\fBTK_OPTION_INT\fR
.IP \fBTK_OPTION_INT\fR
The string value must be an integer in the format accepted by
\fBstrtol\fR (e.g. \fB0\fR and \fB0x\fR prefixes may be used to
specify octal or hexadecimal numbers, respectively).  The internal
form is a C \fBint\fR value.

\fBTK_OPTION_JUSTIFY\fR
.IP \fBTK_OPTION_JUSTIFY\fR
The value must be a standard justification value such as \fBleft\fR.
The internal form is a Tk_Justify like the values returned by
\fBTk_GetJustifyFromObj\fR.
.TP
\fBTK_OPTION_PIXELS\fR
.IP \fBTK_OPTION_PIXELS\fR
The value must specify a screen distance such as \fB2i\fR or \fB6.4\fR.
The internal form is an integer value giving a
distance in pixels, like the values returned by
\fBTk_GetPixelsFromObj\fR.  Note: if the \fIobjOffset\fR field is not
used then information about the original value of this option will be lost.

.TP
\fBTK_OPTION_RELIEF\fR
.IP \fBTK_OPTION_RELIEF\fR
The value must be standard relief such as \fBraised\fR.
The internal form is an integer relief value such as
\fBTK_RELIEF_RAISED\fR.  This option type supports the \fBTK_OPTION_NULL_OK\fR
flag; if the empty string is specified as the value for the option,
the integer relief value is set to \fBTK_RELIEF_NULL\fR.

\fBTK_RELIEF_NULL\fR.
.TP
\fBTK_OPTION_STRING\fR
.IP \fBTK_OPTION_STRING\fR
The value may be any string.  The internal form is a (char *) pointer
that points to a dynamically allocated copy of the value.
This option type supports the \fBTK_OPTION_NULL_OK\fR flag.
.TP
\fBTK_OPTION_STRING_TABLE\fR
.IP \fBTK_OPTION_STRING_TABLE\fR
For this type, \fIclientData\fR is a pointer to an array of strings
suitable for passing to \fBTcl_GetIndexFromObj\fR.  The value must
be one of the strings in the table, or a unique abbreviation of
one of the strings.  The internal form is an integer giving the index
into the table of the matching string, like the return value
from \fBTcl_GetStringFromObj\fR.  This option type supports the
\fBTK_OPTION_NULL_OK\fR flag; if a NULL value is set, the internal
representation is set to -1.
.TP
\fBTK_OPTION_SYNONYM\fR
.IP \fBTK_OPTION_SYNONYM\fR
This type is used to provide alternative names for an option (for
example, \fB\-bg\fR is often used as a synonym for \fB\-background\fR).
The \fBclientData\fR field is a string that gives the name of another
option in the same table.  Whenever the synonym option is used, the
information from the other option will be used instead.
.TP
\fBTK_OPTION_WINDOW\fR
.IP \fBTK_OPTION_WINDOW\fR
The value must be a window path name.  The internal form is a
\fBTk_Window\fR token for the window.
This option type requires \fItkwin\fR to be supplied to procedures
such as \fBTk_SetOptions\fR (in order to identify the application),
and it supports the \fBTK_OPTION_NULL_OK\fR flag.

