+FILENAME: CheckListCtrlMixin.py
+AUTHOR: Bruce Who (bruce.who.hk at gmail.com)
+DATE: 2006-02-09
+$Revision$
+DESCRIPTION:
+ This script provide a mixin for ListCtrl which add a checkbox in the first
+ column of each row. It is inspired by limodou's CheckList.py(which can be
+ got from his NewEdit) and improved:
+ - You can just use InsertStringItem() to insert new items;
+ - Once a checkbox is checked/unchecked, the corresponding item is not
+ selected;
+ - You can use SetItemData() and GetItemData();
+ - Interfaces are changed to OnCheckItem(), IsChecked(), CheckItem().
+
+ You should not set a imagelist for the ListCtrl once this mixin is used.
+
+HISTORY:
+1.3 - You can check/uncheck a group of sequential items by <Shift-click>:
+ First click(or <Shift-Click>) item1 to check/uncheck it, then
+ Shift-click item2 to check/uncheck it, and you'll find that all
+ items between item1 and item2 are check/unchecked!
+1.2 - Add ToggleItem()
+1.1 - Initial version
