What's New in TkTreeCtrl 2.2.10

TreeCtrl Configuration Options

Ignored	Comment
-doublebuffer	This option no longer has any effect but was left in to avoid incompatibilities. Instead, the amount of double-buffering is chosen depending on the platform. Modern platforms such as Mac OS X double-buffer each toplevel whereas older platforms such as Windows XP do not.

Text Element Options

New	Comment
-lmargin1	Specifies how much the first line of text should be indented.
-lmargin2	Specifies how much the 2nd or greater lines should be indented when a line of text wraps.

Mac OS X support for Tk 8.6

Tk 8.6 dropped support for the Carbon API in favor of the modern Cocoa API on Mac OS X. TkTreeCtrl was updated to build using either Carbon (Tk 8.4/8.5) or Cocoa (Tk 8.6). If you are using the back-port of the Cocoa version with Tk 8.5 you can pass the --enable-cocoa=yes configure option when configuring TkTreeCtrl.

Build Changes

Updated to TEA version 3.7 which supports the MODULE_SCOPE macro. As a result, private symbols are not exported by the treectrl shared library on platforms that support it (i.e., gcc's __visibility__("hidden")).

Bug Fixes

Fixed a crash during error processing in [item create] due to missing return statements for the -count and -height options.
Fixed a bug where all item styles would be lost when deleting the 3rd or greater column. This bug affected any item that never had a column record allocated for the 3rd or greater column (usually because no style had been assigned).
Fixed a crash in the [item span] command when specifying "all" for the item description.
The pkgIndex.tcl file correctly handles installation directories with space or bracket characters.
Removed C++ style comments and a spurious semicolon for C89 AIX compliance. [BUG 2886595]
Fixed [item sort -decreasing] not being a "stable" sort. [BUG ID 2909930]
Fixed flickering of the dragimage under Windows 7; this requires more doublebuffering than WinXP even with Aero.
Use more double-buffering on the dragimage to fix flickering/slowness (tested on Ubuntu VM).
Fixed drawing of column/row proxy lines where XOR isn't supported (i.e. MacOSX Cocoa).
Fixed the loupe (screen capture) command under Windows 7; tested on Win7 x64 (with and without Aero) and on WinXP x32.
Fixed an X server error caused by adding a bad rectangle to an XRegion while processing <Expose> events. This would show up with -doublebuffer=window while resizing the window. [BUG 3015429]

Demo Changes

The "Layout" demo uses the new Text element option -lmargin2.
Fixed an undefined-variable error when double-clicking between column headers on X11 in the "Random" demo.
Fixed the resizing of items containing child windows when the Tile theme changes in the "Big List" demo. Also added some comments.
Disabled the dynamic-appearing scrollbars under X11 where I saw some infinite looping.

What's New in TkTreeCtrl 2.2.9

TreeCtrl Command

Arguments/Result Changed	What changed
see	OLD: $T see $item NEW: $T see $item ?$column? ?-center xy? You can specify a particular column to scroll into view horizontally. The -center option will center the item/column in the window instead of performing the minimal amount of scrolling to bring it into view at the edge of the window.

Item Configuration Options

New	Comment
-wrap	When this option is true an item will be the first in a horizontal (when the treectrl option -orient=horizontal) or a vertical (when the treectrl option -orient=vertical) range of items. See the new "iMovie (Wrap)" demo.

Bug Fixes

Fixed a compile error on SunOS due to DUMP_ALLOC being defined in the system headers.
Fixed a bug that caused a panic in B_IncrementFind when calling the [see] command before the widget had displayed itself for the first time.
Fixed a library script error when attempting to drag a column header when the window was so small the items weren't visible.
Fixed two cases where the whitespace would not be properly erased when items being deleted caused scrolling.
Fixed column headers being drawn overtop of the bottom edge of window borders if the window was very short.

Demo Changes

Added the "iMovie (Wrap)" demo to demonstrate the new item option -wrap.