.PP

the original screen-independent value. Thus for \fBTK_OPTION_PIXELS\fR options
it is better to use the \fIobjOffset\fR field.  In this case the original
value of the option is retained in the object and can be returned when
the option is retrieved.  In most cases it is convenient to use the
\fIinternalOffset\fR field as well, so that the integer value is
immediately available for use in the widget code (alternatively,
\fBTk_GetPixelsFromObj\fR can be used to extract the integer value from
the object whenever it is needed).  Note: the problem of losing information
on retrievals exists only for \fBTK_OPTION_PIXELS\fR options.
the object whenever it is needed).  Note that the problem of losing
information on retrievals exists only for \fBTK_OPTION_PIXELS\fR options.
.PP
The second reason to use the \fIobjOffset\fR field is in order to
implement new types of options not supported by these procedures.
To implement a new type of option, you can use \fBTK_OPTION_STRING\fR as
the type in the Tk_OptionSpec structure and set the \fIobjOffset\fR field
but not the \fIinternalOffset\fR field.  Then, after calling
\fBTk_SetOptions\fR, convert the object to internal form yourself.
.PP
Ttk widgets do not support the \fIinternalOffset\fR machinery.
Option values of Ttk widgets are always stored as (Tcl_Obj *), meaning that
the \fIobjOffset\fR field must be used.
.SH "CUSTOM OPTION TYPES"
.PP
Applications can extend the built-in configuration types with
additional configuration types by writing procedures to parse, print,
free, and restore saved copies of the type and creating a structure
pointing to those procedures:
.CS
typedef struct Tk_ObjCustomOption {
    char *name;
    const char *\fIname\fR;
    Tk_CustomOptionSetProc *\fIsetProc\fR;
    Tk_CustomOptionGetProc *\fIgetProc\fR;
    Tk_CustomOptionRestoreProc *\fIrestoreProc\fR;
    Tk_CustomOptionFreeProc *\fIfreeProc\fR;
    ClientData \fIclientData\fR;
} \fBTk_ObjCustomOption\fR;

may be NULL, indicating that no function should be called for those
operations.
.PP
The \fIsetProc\fR procedure is invoked by \fBTk_SetOptions\fR to
convert a Tcl_Obj into an internal representation and store the
resulting value in the widget record.  The arguments are:
.RS

\fIclientData\fR
.IP \fIclientData\fR
A copy of the \fIclientData\fR field in the Tk_ObjCustomOption

.IP \fITkwin\fR
A copy of the \fItkwin\fR argument to \fBTk_SetOptions\fR
.TP
\fIvaluePtr\fR
.IP \fIvaluePtr\fR
A pointer to a reference to a Tcl_Obj describing the new value for the
option; it could have been specified explicitly in the call to
\fBTk_SetOptions\fR or it could come from the option database or a
default.  If the objOffset for the option is non-negative (the option
value is stored as a (Tcl_Obj *) in the widget record), the Tcl_Obj
pointer referenced by \fIvaluePtr\fR is the pointer that will be
stored at the objOffset for the option.  \fISetProc\fR may modify the
value if necessary; for example, \fIsetProc\fR may change the value to
NULL to support the \fBTK_OPTION_NULL_OK\fR flag.
.TP
\fIrecordPtr\fR
.IP \fIrecordPtr\fR
A pointer to the start of the widget record to modify.
.TP
\fIinternalOffset\fR

Offset in bytes from the start of the widget record to the location
where the internal representation of the option value is to be placed.

A pointer to storage allocated in a Tk_SavedOptions structure for the
internal representation of the original option value.  Before setting
the option to its new value, \fIsetProc\fR should set the value
referenced by \fIsaveInternalPtr\fR to the original value of the
option in order to support \fBTk_RestoreSavedOptions\fR.

.SH DESCRIPTION
.PP

.PP
\fBTk_Display\fR returns a pointer to the Xlib display structure
corresponding to \fItkwin\fR.  \fBTk_DisplayName\fR returns an
ASCII string identifying \fItkwin\fR's display.  \fBTk_ScreenNumber\fR
returns the index of \fItkwin\fR's screen among all the screens
of \fItkwin\fR's display.  \fBTk_Screen\fR returns a pointer to
the Xlib structure corresponding to \fItkwin\fR's screen.
\fBTk_AlwaysShowSelection\fR indicates whether text/entry widgets
should always display their selection, regardless of window focus.
.PP
\fBTk_X\fR, \fBTk_Y\fR, \fBTk_Width\fR, and \fBTk_Height\fR
return information about \fItkwin's\fR location within its
parent and its size.  The location information refers to the
upper-left pixel in the window, or its border if there is one.
The width and height information refers to the interior size
of the window, not including any border.  \fBTk_Changes\fR

information about the visual characteristics of a window.
\fBTk_Visual\fR returns the visual type for
the window, \fBTk_Depth\fR returns the number of bits per pixel,
and \fBTk_Colormap\fR returns the current
colormap for the window.  The visual characteristics are
normally set from the defaults for the window's screen, but
they may be overridden by calling \fBTk_SetWindowVisual\fR.
.PP
\fBTk_NewWindowObj\fR creates a new \fBTcl_Obj\fR from the window.

