## <a id="intro">1.</a> Introduction

This directory contains the sources and documentation for Tk, a
cross-platform GUI toolkit implemented with the Tcl scripting language.

For details on features, incompatibilities, and potential problems with
this release, see [the Tcl/Tk 9.1 Web page](https://www.tcl-lang.org/software/tcltk/9.1.html)
this release, see [the Tcl/Tk 9.0 Web page](https://www.tcl-lang.org/software/tcltk/9.0.html)
or refer to the "changes" file in this directory, which contains a
historical record of all changes to Tk.

Tk is maintained, enhanced, and distributed freely by the Tcl community.
Source code development and tracking of bug reports and feature requests
take place at [core.tcl-lang.org](https://core.tcl-lang.org/).
Tcl/Tk release and mailing list services are [hosted by

The source code for Tk is managed by fossil.  Tk developers coordinate all

Release Tk 9.1a0 arises from the check-in with tag `core-9.1a0`.
Release Tk 9.0.2 arises from the check-in with tag `core-9-0-2`.

Tk 9.1a0 continues the Tk 9.x series of releases.  The Tk 9.x series
do not support Tcl 8.6.  The Tk 9.1 series extends the Tcl 9.0 series.
To make use of Tk 9.1a0, first a Tcl 9.0 or 9.1 release must be present.
Tk 9.0.2 continues the Tk 9.0 series of releases.  The Tk 9.0 series
does not support Tcl 8.6.  The Tk 9.0 series extends the Tcl 9.0 series.
To make use of Tk 9.0.2, first a Tcl 9.0 release must be present.
As new Tk features are developed, expect them to appear in Tk 9, but not
necessarily in Tk 8.

Tk patch releases have the primary purpose of delivering bug fixes
to the userbase.

Release Tk 9.0.1 arises from the check-in with tag `core-9-0-1`.

Tk 9.0.1 continues the Tk 9.0 series of releases.  The Tk 9.0 series
does not support Tcl 8.6.  The Tk 9.0 series extends the Tcl 9.0 series.
To make use of Tk 9.0.1, first a Tcl 9.0 release must be present.
As new Tk features are developed, expect them to appear in Tk 9, but not
necessarily in Tk 8.

Tk patch releases have the primary purpose of delivering bug fixes
to the userbase.  As the first patch release in the Tk 9.0 series,
Tk 9.0.1 also includes a small number of interface changes that complete
some incomplete features first delivered in Tk 9.0.0.

Release Tk 9.0.0 arises from the check-in with tag `core-9-0-0`.

Highlighted differences between Tk 9.0 and Tk 8.6 are summarized below,
with focus on changes important to programmers using the Tk library and
writing Tcl scripts containing Tk commands.
# Potential incompatibilities to 9.0
 - [MS-Win: the undocumented option -xpstyle was removed from tk_chooseDirectory and tk_getOpenFile](https://core.tcl-lang.org/tk/tktview/441c52)

## Many improvements to use of platform features and conventions.

## Widget options
 - New `ttk::progressbar` option: **-text**
 - `$frame ... -backgroundimage $img -tile $bool`
 - `$menu id`, `$menu add|insert ... ?$id? ...`
 - `$image get ... -withalpha ...`
 - All indices now accept the forms **end**, **end-int**, **int+|-int**

## Improved widget appearance
 - `ttk::notebook` with nondefault tab positions

## Images
 - Partial SVG support
 - Read/write access to photo image metadata

## Known bugs
 - [Inconsistent reporting of child geometry changes to grid container](https://core.tcl-lang.org/tk/tktview/beaa8e)
 - [Inconsistency in whether widgets allow negative borderwidths](https://core.tcl-lang.org/tk/tktview/5f739d)

\fIselFgColorPtr\fR points to an XColor that describes the foreground
color to be used when drawing selected text.
\fIselItemPtr\fR points to the item that is currently selected, or
NULL if there is no item selected or if the canvas does not have the
selection.
\fIselectFirst\fR and \fIselectLast\fR give the indices of the first
and last selected characters in \fIselItemPtr\fR, as returned by the
\fIindexProc\fR for that item.
\fIanchorItemPtr\fR points to the item that currently has the selection
anchor;  this is not necessarily the same as \fIselItemPtr\fR.
\fIselectAnchor\fR is an index that identifies the anchor position
within \fIanchorItemPtr\fR.
\fIinsertBorder\fR contains a Tk_3DBorder to use when drawing the
insertion cursor;  \fIinsertWidth\fR gives the total width of the
insertion cursor in pixels, and \fIinsertBorderWidth\fR gives the
width of the raised  border around the insertion cursor.
\fIinsertWidthObj\fR and \fIinsertBorderWidthObj\fR contain the
same information, but the original Tcl_Obj * value.
\fIfocusItemPtr\fR identifies the item that currently has the input
focus, or NULL if there is no such item.
\fIgotFocus\fR is 1 if the canvas widget has the input focus and
0 otherwise.
\fIcursorOn\fR is 1 if the insertion cursor should be drawn in
\fIfocusItemPtr\fR and 0 if it should not be drawn;  this field
is toggled on and off by Tk to make the cursor blink.