What's New in TkTreeCtrl 2.2.8

Bug Fixes

Fixed a bug that caused a panic in Range_ItemUnderPoint. Thanks to SF.net user 'nobody' who found the problem.
Fixed reading an uninitialized variable when calculating column header layout.

What's New in TkTreeCtrl 2.2.7

TreeCtrl Configuration Options

New	Comment
-showrootchildbuttons	Similar to -showrootlines, this boolean option controls the display of expand/collapse buttons next to child items of the root item.

Indentation change/fix

Previously with -showroot=0, -showbuttons=0, and -showrootlines=0 there was still an extra level of indentation displayed to the left of the root's children. The only way to remove all indentation from the root's children was to set -showlines=0 as well. This is no longer the case and now behaves as expected. With the new -showrootchildbuttons option it is now possible to remove all indentation from the root's children without affecting the display of buttons/lines on deeper items.

Library Script Changes

treectrl.tcl:

The <Left> and <Right> key bindings will collapse and expand the active item if -orient=vertical and -wrap={}. Otherwise the previous behavior of setting the active item to an adjacent item is used.

Bug Fixes

Fixed corruption/crash with ".t column configure -foo" with no option value if -foo is an invalid option.

What's New in TkTreeCtrl 2.2.6

Bug Fixes

Fixed ".t item bbox" returning bogus values when asking for the bounds of a column or element in a list with many items (integer overflow).
Fixed a segfault on Win64 machines when the system theme changed.
Fixed a panic on Win64 when drawing the the marquee and drag-image dotted rectangles due to a too-small struct.

What's New in TkTreeCtrl 2.2.5

Issues regarding the incompatibility of 8.4 built TkTreeCtrl working in 8.5 were resolved. The Mac OS X API issues noted for 2.2.4 remain (they relate to difficult to reconcile core drawing changes).

A Windows DLL manifest is now embedded to address native theme drawing issues.

What's New in TkTreeCtrl 2.2.4

NOTE regarding Tk version compatibility

Under Mac OSX some internal changes to Tk 8.4.15 and Tk 8.4.17 result in incompatibilities:

This version of TkTreeCtrl built for Tk 8.4.15 will work with Tk 8.4.15 and 8.4.16 only (under Mac OSX).
This version of TkTreeCtrl built for Tk 8.4.17 will work with Tk 8.4.17 only (under Mac OSX).

TreeCtrl Configuration Options

New	Comment
-columntagexpr -itemtagexpr	These boolean options can be used to turn off tag expressions in column descriptions and item descriptions. When the value of these options is false the characters (', ')', '&', '\|', '^' and '!' have no special significance when using tags in column/item descriptions. This is useful for applications which may have arbitrary tags applied to columns or items.

Bug Fixes

Fixed partially-exposed transparent photo images not being redrawn when scrolling under X11.
Fixed potential crash with Windows theme if the system theme was changed.
Fixed ".t item cget -button" always returning 0 when the value of this option wasn't auto.
Fixed a drawing issue under Mac OSX where parts of the window would not be erased properly under Tk 8.4.15+ and Tk 8.5a7+.
Fixed crashes under Mac OSX with Tk 8.4.17 and Tk 8.5.0.
Fixed an old bug caused by a MSVC compiler optimization bug that stopped items being redrawn when the only change in appearance was the expand/collapse button needing to be redrawn.

Misc Changes

Changed the item sort code to be a "stable" sort. This means that the pre-sort order of two equal items is used as a tie-breaker.

Demo Changes

Added "Increase Font Size" and "Decrease Font Size" menu commands. Also the Console font is not changed when running under Tk 8.5.

What's New in TkTreeCtrl 2.2.3

Build Changes

When building with configure on Windows the --enable-shellicon option will run configure in the shellicon/ subdirectory.
'make dist' will create the source distribution tktreectrl-VERSION.tar.gz.
'make dist-win' will create the Windows binary distribution tktreectrl-VERSION-win32.zip.