Although the \fBbindtags\fR command may be used to assign an
arbitrary set of binding tags to a window, the default binding
tags provide the following behavior:
.IP \(bu 3
If a tag is the name of an internal window the binding applies
to that window.
.IP \(bu 3
If the tag is the name of a class of widgets, such as \fBButton\fR,
the binding applies to all widgets in that class.
.IP \(bu 3
If the tag is the name of a toplevel window the binding applies
to the toplevel window and all its internal windows.
.IP \(bu 3
If the tag is the name of a class of widgets, such as \fBButton\fR,
the binding applies to all widgets in that class;
.IP \(bu 3
If \fItag\fR has the value \fBall\fR,
the binding applies to all windows in the application.
.SH "EVENT PATTERNS"
.PP
The \fIsequence\fR argument specifies a sequence of one or more
event patterns, with optional white space between the patterns.  Each
event pattern may
take one of three forms.  In the simplest case it is a single
printing ASCII character, such as \fBa\fR or \fB[\fR.  The character
may not be a space character or the character \fB<\fR.  This form of
pattern matches a \fBKey\fR event for the particular
pattern matches a \fBKeyPress\fR event for the particular
character.  The second form of pattern is longer but more general.
It has the following syntax:
.CS
\fB<\fImodifier\-modifier\-type\-detail\fB>\fR

The entire event pattern is surrounded by angle brackets.
Inside the angle brackets are zero or more modifiers, an event

The \fItype\fR field may be any of the standard X event types, with a
few extra abbreviations.  The \fItype\fR field will also accept a

Most of the above events have the same fields and behaviors as events
in the X Windowing system.  You can find more detailed descriptions of
these events in any X window programming book.  A couple of the events

value determines which direction your widget should scroll.  Positive
values should scroll up and negative values should scroll down.
.RS
.PP
Horizontal scrolling uses \fBShift-MouseWheel\fR events, with positive
\fB%D\fR \fIdelta\fR substitution indicating left scrolling and negative
right scrolling.
Only Windows and macOS Aqua typically fire \fBMouseWheel\fR and
\fBShift-MouseWheel\fR events.  On
X11 vertical scrolling is rather supported through \fBButton-4\fR and
\fBButton-5\fR events, and horizontal scrolling through \fBShift-Button-4\fR
Horizontal scrolling events may fire from
and \fBShift-Button-5\fR events.  Horizontal scrolling events may fire from
many different hardware units such as tilt wheels or touchpads.  Horizontal
scrolling can also be emulated by holding Shift and scrolling vertically.

.SS "EVENT DETAILS"
.PP
The last part of a long event specification is \fIdetail\fR.  In the
case of a \fBButton\fR or \fBButtonRelease\fR event, it is the
number of a button (1\-9).  If a button number is given, then only an
case of a \fBButtonPress\fR or \fBButtonRelease\fR event, it is the
number of a button (1\-5).  If a button number is given, then only an
event on that particular button will match;  if no button number is
given, then an event on any button will match.  Note:  giving a
specific button number is different than specifying a button modifier;
in the first case, it refers to a button being pressed or released,
while in the second it refers to some other button that is already
depressed when the matching event occurs.  If a button
number is given then \fItype\fR may be omitted:  if will default

