42 * An author is needed! Any volunteers?
43 * I will only improve this control once in a while.
44 * Eric <ekohl@abo.rhein-zeitung.de>

46 * TODO:
47 * - vertical placement
48 * - ComboBox and ComboBoxEx placement
49 * - center image
50 * - Layout code.
51 * - Display code.
52 * - Some messages.
53 * - All notifications.
54
55 * Changes Guy Albertelli <galberte@neo.lrun.com>
56 * rev 2,3,4
57 * - Implement initial version of row grouping, row separators,
58 * text and background colors. Support additional messages.
59 * Support RBBS_BREAK. Implement ERASEBKGND and improve painting.
60 * rev 5
61 * - implement support for dragging Gripper left or right in a row. Supports
62 * WM_LBUTTONDOWN, WM_LBUTTONUP, and WM_MOUSEMOVE. Also support
63 * RBS_BANDBORDERS.
64 * rev 6
65 * - Fix or implement notifications for RBN_HEIGHTCHANGE, RBN_CHILDSIZE.
66 * - Correct styles RBBS_NOGRIPPER, RBBS_GRIPPERALWAYS, and RBBS_FIXEDSIZE.
67 * - Fix algorithm for Layout and AdjustBand.
68 *
69 * rev 7
70 * - Fix algorithm for _Layout and _AdjustBand.
71 * - Fix or implement RBN_ENDDRAG, RB_MOVEBAND, WM_SETREDRAW,
72 * WM_STYLECHANGED, RB_MINIMIZEBAND, RBBS_VARIABLEHEIGHT, RBS_VARHEIGHT,
73 * RBBS_HIDDEN, WM_NOTIFYFORMAT, NM_NCHITTEST, WM_SETREDRAW, RBS_AUTOSIZE,
74 * WM_SETFONT, RBS_BORDERS
75 * - Create structures in WM_NCCREATE
76 * - Additional performance enhancements.
77 *
78 * rev 8
79 * 1. Create array of start and end band indexes by row and use.
80 * 2. Fix problem with REBAR_Layout Phase 2b to process only if only
81 * band in row.
82 * 3. Set the Caption Font (Regular) as default font for text.
83 * 4. Delete font handle on control distruction.
84 * 5. Add UpdateWindow call in _MoveChildWindows to match repainting done
85 * by native control
86 * 6. Improve some traces.
87 * 7. Invalidate window rectangles after SetBandInfo, InsertBand, ShowBand
88 * so that repainting is correct.
89 * 8. Implement RB_MAXIMIZEBAND for the "ideal=TRUE" case.
90 * 9. Implement item custom draw notifications partially. Only done for
91 * ITEMPREPAINT and ITEMPOSTPAINT. (Used by IE4 for "Favorites" frame
92 * to draw the word "Favorites").
93 * rev 8a
94 * 10. Handle CCS_NODIVIDER and fix WS_BORDER code.
95 * 11. Fix logic error in _AdjustBands where flag was set to valid band
96 * number (0) to indicate *no* band.
97 * 12. Fix CCS_VERT errors in _ForceResize, _NCCalcSize, and _NCPaint.
98 * 13. Support some special cases of CCS_TOP (and therefore CCS_LEFT),
99 * CCS_BOTTOM (and therefore CCS_RIGHT) and CCS_NOPARENTALIGN. Not
100 * at all sure whether this is all cases.
101 * 14. Handle returned value for the RBN_CHILDSIZE notify.
102 * 15. Implement RBBS_CHILDEDGE, and set each bands "offChild" at _Layout
103 * time.
104 * 16. Fix REBARSPACE. It should depend on CCS_NODIVIDER.
105 * rev 8b
106 * 17. Fix determination of whether Gripper is needed in _ValidateBand.
107 * 18. Fix _AdjustBand processing of RBBS_FIXEDSIZE.
108 * rev 8c
109 * 19. Fix problem in _Layout when all lengths are 0.
110 * 20. If CLR_NONE specified, we will use default BtnFace color when drawing.
111 * 21. Fix test in REBAR_Layout.
112 * rev 8d
113 * 22. Add support for WM_WINDOWPOSCHANGED to save new origin of window.
114 * 23. Correct RBN_CHILDSIZE rect value for CCS_VERT rebar.
115 * 24. Do UpdateWindow only if doing redraws.
116 * rev 8e
117 * 25. Adjust setting of offChild.cx based on RBBS_CHILDEDGE.
118 *
119 *
120 * Still to do:
121 * 2. Following still not handled: RBBS_FIXEDBMP,
122 * RBBS_USECHEVRON, CCS_NORESIZE,
123 * CCS_NOMOVEX, CCS_NOMOVEY
124 * 3. Following are only partially handled:
125 * RBS_AUTOSIZE, RBBS_VARIABLEHEIGHT
126 * 5. Native uses (on each draw!!) SM_CYBORDER (or SM_CXBORDER for CCS_VERT)
127 * to set the size of the separator width (the value SEP_WIDTH_SIZE
128 * in here). Should be fixed!!
129 * 6. The following messages are not implemented:
130 * RB_BEGINDRAG, RB_DRAGMOVE, RB_ENDDRAG, RB_GETCOLORSCHEME,
131 * RB_GETDROPTARGET, RB_MAXIMIZEBAND,
132 * RB_SETCOLORSCHEME, RB_SETPALETTE, RB_SETTOOLTIPS
133 * WM_CHARTOITEM, WM_LBUTTONDBLCLK, WM_MEASUREITEM,
134 * WM_PALETTECHANGED, WM_PRINTCLIENT, WM_QUERYNEWPALETTE,
135 * WM_RBUTTONDOWN, WM_RBUTTONUP,
136 * WM_SYSCOLORCHANGE, WM_VKEYTOITEM, WM_WININICHANGE
137 * 7. The following notifications are not implemented:
138 * NM_CUSTOMDRAW, NM_RELEASEDCAPTURE
139 * RB_CHEVRONPUSHED, RBN_MINMAX