Bug Fixes

Fixed flickering when redrawing the borders with "-doublebuffer window" when the widget was resized or parts of it were exposed.
Fixed undefined reference to vsnprintf when building with the MS compiler under Windows; it should be _vsnprintf.
Fixed a symbol conflict with Python 2.5 on ELF-based systems which also defines a symbol "Ellipsis".

What's New in TkTreeCtrl 2.2.2

Column Configuration Options

New	Comment
-itemjustify	This option allows item styles to be justified separately from the image/text in the column header. If the value of this option is unspecified (the default), then item styles are justified according to the -justify option of the column.

Item Configuration Options

Usage Changed	How it changed
-button	The value of this option can now be the word auto (or any abbreviation) in which case a button is drawn only when the item has at least one child item with its item option -visible set to true.

Style Layout Changes

The element option -draw of every element type is now deprecated. Use the new style layout option -draw instead.
The new per-state style layout option -visible controls the visibility of an element. When the value of this option evaluates to false for a given state, the element consumes no space in the layout and is not displayed. If none of the elements surrounded by an element with -union layout are visible, then the element with -union layout is not displayed.

Item Descriptions

The index argument to the child and sibling modifiers can now take the form "end?-integer?".

.t item id "root child end-1" ; # get the second-to-last child of the root item

Bug Fixes

Text elements were requesting some height from the style layout when displaying an empty string. If you were depending on this behaviour, it is suggested that you set the height of the text element using the -minheight or -height style layout options.
Window elements might not be scrolled along with the rest of the list if the area needing to be redrawn due to scrolling was obscurred by other windows. This could only happen on Win32.
The ellipsis "..." in text elements is now always displayed if the text element has less space than is needed to display its string. Previously the ellipsis would disappear when there wasn't room for a single character plus the ellipsis.
Fixed a layout bug with multi-line text elements when the unsqueezed element did not require a multi-line layout but the squeezed element did.

What's New in TkTreeCtrl 2.2.1

Bug Fixes

Fixed panic with -xscrollincrement=0, -showheader=yes, no visible items and headers wider than the window.
Fixed the wrong loop variable being used when calculating onscreen columns for an item which resulted in a random crash.
Fixed a crash when invalidating a column of an item if the column wasn't the first in a span.
Fixed a leak on X11 where the clipping region was not being freed after drawing dotted rectangles.

What's New in TkTreeCtrl 2.2

TreeCtrl Configuration Options

Deprecated	What to use instead
-defaultstyle	The -itemstyle option of a column.

TreeCtrl Command

Arguments/Result Changed	What changed
contentbox	The return value is an empty string if the content area is totally obscurred by column headers, borders, and/or locked columns. Typically this will only happen if the window is too small.
selection get	Accepts 2 optional arguments to allow in-place lindex and lrange queries of the selection. For example: .t selection get 0 ; # the first selected item .t selection get end ; # the last selected item .t selection get 1 end-1 ; # every selected item except the first and last
New	Comment
bbox	Returns the bounding box of different areas of the window. For example: .t bbox will return the bounds of the window, and: .t bbox header will return the bounds of the column headers, and: .t bbox content will return the same result as the [contentbox] command, and: .t bbox left .t bbox right will return the bounds of the left-locked and right-locked columns.

Column Configuration Options

Renamed	New name
-tag	-tags
New	Comment
-lock	This option allows columns to stick to the left or right edge of the window. Locked columns can scroll vertically but not horizontally. Valid values for this option are none (the default), left or right.
-itemstyle	Specifies the name of a style to set in this column for newly-created items. This option replaces the treectrl option -defaultstyle.
-uniform	These two options operate the same as the grid geometry manager options of the same name. For example: .t column configure 0 -uniform a .t column configure 1 -uniform a will give columns 0 and 1 the same requested width, whichever is the larger of the two columns. And: .t column configure 0 -uniform a -weight 2 .t column configure 1 -uniform a will give column 0 twice the maximum of the requested widths of columns 0 and 1. And: .t column configure 0 -expand yes -weight 2 .t column configure 1 -expand yes will give column 0 twice the extra space as column 1.
-weight