If the event type is \fBKey\fR or \fBKeyRelease\fR, then
If the event type is \fBKeyPress\fR or \fBKeyRelease\fR, then
\fIdetail\fR may be specified in the form of an X keysym.  Keysyms

they include all the alphanumeric ASCII characters (e.g.
.QW a
is the keysym for the ASCII character
.QW a ),
plus descriptions for non-alphanumeric characters
.PQ comma "is the keysym for the comma character" ,
plus descriptions for all the non-ASCII keys on the keyboard (e.g.
.QW Shift_L
is the keysym for the left shift key, and
.QW F1
is the keysym for the F1 function key, if it exists).  The
complete list of keysyms is not presented here;  it is
available in other X documentation and may vary from system to
system.
If necessary, you can use the \fB%K\fR notation described below
to print out the keysym name for a particular key.
If a keysym \fIdetail\fR is given, then the

An unbound event is not considered to be an error.
.SH "MULTI-EVENT SEQUENCES AND IGNORED EVENTS"
.PP
When a \fIsequence\fR specified in a \fBbind\fR command contains
more than one event pattern, then its script is executed whenever
the recent events (leading up to and including the current event)
match the given sequence.  This means, for example, that if button 1 is
clicked repeatedly the sequence \fB<Double\-Button\-1>\fR will match
clicked repeatedly the sequence \fB<Double\-ButtonPress\-1>\fR will match
each button press but the first.
If extraneous events that would prevent a match occur in the middle
of an event sequence then the extraneous events are
ignored unless they are \fBKey\fR or \fBButton\fR events.
For example, \fB<Double\-Button\-1>\fR will match a sequence of
ignored unless they are \fBKeyPress\fR or \fBButtonPress\fR events.
For example, \fB<Double\-ButtonPress\-1>\fR will match a sequence of
presses of button 1, even though there will be \fBButtonRelease\fR
events (and possibly \fBMotion\fR events) between the
\fBButton\fR events.
Furthermore, a \fBKey\fR event may be preceded by any number
of other \fBKey\fR events for modifier keys without the
\fBButtonPress\fR events.
Furthermore, a \fBKeyPress\fR event may be preceded by any number
of other \fBKeyPress\fR events for modifier keys without the
modifier keys preventing a match.
For example, the event sequence \fBaB\fR will match a press of the
\fBa\fR key, a release of the \fBa\fR key, a press of the \fBShift\fR
key, and a press of the \fBb\fR key:  the press of \fBShift\fR is
ignored because it is a modifier key.
Finally, if several \fBMotion\fR events occur in a row, only
the last one is used for purposes of matching binding sequences.

.PP
The \fBtk busy\fR command provides a simple means to block mouse pointer events
from Tk widgets, while overriding the widget's cursor with a configurable busy
cursor. Note this command does not prevent keyboard events from being sent to
the widgets made busy.

\fBtk busy\fR forget .top

.\" METHOD: cget
Returns the pathname of the busy window (i.e. the transparent window
shielding the window appearing busy) created by the \fBtk busy hold\fR
command for \fIwindow\fR, or the empty string if \fIwindow\fR is not busy.
.TP
\fBtk busy cget \fIwindow\fR \fIoption\fR
\fBtk busy cget \fIwindow option\fR
.
Queries the \fBtk busy\fR command configuration options for \fIwindow\fR.
\fIWindow\fR must be the path name of a widget previously made busy by the
\fBhold\fR operation. The command returns the present value of the specified
\fIoption\fR. \fIOption\fR may have any of the values accepted by the
\fBhold\fR operation.
.\" METHOD: configure
.TP
\fBtk busy configure \fIwindow\fR ?\fIoption value\fR?...
.
Queries or modifies the \fBtk busy\fR command configuration options for

