- | Cross Browser Tree Widget 1.17 |
- |-----------------------------------------------------------------------------|
- | Created by Emil A Eklund |
- | (http://webfx.eae.net/contact.html#emil) |
- | For WebFX (http://webfx.eae.net/) |
- |-----------------------------------------------------------------------------|
- | An object based tree widget, emulating the one found in microsoft windows, |
- | with persistence using cookies. Works in IE 5+, Mozilla and konqueror 3. |

- | Dependencies: xtree.css (To set up the CSS of the tree classes) |
- |-----------------------------------------------------------------------------|
- | 2001-01-10 | Original Version Posted. |
- | 2001-03-18 | Added getSelected and get/setBehavior that can make it behave |
- | | more like windows explorer, check usage for more information. |
- | 2001-09-23 | Version 1.1 - New features included keyboard navigation (ie) |
- | | and the ability to add and remove nodes dynamically and some |
- | | other small tweaks and fixes. |
- | 2002-01-27 | Version 1.11 - Bug fixes and improved mozilla support. |
- | 2002-06-11 | Version 1.12 - Fixed a bug that prevented the indentation line |
- | | from updating correctly under some circumstances. This bug |
- | | happened when removing the last item in a subtree and items in |
- | | siblings to the remove subtree where not correctly updated. |
- | 2002-06-13 | Fixed a few minor bugs cased by the 1.12 bug-fix. |
- | 2002-08-20 | Added usePersistence flag to allow disable of cookies. |
- | 2002-10-23 | (1.14) Fixed a plus icon issue |
- | 2002-10-29 | (1.15) Last changes broke more than they fixed. This version |
- | | is based on 1.13 and fixes the bugs 1.14 fixed withou breaking |
- | | lots of other things. |
- | 2003-02-15 | The selected node can now be made visible even when the tree |
- | | control loses focus. It uses a new class declaration in the |
- | | css file '.webfx-tree-item a.selected-inactive', by default it |
- | | puts a light-gray rectangle around the selected node. |
- | 2003-03-16 | Adding target support after lots of lobbying... |
- |-----------------------------------------------------------------------------|
- | Created 2000-12-11 | All changes are in the log above. | Updated 2003-03-16 |
