2 * Header control
3 *
4 * Copyright 1998 Eric Kohl
5 *
6 * TODO:
7 * - Imagelist support (partially).
8 * - Callback items (under construction).
9 * - Order list support.
10 * - Control specific cursors (over dividers).
11 * - Hottrack support (partially).
12 * - Custom draw support (including Notifications).
13 * - Drag and Drop support (including Notifications).
14 * - Unicode support.
15 *
16 * FIXME:
17 * - Replace DrawText32A by DrawTextEx32A(...|DT_ENDELLIPSIS) in
18 * HEADER_DrawItem.
19 * - Little flaw when drawing a bitmap on the right side of the text.
