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

	* 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.

\fIwidth\fR and \fIheight\fR are the dimensions of the window), and
\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_RELIEF_GROOVE\fR and \fBTK_RELIEF_RIDGE\fR mean that there should appear to be
a groove or ridge around the exterior of the rectangle.
\fBTK_RELIEF_GROOVE\fR and \fBTK_RELIEF_RIDGE\fR mean that there should

.PP
\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

with the window and color name used to create the
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
or \fBTk_Get3DBorder\fR.

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

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
.PP
The \fBTk_ConfigureInfo\fR procedure may be used to obtain
information about one or all of the options for a given widget.

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

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.

.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,

        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

\fITk_ImageModel\fR is synonym for \fITk_ImageMaster\fR
.VE "TIP 581"

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 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

\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

.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.

When fewer than 16 bits are provided for each color, they represent
the most significant bits of the color, while the lower unfilled

.SH ARGUMENTS
.AS Tk_SavedOptions "*const objv[]" in/out
.AP Tcl_Interp *interp in
A Tcl interpreter.  Most procedures use this only for returning error
messages; if it is NULL then no error messages are returned.  For
\fBTk_CreateOptionTable\fR the value cannot be NULL; it gives the
interpreter in which the option table will be used.
.AP "const Tk_OptionSpec" *templatePtr in
Points to an array of static information that describes the configuration
options that are supported.  Used to build a Tk_OptionTable.  The information
pointed to by this argument must exist for the lifetime of the Tk_OptionTable.
.AP Tk_OptionTable optionTable in
Token for an option table.  Must have been returned by a previous call
to \fBTk_CreateOptionTable\fR.
.AP void *recordPtr in/out
.AP char *recordPtr in/out
Points to structure in which values of configuration options are stored;
fields of this record are modified by procedures such as \fBTk_SetOptions\fR
and read by procedures such as \fBTk_GetOptionValue\fR.
.AP Tk_Window tkwin in
For options such as \fBTK_OPTION_COLOR\fR, this argument indicates
the window in which the option will be used.  If \fIoptionTable\fR uses
no window-dependent options, then a NULL value may be supplied for

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 \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

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

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

\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.

it is better to use the \fIobjOffset\fR field.  In this case the original

immediately available for use in the widget code (alternatively,
\fBTk_GetPixelsFromObj\fR can be used to extract the integer value from

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.

.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:

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

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
to \fBButton\fR.  For example, the specifier \fB<1>\fR

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
are textual specifications for particular keys on the keyboard;
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.

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.

.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.

command may be used to invoke various
operations on the widget. It has the following general form:
.CS
\fIpathName option \fR?\fIarg ...\fR?
\fIpathName option \fR?\fIarg arg ...\fR?
.CE
\fIOption\fR and the \fIarg\fRs

.TP
\fIpathName \fBaddtag \fItag searchSpec \fR?\fIarg ...\fR?
\fIpathName \fBaddtag \fItag searchSpec \fR?\fIarg arg ...\fR?
.
For each item that meets the constraints specified by
\fIsearchSpec\fR and the \fIarg\fRs, add
\fItag\fR to the list of tags associated with the item if it
is not already present on that list.
It is possible that no items will satisfy the constraints

Note: the insertion cursor is only displayed in an item if
that item currently has the keyboard focus (see the \fBfocus\fR widget
command, above), but the cursor position may
be set even when the item does not have the focus.
This command returns an empty string.
.TP
\fIpathName \fBimage \fIimagename\fR ?\fIsubsample\fR? ?\fIzoom\fR?
.
Draw the canvas into the Tk photo image named \fIimagename\fR. If a \fB-scrollregion\fR
has been defined then this will be the boundaries of the canvas region drawn and the
final size of the photo image. Otherwise the widget width and height with an origin
of 0,0 will be the size of the canvas region drawn and the final size of the photo
image. Optionally an integer \fIsubsample\fR factor may be given and the photo image
will be reduced in size. In addition to the \fIsubsample\fR an integer \fIzoom\fR
factor can also be given and the photo image will be enlarged. The image background
will be filled with the canvas background colour. The canvas widget does not need to
be mapped for this widget command to work, but at least one of it's ancestors must be
mapped.
This command returns an empty string.
.TP
\fIpathName \fBimove \fItagOrId index x y\fR
.
.VS 8.6
This command causes the \fIindex\fR'th coordinate of each of the items
indicated by \fItagOrId\fR to be relocated to the location (\fIx\fR,\fIy\fR).

described in \fBINDICES\fR above. Out of the standard set of items, only line
and polygon items may have their coordinates relocated this way.

Move the items given by \fItagOrId\fR in the canvas coordinate
space so that the first coordinate pair (the upper-left corner of the
bounding box) of the first item (the lowest in the display list) with
tag \fItagOrId\fR is located at
position (\fIxPos\fR,\fIyPos\fR). \fIxPos\fR and \fIyPos\fR may be

to a file and an empty string is returned; otherwise the Postscript
is returned as the result of the command.

Note: this command has no effect on window items. Window items always

This command causes the text or coordinates between \fIfirst\fR and \fIlast\fR
for each of the items indicated by \fItagOrId\fR to be replaced by
\fIstring\fR. Each item interprets \fIfirst\fR and \fIlast\fR independently
according to the rules described in \fBINDICES\fR above. Out of the standard
set of items, text items support this operation by altering their text as
directed, and line and polygon items support this operation by altering their
coordinate list (in which case \fIstring\fR should be a list of coordinates to
use as a replacement). The other items ignore this operation.

.SH "STANDARD ITEM TYPES"
.SS "ARC ITEMS"

Items of type \fBarc\fR appear on the display as arc-shaped regions.
An arc is a section of an oval delimited by two angles (specified

by the \fB\-start\fR and \fB\-extent\fR options) and displayed in
one of several ways (specified by the \fB\-style\fR option).
Arcs are created with widget commands of the following form:
.CS
\fIpathName \fBcreate arc \fIx1 y1 x2 y2 \fR?\fIoption value ...\fR?
\fIpathName \fBcreate arc \fIcoordList\fR ?\fIoption value ...\fR?
.CE
The arguments \fIx1\fR, \fIy1\fR, \fIx2\fR, and \fIy2\fR or \fIcoordList\fR give
the coordinates of two diagonally opposite corners of a
rectangular region enclosing the oval that defines the arc (except when
rectangular region enclosing the oval that defines the arc.
\fB\-height\fR is specified - see below).

After the coordinates there may be any number of \fIoption\fR\-\fIvalue\fR
pairs, each of which sets one of the configuration options
for the item. These same \fIoption\fR\-\fIvalue\fR pairs may be
used in \fBitemconfigure\fR widget commands to change the item's
configuration. An arc item becomes the current item when the mouse pointer is
over any part that is painted or (when fully transparent) that would be
painted if both the \fB\-fill\fR and \fB\-outline\fR options were non-empty.

modulo 360 is used as the extent.

arc.
\fIDegrees\fR is given in units of degrees measured counter-clockwise
from the 3-o'clock position; it may be either positive or negative.
.TP
\fB\-height \fIdistance\fR
Provides a shortcut for creating a circular arc segment by defining the
distance of the mid-point of the arc from its chord. When this option
