2 * Rebar control rev 6e
3 *
4 * Copyright 1998, 1999 Eric Kohl
5 *
6 * NOTES
7 * An author is needed! Any volunteers?
8 * I will only improve this control once in a while.
9 * Eric <ekohl@abo.rhein-zeitung.de>
10 *
11 * TODO:
12 * - vertical placement
13 * - ComboBox and ComboBoxEx placement
14 * - center image
15 * - Layout code.
16 * - Display code.
17 * - Some messages.
18 * - All notifications.
19
20 * Changes Guy Albertelli <galberte@neo.lrun.com>
21 * rev 2,3,4
22 * - Implement initial version of row grouping, row separators,
23 * text and background colors. Support additional messages.
24 * Support RBBS_BREAK. Implement ERASEBKGND and improve painting.
25 * rev 5
26 * - implement support for dragging Gripper left or right in a row. Supports
27 * WM_LBUTTONDOWN, WM_LBUTTONUP, and WM_MOUSEMOVE. Also support
28 * RBS_BANDBORDERS.
29 * rev 6
30 * 1. Make drawing of rebar attempt to match pixel by pixel with MS. (6a)
31 * 2. Fix interlock between REBAR_ForceResize and REBAR_Size (AUTO_RESIZE flag) (6a)
32 * 3. Fix up some of the notifications (RBN_HEIGHTCHANGE). (6a)
33 * 4. Fix up DeleteBand by hiding child window. (6a)
34 * 5. Change how band borders are drawn and rects are invalidated. (6b)
35 * 6. Fix height of bar with only caption text. (6b)
36 * 7. RBBS_NOGRIPPER trumps RBBS_GRIPPERALWAYS (gripper hidden), but
37 * RBBS_GRIPPERALWAYS trumps RBBS_FIXEDSIZE (gripper displays). (6b)
38 * 8. New algorithim for AdjustBand:
39 * For all bands in a row: bands left to right are sized to their "cx"
40 * size (if space available). Also use max of (cxHeader+cxMinChild) and
41 * cx. (6c)
42 * 9. New alogrithim for Layout:
43 * Insert band in row if cxHeader space is available. If adjustment
44 * rect exists, then back out bands in row from last to second into
45 * separate rows till "y" adjustment rect equalled or exceeded. (6c)
46 * 10. Implement vertical drag. (6c)
47 * 11. Use DeferWindowPos to set child window position. (6c)
48 * 12. Fixup RBN_CHILDSIZE notify. The rcBand rectangle should start
49 * after the header. (6d)
50 * 13. Flags for DeferWindowPos seem to always be SWP_NOZORDER in the
51 * traces. (6d)
52 * 14. Make handling of ComboBox and ComboBoxEx the same in
53 * _MoveChildWindow. (6d)
54 * 15. Changes in phase 2 of _Layout for WinRAR example. (6e)
55 * 16. Do notify change size of children for WM_SIZE message. (6e)
56 * 17. Re-validate first band when second is added (for gripper add). (6e)
57 *
58 *
59 *
60 * Still to do:
61 * 1. default row height should be the max height of all visible bands
62 * 2. Following still not handled: RBBS_FIXEDBMP, RBBS_CHILDEDGE,
63 * RBBS_USECHEVRON
64 * 3. RBS_VARHEIGHT is assumed to always be on.
65 * 4. RBBS_HIDDEN (and the CCS_VERT + RBBS_NOVERT case) is not really
66 * supported by the following functions:
67 * _Layout (phase 2), _InternalEraseBkgnd, _InternalHitTest,
68 * _HandleLRDrag
69 * 5. _HandleLRDrag does not properly position ComboBox or ComboBoxEx
70 * children. (See code in _MoveChildWindow.)