.SH "WIDGET-SPECIFIC OPTIONS"
.OP \-autoseparators autoSeparators AutoSeparators
Specifies a boolean that says whether separators are automatically inserted in
the undo stack. Only meaningful when the \fB\-undo\fR option is true.
.OP \-blockcursor blockCursor BlockCursor
Specifies a boolean that says whether the blinking insertion cursor should be
drawn as a character-sized rectangular block. If false (the default) a thin
vertical line is used for the insertion cursor.
vertical line is used for the insertion cursor. For further discussion
refer to section \fBTHE INSERTION CURSOR\fR below.
.OP \-endline endLine EndLine
Specifies an integer line index representing the line of the underlying
textual data store that should be just after the last line contained in
the widget. This allows a text widget to reflect only a portion of a
larger piece of text. Instead of an integer, the empty string can be
provided to this configuration option, which will configure the widget
to end at the very last line in the textual data store.

The mark named \fBinsert\fR has special significance in text widgets. It is
defined automatically when a text widget is created and it may not be unset
with the
.QW "\fIpathName \fBmark unset\fR"
widget command. The \fBinsert\fR mark represents the position of the insertion
cursor, and the insertion cursor will automatically be drawn at this point
whenever the text widget has the input focus.
.PP
The \fB\-blockcursor\fR widget option controls the drawing of the cursor.
However, drawing the cursor as a solid blinking block is not exactly
performed as in real or emulated terminals. The character at the cursor
position is always drawn in it's foreground color, i.e. not in
"reverse video", which can lead to unwanted visual effects and even
hide the character entirely, when the cursor is in its on-state.
.SH "THE MODIFIED FLAG"
.PP
The text widget can keep track of changes to the content of the widget by
means of the modified flag. Inserting or deleting text will set this flag. The
flag can be queried, set and cleared programmatically as well. Whenever the
flag changes state a \fB<<Modified>>\fR virtual event is generated. See the
\fIpathName \fBedit modified\fR widget command for more details.

The Xcode projects refer to the toplevel tcl and tk source directories via the
the TCL_SRCROOT and TK_SRCROOT user build settings, by default these are set to
the project-relative paths '../../tcl' and '../../tk', if your source
directories are named differently, e.g. '../../tcl9.1' and '../../tk9.1', you
directories are named differently, e.g. '../../tcl9.0' and '../../tk9.0', you
need to manually change the TCL_SRCROOT and TK_SRCROOT settings by editing your
${USER}.pbxuser file (located inside the Tk.xcodeproj bundle directory) with a
text editor.

Detailed Instructions for building with macosx/GNUmakefile
----------------------------------------------------------

- To build a Tcl.framework and Tk.framework for use as subframeworks in another
framework, use the install-embedded target and set SUBFRAMEWORK=1.  Set the
DYLIB_INSTALL_DIR variable to the path which should be the install_name path of
the shared library and set the DESTDIR variable to the pathname of a staging
directory where the frameworks will be written.  The Tcl framework must be
built first.
For example, running the commands:
	make -C ../tcl9.0/macosx install-embedded SUBFRAMEWORK=1 DESTDIR=/tmp/tcltk \
	make -C ../tcl8.7/macosx install-embedded SUBFRAMEWORK=1 DESTDIR=/tmp/tcltk \
	DYLIB_INSTALL_DIR=/Library/Frameworks/Some.framework/Versions/X.Y/Frameworks/Tcl.framework
	make -C macosx install-embedded SUBFRAMEWORK=1 DESTDIR=/tmp/tcltk \
	DYLIB_INSTALL_DIR=/Library/Frameworks/Some.framework/Versions/X.Y/Frameworks/Tk.framework
will produce a Tcl.framework and a Tk.framework usable as subframeworks of
Some.framework.  The frameworks will be found in /tmp/tcltk/Frameworks/