Column Command

Arguments/Result Changed	What changed
column count	Takes an optional column-description argument; the result is the number of columns that match the column description. For example: .t column count visible will return the number of columns whose -visible option is true, and: .t column count {tag a^b} will return the number of columns with either tag "a" or "b", but not both.
New	Comment
column tag add	Columns can have a list of tag names. Previously only a single tag was allowed. The tail column no longer has the word "tail" as a tag, but it is still referred to by the word "tail" in column descriptions.
column tag expr
column tag names
column tag remove

Item Configuration Options

New	Comment
-tags	Tags are textual labels applied to items to group them. Tags do not affect the appearance or behaviour of items. Tags can be used in item descriptions to operate on multiple items. More information can be found in the man page.

Item Command

Arguments/Result Changed	What changed
item count	Takes an optional item-description argument; the result is the number of items that match the item description. For example: .t item count visible will return the number of items that are displayed (i.e., those whose ancestors are all expanded, -visible options are true, etc), and: .t item count {tag a^b} will return the number of items with either tag "a" or "b", but not both.
item create	New option -tags specifies an initial list of tags for created items.
item id	Returns a list of item ids if the item description matches multiple items. For example: .t item id all will return a list of ids for all items, and: .t item id "$item children" will return the ids of every child of an item.
New	Comment
item descendants	Returns the ids of the children, grandchildren, etc of an item.
item enabled	Gets and sets the enabled state for items. All items are enabled when first created. Disabled items cannot be selected, and are ignored by the default key-navigation and mouse bindings.
item tag add	Add tags to items. For example: .t item tag add all {a b c} will add tags "a", "b" and "c" to every item.
item tag expr	Evaluate a tag expression against items. For example: .t item tag expr $item a returns 1 if an item has tag "a". Also: .t item tag expr $item a\|\|b returns 1 if an item has tag "a" or "b".
item tag names	Return a list of tag names assigned to items. For example: .t item tag names $item returns the tag list for an item, and: .t item tag names all returns every tag assigned to any item.
item tag remove	Remove tags from items. For example: .t item tag remove all {b c} will remove tags "b" and "c" from any items that have them.

Text Element

The new option -underline draws an underline under a single character of the displayed text.

Window Element

Window elements can now be properly clipped so they don't draw over the column header, borders, or outside the bounds of the item columns they occupy. This is accomplished by making the window you want to display a child of a borderless frame widget, and setting the new -clip option of the window element to TRUE. So if your program displays a canvas widget in a window element, you would change this code:

set canvas [canvas .t.canvas ...]
.t item element configure $item $column myElement -window $canvas

to this:

set frame [frame .t.clip -borderwidth 0]
set canvas [canvas $frame.canvas ...]
.t item element configure $item $column myElement -window $frame -clip yes

The -clip option tells the window element to manage the geometry of both the -window widget (i.e, the frame) and its first child widget (i.e., the canvas). In this case, the frame widget is kept sized and positioned so that it is never out-of-bounds. You can see this in the "Big List" and "Firefox Privacy" demos.

Item Descriptions

New keywords were added to allow multiple items to be specified by an item description:

The keyword list specifies a list of other item descriptions:
```
.t item id "list [list $a $b $c]"
```
The keyword range operates like the item range command:
```
.t item id "range $first $last"
```

New modifiers were added to match multiple items:

The modifier ancestors operates like the item ancestors command:
```
.t item id "$item ancestors"
```
The modifier children operates like the item children command:
```
.t item id "$item children"
```
The modifier descendants operates like the item descendants command:
```
.t item id "$item descendants"
```

New qualifiers were added to refine which items are matched:

The qualifier depth matches items at a given depth in the heirarchy:

.t item id "all depth 2" ; # find all items that are children of the root's children
.t item id "depth 2" ; # ditto

The qualifier !visible matches items that are not displayed:

.t item id "first !visible" ; # find the first item that is not displayed

The qualifier state matches items that have certain states set (or not set if '!' is used):

.t item id "first state {selected !open}" ; # find the first item that is selected and collapsed