Returns the pathnames of all widgets that are currently busy. If a
\fIpattern\fR is given, only the path names of busy widgets matching
\fIpattern\fR are returned.
.\" METHOD: forget
.TP
\fBtk busy forget \fIwindow\fR ?\fIwindow\fR?...
.
Releases resources allocated by the \fBtk busy\fR command for \fIwindow\fR,
including the transparent window. User events will again be received by
\fIwindow\fR. Resources are also released when \fIwindow\fR is destroyed.
\fIWindow\fR must be the name of a widget specified in the \fBhold\fR
operation, otherwise an error is reported.
.\" METHOD: hold
.TP
\fBtk busy hold \fIwindow\fR ?\fIoption value\fR?...
.
Makes the specified \fIwindow\fR (and its descendants in the Tk window
hierarchy) appear busy. \fIWindow\fR must be a valid path name of a Tk widget.
A transparent window is put in front of the specified window. This transparent
window is mapped the next time idle tasks are processed, and the specified
window and its descendants will be blocked from user interactions. Normally
\fBupdate\fR should be called immediately afterward to insure that the hold
operation is in effect before the application starts its processing. The
command returns the pathname of the busy window that was created (i.e. the
transparent window shielding the window appearing busy). The following
configuration options are valid:

default cursor is \fBwait\fR on Windows and \fBwatch\fR on other platforms.
.RE
.\" METHOD: status
.TP
\fBtk busy status \fIwindow\fR
.
Returns the status of a widget \fIwindow\fR. If \fIwindow\fR presently can not
receive user interactions, \fB1\fR is returned, otherwise \fB0\fR.
.SH "EVENT HANDLING"
.SS BINDINGS
.PP
The event blocking feature is implemented by creating and mapping a
transparent window that completely covers the widget. When the busy window is
mapped, it invisibly shields the widget and its hierarchy from all events that
may be sent. Like Tk widgets, busy windows have widget names in the Tk window
hierarchy. This means that you can use the \fBbind\fR command to handle
events in the busy window:
.PP
.CS
\fBtk busy\fR hold .frame.canvas
bind [\fBtk busy\fR busywindow .frame.canvas] <Enter> { ... }
bind .frame.canvas_Busy <Enter> { ... }
.CE
.PP
Normally the busy window is a sibling of the widget. The name of the busy
or
window is
.QW \fIwidget\fB_Busy\fR
where \fIwidget\fR is the name of the widget to be made busy. In the previous
example, the pathname of the busy window is
.QW \fB.frame.canvas_Busy\fR .
The exception is when the widget is a toplevel widget (such as
.QW . )
where the busy window can't be made a sibling. The busy window is then a child
of the widget named
.QW \fIwidget\fB._Busy\fR
where \fIwidget\fR is the name of the toplevel widget. In the following
example, the pathname of the busy window is
.QW \fB._Busy\fR .
.PP
.CS
set busyWin [\fBtk busy\fR hold .frame.canvas]
bind $busyWin <Enter> { ... }
\fBtk busy\fR hold .
bind ._Busy <Enter> { ... }
.CE
.SS "ENTER/LEAVE EVENTS"
.PP
Mapping and unmapping busy windows generates Enter/Leave events for all
widgets they cover. Please note this if you are tracking Enter/Leave events in
widgets.
.SS "KEYBOARD EVENTS"

.PP
The above example moves the focus from .frame immediately after invoking the
\fBhold\fR so that no keyboard events will be sent to \fB.frame\fR or any of
its descendants. It also makes sure it's not possible to leave button
\fB.cancel\fR using the keyboard.

If \fIwhat\fR is \fBunits\fR, the view adjusts left or right in units
of the \fBxScrollIncrement\fR option, if it is greater than zero,
or in units of one-tenth the window's width otherwise.
If \fIwhat is \fBpages\fR then the view
adjusts in units of nine-tenths the window's width.
If \fInumber\fR is negative then information farther to the left
becomes visible; if it is positive then information farther to the right
becomes visible.
If \fIwhat\fR is \fBunits\fR, the view adjusts left or right in units
of the \fBxScrollIncrement\fR option, if it is greater than zero,
or in units of one-tenth the window's width otherwise.

The sections below describe the various types of items supported
by canvas widgets. Each item type is characterized by two things:
first, the form of the \fBcreate\fR command used to create
instances of the type; and second, a set of configuration options
