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