The qualifier tag matches items that meet a tag expression:

.t item id "$item children tag {a && !b}" ; # find children of $item that have tag "a" but not tag "b"

The keyword all may now be followed by a list of qualifiers. For example:

.t item id "all !visible state myState" ; # find every item that is not displayed with user-defined state "myState"

A list of qualifiers may be used as the first part of an item description. This gives the same result as "all" followed by the qualifiers. For example:

.t item id "!visible state myState" ; # same as the previous example

Column Descriptions

New keywords list and range can be used to match multiple columns.
New qualifiers state, tag, !tail and !visible can be used to restrict which columns are specified.
The keyword all may be followed by a list of qualifiers.
A list of qualifiers may used as the first part of a column description. This gives the same result as "all" followed by the qualifiers.

Multi-item and multi-column commands

Many commands can now operate on multiple items and/or columns by using the improved item descriptions and column descriptions mentioned above. For example:

.t column configure "range 1 10" -tags {a b c}
.t column delete "tag a"
.t column id "tag {a || b}"
.t item configure "depth 1" -button yes
.t item count visible
.t item element configure "root children" all elem1 -text "Hello"
.t item id "visible"
.t item image all all image1
.t item style map "tag {a && !b}" "tag c" style2 {style1.elem1 style2.elem2}
.t item style set all all style1
.t item state forcolumn all all state1
.t item state set "tag current" ~mouseover
.t item remove "state selected"
.t item span "range 1 10" "range 10 last" 2
.t item text "root children" all "Hello"

Demo Changes

New demo "My Computer". Demonstrates disabled items used as headers.
New demo "Column Locking". Demonstrates columns that do not scroll horizontally.
The "Big List" and "Firefox Privacy" demos were changed to use the new -clip option of window elements.

Misc Changes

The tail column header will not be drawn if the tail column's -visible option is false. This can look nicer with some themes.
The -itembackground colors for a column are now extended below any items in the simplest (and most typical) case where the treectrl's -orient option is vertical and -wrap option is unspecified. The height of the rows is determined by the -itemheight or -minitemheight options; if neither of those options is specified, then -itembackground colors are not drawn below the items.
If -itembackground colors are specified for the tail column, then they are drawn.
Memory usage is improved, especially for text elements.

Bug Fixes

item create: Fixed bug where -nextsibling and -prevsibling options could specify an orphan item.
item delete: Stopped items possibly being double-deleted by nested calls through <Selection> and <ItemDelete> binding scripts.
item expand, item collapse, item toggle: Only operate on items which exist when the command is called, not any that might get created by <Expand> or <Collapse> binding scripts.
Fixed a crash and a redisplay problem when a master element was configured with a -textvariable and the associated variable changed.
When a style with window elements spanned more than one column, the window might be improperly sized during display updates.
Windows in window elements would not always be unmapped if columns or items were hidden, or if the span of an item-column changed.
The disclosure triangles (i.e., the item buttons) are drawn without a white background under OSX.

What's New in TkTreeCtrl 2.1.1

Column Command

Arguments/Result Changed	What changed
column delete	Added an optional second argument allowing a range of columns to be deleted.

Bug Fixes

The item sort command will be much faster in many cases. There was a silly error in the pivot-finding code of quicksort which resulted in the slow-down.
A column header will be redisplayed if an image in the header is altered.
Fixed bus errors on some Unix systems due to alignment problems.

Other Changes

The Tk caret is now positioned over the active item when it changes. The Tk caret is used for the Magnifier accessibility application and IME on Windows, as well as XIM under Unix.
Improved the appearance of the column headers under OSX.
Added <MouseWheel> support to OSX.
Changing the -visible option of an item could be slow if any items were selected. That is because non-visible items may not be part of the selection. A change was made so that changes to the selection caused by modifying the -visible option of an item do not occur until the next display update.

Demo Changes

New demo "Column Spanning". Demonstrates a 100-column list where styles span from 1 to 20 columns each.
The loupe command (which performs screen capture to an image) is now implemented on Windows and OSX thanks to Jeff Hobbs.
The screen-magnifier image now resizes with the "loupe" window.

