23 * Rebar control rev 8a
24 *
25 * Copyright 1998, 1999 Eric Kohl
26 *
27 * NOTES
28 * An author is needed! Any volunteers?
29 * I will only improve this control once in a while.
30 * Eric <ekohl@abo.rhein-zeitung.de>
31 *
32 * TODO:
33 * - vertical placement
34 * - ComboBox and ComboBoxEx placement
35 * - center image
36 * - Layout code.
37 * - Display code.
38 * - Some messages.
39 * - All notifications.
40
41 * Changes Guy Albertelli <galberte@neo.lrun.com>
42 * rev 2,3,4
43 * - Implement initial version of row grouping, row separators,
44 * text and background colors. Support additional messages.
45 * Support RBBS_BREAK. Implement ERASEBKGND and improve painting.
46 * rev 5
47 * - implement support for dragging Gripper left or right in a row. Supports
48 * WM_LBUTTONDOWN, WM_LBUTTONUP, and WM_MOUSEMOVE. Also support
49 * RBS_BANDBORDERS.
50 * rev 6
51 * - Fix or implement notifications for RBN_HEIGHTCHANGE, RBN_CHILDSIZE.
52 * - Correct styles RBBS_NOGRIPPER, RBBS_GRIPPERALWAYS, and RBBS_FIXEDSIZE.
53 * - Fix algorithm for Layout and AdjustBand.
54 *
55 * rev 7
56 * - Fix algorithm for _Layout and _AdjustBand.
57 * - Fix or implement RBN_ENDDRAG, RB_MOVEBAND, WM_SETREDRAW,
58 * WM_STYLECHANGED, RB_MINIMIZEBAND, RBBS_VARIABLEHEIGHT, RBS_VARHEIGHT,
59 * RBBS_HIDDEN, WM_NOTIFYFORMAT, NM_NCHITTEST, WM_SETREDRAW, RBS_AUTOSIZE,
60 * WM_SETFONT, RBS_BORDERS
61 * - Create structures in WM_NCCREATE
62 * - Additional performance enhancements.
63 *
64 * rev 8
65 * 1. Create array of start and end band indexes by row and use.
66 * 2. Fix problem with REBAR_Layout Phase 2b to process only if only
67 * band in row.
68 * 3. Set the Caption Font (Regular) as default font for text.
69 * 4. Delete font handle on control distruction.
70 * 5. Add UpdateWindow call in _MoveChildWindows to match repainting done
71 * by native control
72 * 6. Improve some traces.
73 * 7. Invalidate window rectangles after SetBandInfo, InsertBand, ShowBand
74 * so that repainting is correct.
75 * 8. Implement RB_MAXIMIZEBAND for the "ideal=TRUE" case.
76 * 9. Implement item custom draw notifications partially. Only done for
77 * ITEMPREPAINT and ITEMPOSTPAINT. (Used by IE4 for "Favorites" frame
78 * to draw the word "Favorites").
79 * rev 8a
80 * 10. Handle CCS_NODIVIDER and fix WS_BORDER code.
81 * 11. Fix logic error in _AdjustBands where flag was set to valid band
82 * number (0) to indicate *no* band.
83 * 12. Fix CCS_VERT errors in _ForceResize, _NCCalcSize, and _NCPaint.
84 * 13. Support some special cases of CCS_TOP (and therefore CCS_LEFT),
85 * CCS_BOTTOM (and therefore CCS_RIGHT) and CCS_NOPARENTALIGN. Not
86 * at all sure whether this is all cases.
87 * 14. Handle returned value for the RBN_CHILDSIZE notify.
88 * 15. Implement RBBS_CHILDEDGE, and set each bands "offChild" at _Layout
89 * time.
90 * 16. Fix REBARSPACE. It should depend on CCS_NODIVIDER.
91 *
92 *
93 * Still to do:
94 * 2. Following still not handled: RBBS_FIXEDBMP,
95 * RBBS_USECHEVRON, CCS_NORESIZE,
96 * CCS_NOMOVEX, CCS_NOMOVEY
97 * 3. Following are only partially handled:
98 * RBS_AUTOSIZE, RBBS_VARIABLEHEIGHT
99 * 5. Native uses (on each draw!!) SM_CYBORDER (or SM_CXBORDER for CCS_VERT)
100 * to set the size of the separator width (the value SEP_WIDTH_SIZE
101 * in here). Should be fixed!!
102 * 6. The following messages are not implemented:
103 * RB_BEGINDRAG, RB_DRAGMOVE, RB_ENDDRAG, RB_GETCOLORSCHEME,
104 * RB_GETDROPTARGET, RB_MAXIMIZEBAND,
105 * RB_SETCOLORSCHEME, RB_SETPALETTE, RB_SETTOOLTIPS
106 * WM_CHARTOITEM, WM_LBUTTONDBLCLK, WM_MEASUREITEM,
107 * WM_PALETTECHANGED, WM_PRINTCLIENT, WM_QUERYNEWPALETTE,
108 * WM_RBUTTONDOWN, WM_RBUTTONUP,
109 * WM_SYSCOLORCHANGE, WM_VKEYTOITEM, WM_WININICHANGE
110 * 7. The following notifications are not implemented:
111 * NM_CUSTOMDRAW, NM_RELEASEDCAPTURE
112 * RB_CHEVRONPUSHED, RBN_MINMAX
