+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