What's New in TkTreeCtrl 2.1

This version should be backwards compatible with 2.0, except for a few obscure changes.

TreeCtrl Configuration Options

New	Comment
-itemwidth
-itemwidthequal	Deprecates the column -widthhack option.
-itemwidthmultiple	Deprecates the column -stepwidth option.

Column Configuration Options

Deprecated	What to use instead
-stepwidth	treectrl's -itemwidthmultiple option
-widthhack	treectrl's -itemwidthequal option

Element Command

New	Comment
element perstate	Like [item element perstate].

Item Configuration Options

New	Comment
-height	Overrides the treectrl's -itemheight option

Item Command

Deprecated	What to use instead
item element actual	item element perstate
item complex	item element configure
Behaviour Changed	What changed
item bbox	No longer returns an error if no style had been assigned to the column.
item state forcolumn	No longer returns an error if no style had been assigned to the column.
item style set	Does nothing when replacing a style with the same style. Previously the old style was freed before assigning the new style, losing the element config info if the old and new styles were the same. Potential incompatibility
Arguments/Result Changed	What changed
item create	Added options: -count -height, -nextsibling, -open, -parent, -prevsibling, and -returnid. Multiple items may be created with one call using the -count option.
item element configure	Multiple elements in multiple columns may be configured with a single call. Use '+' to separate elements, and ',' to separate columns. See the docs.
item style set	When no column is specified, returns a list of one style name per column. Previously, the list would have less values than the number of columns if no styles had ever been assigned to the rightmost column(s). Potential incompatibility
item text	When no column is specified, returns a list of one string per column.
New	Comment
item image	Partner to the [item text] command.
item element perstate	Not really new, just renamed from [item element actual] to better describe what it does. Accepts a new optional argument which specifies the state to use when determining the value of the per-state option. The following options no longer return a default value if the per-state option itself does not have a value specified: bitmap -foreground, -background border -relief text -fill, -font Potential incompatibility
item span	A style may now be displayed over multiple adjacent columns.

Notify Command

New	Comment
notify unbind	Let's you unbind all scripts from an object with one call.

Style Layout Changes

Column justification will now affect the position of elements in 2 situations which previously had no effect (Potential incompatibility):

If a -detach element had a fixed width larger than the other elements.
If an element had -iexpand x specified as well as -maxwidth, leaving some space available.

Element Changes

Bitmap, image and text elements are drawn clipped if given less space than they need.
Fixed line wrapping of text elements. It did not work for single lines of text at all (Potential incompatibility).
The text -wrap option can now be none to disable line wrapping.

Event Changes

The new static event <ItemVisibility> is generated when items become visible on screen and when items are no longer visible on screen. This event allows you to create really big lists by only assigning styles when items are about to be displayed. See the EVENTS AND SCRIPT SUBSTITUTIONS section in the help file, and the new demo "Big List".

Other Changes

On WinXP, the column header sort arrow is drawn like Explorer draws it if -usetheme is true.

Demo Changes

New demo "Big List". Demonstrates the new <ItemVisibility> event, using <Expand-before> to add items on demand, and column spanning.
The context menu has a Span submenu that lets you manipulate column spanning in items. See the item span command in the help file.
Under WinXP, the "Explorer" demos will use the new shellicon extension if available. This extension allows a treectrl to display file/folder icons using the Win32 Shell API. It may work on other versions of Windows but it hasn't been tested.

