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
