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