What's New in TkTreeCtrl 2.0

TreeCtrl Configuration Options

Replaced	What to use instead
-openbuttonimage	-buttonimage
-closedbuttonimage	-buttonimage
-openbuttonbitmap	-buttonbitmap
-closedbuttonbitmap	-buttonbitmap
Usage Changed	How it changed
-backgroundmode	The values "index" and "visindex" are deprecated. The value "order" should be used instead of "index", and "ordervisible" should be used instead of "visindex". This brings agreement with the new "item order" command which replaces the "item index" command.
-treecolumn	This used to be any integer value which may or may not have corresponded to an actual column. Now the value must be a valid column description, or an empty string to indicate no column should display buttons/lines.
New
-backgroundimage
-columnprefix
-columnresizemode
-itemprefix
-minitemheight
-usetheme

item range	replaces "range"

Notify Command

Arguments/Result Changed	What changed
notify generate	Added optional percentsCommand argument
notify install	Old syntax (supported but deprecated): notify install event eventName notify install detail eventName detail New syntax: notify install <eventName> notify install <eventName-detail>
notify linkage	Old syntax (supported but deprecated): notify linkage eventName notify linkage eventName detail New syntax: notify linkage <eventName> notify linkage <eventName-detail>
notify uninstall	see notify install above

Style Layout Options

Usage Changed	How it changed
-iexpand	Two new flags "x' and "y" are allowed. Previously, only the -ipadx and -ipady padding could be expanded by this option. The new xy flags expand the display area of the element, not the padding. To update your code, you will probably want to change this: $T style layout $S $E -iexpand we to this: $T style layout $S $E -iexpand x Keep in mind that -union elements are not affected by -iexpand xy, since the size of a -union element is determined by the elements it surrounds.
New
-height
-maxheight
-maxwidth
-minheight
-minwidth
-sticky
-width

Element Changes

A new element type window was added. See the new demo "Firefox Privacy" and the ELEMENTS section in the help file.
All element types have a new per-state boolean option called -draw.
The text element type has a new option called -textvariable. See the new demo "Textvariable" and the ELEMENTS section in the help file.

Event Changes

2 new %-substitution characters %P and %? are allowed in binding scripts. See the EVENTS AND SCRIPT SUBSTITUTIONS section in the help file.
The new static event <ItemDelete> is generated when items are deleted. See the EVENTS AND SCRIPT SUBSTITUTIONS section in the help file.

Library Script Changes

filelist-bindings.tcl:

The Priv(edit) variable, which is used to specify which text elements may be edited, now has the same format as Priv(sensitive). Previously only elements in the first column could be edited.
3 new commands in the TreeCtrl namespace should be used to access the Priv(dragimage), Priv(edit) and Priv(sensitive) variables. The commands are SetDragImage, SetEditable and SetSensitive.
Two new dynamic events <Edit-begin> and <Edit-end> are generated when editing a file name.

treectrl.tcl:

On OSX/Aqua, the Command key is used to perform discontinuous selection. Previously the Control key was used but Command is specified by Apple's user-interface guidelines.

Other Changes

On WinXP, the column headers and open/close buttons are drawn using the system theme if -usetheme is true. The sort arrow is drawn the old-fashioned way.
On OSX/Aqua, the column headers and open/close buttons are drawn using the system theme if -usetheme is true. The sort arrow will be drawn by the Appearance Manager as well. This will override the -arrowside and -arrowgravity options.
Columns can be moved by drag-and-drop. See column dragconfigure in the help file.
Columns can be specified in new ways. See the COLUMN DESCRIPTION section in the help file.
Added new section DYNAMIC EVENTS to the help file.
Added new section PER-STATE OPTIONS to the help file.
The new style layout option -indent allows elements to be displayed in the button/line area. See the style layout command in the help file and the new demo "Firefox Privacy".
The new item description end is equivalent to last.
If you have version 1.1 installed, replace the old pkgIndex.tcl file with the one from this version (but replace the version number 2.0 with 1.1). Otherwise the old pkgIndex.tcl file will set the TREECTRL_LIBRARY variable which will override where the library scripts are found.

Demo Changes

New demo "Firefox Privacy". Demonstrates the new window element type and -indent style layout option.
New demo "Textvariable". Demonstrates the new -textvariable option of the text element.
Added a new Event Browser window to display events generated by the main treectrl widget.
The context menu can be popped up in all the demo lists. A <Control-ButtonPress-1> binding for this was added under OSX/Aqua.
In the "Explorer" demos, the file name is hidden while editing the file name.
