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

+ +

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. + + 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).

+ +

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 maninpulate 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.

+ +

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

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.

+ +

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 + + +

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 +version (but replace the version number 2.0 with 1.1).
