12 * Rebar control rev 7f
13 *
14 * Copyright 1998, 1999 Eric Kohl
15 *
16 * NOTES
17 * An author is needed! Any volunteers?
18 * I will only improve this control once in a while.
19 * Eric <ekohl@abo.rhein-zeitung.de>
20 *
21 * TODO:
22 * - vertical placement
23 * - ComboBox and ComboBoxEx placement
24 * - center image
25 * - Layout code.
26 * - Display code.
27 * - Some messages.
28 * - All notifications.
29
30 * Changes Guy Albertelli <galberte@neo.lrun.com>
31 * rev 2,3,4
32 * - Implement initial version of row grouping, row separators,
33 * text and background colors. Support additional messages.
34 * Support RBBS_BREAK. Implement ERASEBKGND and improve painting.
35 * rev 5
36 * - implement support for dragging Gripper left or right in a row. Supports
37 * WM_LBUTTONDOWN, WM_LBUTTONUP, and WM_MOUSEMOVE. Also support
38 * RBS_BANDBORDERS.
39 * rev 6
40 * - Fix or implement notifications for RBN_HEIGHTCHANGE, RBN_CHILDSIZE.
41 * - Correct styles RBBS_NOGRIPPER, RBBS_GRIPPERALWAYS, and RBBS_FIXEDSIZE.
42 * - Fix algorithm for Layout and AdjustBand.
43 *
44 * rev 7
45 * 1. Redesign _Layout to better emulate native.
46 * a. Flag rebar when a band needs to be (and all bands) need to
47 * go through rest of _Layout
48 * 2. Fix RBN_ENDDRAG contents.
49 * 3. REBAR_ForceResize changed to handle shrink of client.
50 * rev 7b
51 * 4. Support RBBS_HIDDEN in _Layout (phase 2 & 3), _InternalEraseBkgnd,
52 * and _InternalHitTest
53 * 5. Support RBS_VARHEIGHT.
54 * 6. Rewrite _AdjustBands with new algorithm.
55 * rev 7c
56 * 7. Format mask and style with labels.
57 * 8. Move calls to _ForceResize and _MoveChildWindows into _Layout to
58 * centralize processing.
59 * 9. Pass "infoPtr" to all routines instead of "hwnd" to eliminate extra
60 * calls to GetWindowLongA.
61 * 10. Use _MoveChildWindows in _HandleLRDrag.
62 * 11. Another rewrite of _AdjustBands with new algorithm.
63 * 12. Correct drawing of rebar borders and handling of RBS_BORDERS.
64 * rev 7d
65 * 13. Support WM_NOTIFYFORMAT (both incoming and outgoing) and do
66 * WM_NOTIFY correctly based on results.
67 * 14. Implement WM_SETREDRAW.
68 * 15. Native WM_ERASEBKGND draws horz and vert separators between bands and
69 * rows, and fills in the background color for each band. The gripper,
70 * image, and text for each band is drawn by the WM_PAINT process. Change
71 * this code to match.
72 * rev 7e
73 * 16. RBBS_FIXEDSIZE should not affect _AdjustBands. (Found by Mike McCormack
74 * in WinZip - Thanks!)
75 * 17. Implement WM_NCCREATE to set necessary additional styles and move most
76 * of creation stuff to it like native control.
77 * 18. WM_SETFONT should redraw only if LOWORD is TRUE.
78 * 19. Implement WM_NCHITTEST to send notify to parent of NM_NCHITTEST.
79 * 20. Cleaned up dead and/or testing code.
80 * 21. Support RB_MOVEBAND.
81 * 22. Support WM_STYLECHANGED and remove all (or most) of the GetWindowLong
82 * for GWL_STYLE.
83 * 23. Support RB_MINIMIZEBAND.
84 * 24. RBBS_HIDDEN (and the CCS_VERT+RBBS_NOVERT case) should be supported
85 * by all routines now.
86 * rev 7f
87 * 25. Fix handling of text color.
88 * 26. Correct implementation of WM_SETREDRAW to be closer to native.
89 * See REBAR_SetRedraw for doc changes of actual vs. MSDN
90 * 27. Do more implementation of RBS_AUTOSIZE in the WM_SIZE processor.
91 * 28. Implement RBBS_VARIABLEHEIGHT. Used by IE4.
92 * 29. Do more testing in WM_SIZE to handle strange cases like native.
93 *
94 *
95 * Still to do:
96 * 2. Following still not handled: RBBS_FIXEDBMP, RBBS_CHILDEDGE,
97 * RBBS_USECHEVRON
98 * 3. Following are only partially handled:
99 * RBS_AUTOSIZE, RBBS_VARIABLEHEIGHT
100 * 5. Native uses (on each draw!!) SM_CYBORDER (or SM_CXBORDER for CCS_VERT)
101 * to set the size of the separator width (the value SEP_WIDTH_SIZE
102 * in here). Should be fixed!!
103 * 6. The following messages are not implemented:
104 * RB_BEGINDRAG, RB_DRAGMOVE, RB_ENDDRAG, RB_GETCOLORSCHEME,
105 * RB_GETDROPTARGET, RB_MAXIMIZEBAND,
106 * RB_SETCOLORSCHEME, RB_SETPALETTE, RB_SETTOOLTIPS
107 * WM_CHARTOITEM, WM_LBUTTONDBLCLK, WM_MEASUREITEM,
108 * WM_PALETTECHANGED, WM_PRINTCLIENT, WM_QUERYNEWPALETTE,
109 * WM_RBUTTONDOWN, WM_RBUTTONUP,
110 * WM_SYSCOLORCHANGE, WM_VKEYTOITEM, WM_WININICHANGE
111 * 7. The following notifications are not implemented:
112 * NM_CUSTOMDRAW, NM_RELEASEDCAPTURE
113 * RB_CHEVRONPUSHED, RBN_MINMAX
