/* * 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 * * TODO: * - vertical placement * - ComboBox and ComboBoxEx placement * - center image * - Layout code. * - Display code. * - Some messages. * - All notifications. * Changes Guy Albertelli * 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.) */ #include #include #include "winbase.h" #include "wingdi.h" #include "wine/unicode.h" #include "commctrl.h" #include "debugtools.h" DEFAULT_DEBUG_CHANNEL(rebar); typedef struct { UINT fStyle; UINT fMask; COLORREF clrFore; COLORREF clrBack; INT iImage; HWND hwndChild; UINT cxMinChild; UINT cyMinChild; UINT cx; HBITMAP hbmBack; UINT wID; UINT cyChild; UINT cyMaxChild; UINT cyIntegral; UINT cxIdeal; LPARAM lParam; UINT cxHeader; UINT lcx; /* minimum cx for band */ UINT hcx; /* maximum cx for band */ UINT lcy; /* minimum cy for band */ UINT hcy; /* maximum cy for band */ SIZE offChild; /* x,y offset if child is not FIXEDSIZE */ UINT uMinHeight; INT iRow; /* row this band assigned to */ UINT fStatus; /* status flags, reset only by _Validate */ UINT fDraw; /* drawing flags, reset only by _Layout */ RECT rcBand; /* calculated band rectangle */ RECT rcGripper; /* calculated gripper rectangle */ RECT rcCapImage; /* calculated caption image rectangle */ RECT rcCapText; /* calculated caption text rectangle */ RECT rcChild; /* calculated child rectangle */ LPWSTR lpText; HWND hwndPrevParent; } REBAR_BAND; /* fStatus flags */ #define HAS_GRIPPER 0x00000001 #define HAS_IMAGE 0x00000002 #define HAS_TEXT 0x00000004 /* fDraw flags */ #define DRAW_GRIPPER 0x00000001 #define DRAW_IMAGE 0x00000002 #define DRAW_TEXT 0x00000004 #define DRAW_RIGHTSEP 0x00000010 #define DRAW_BOTTOMSEP 0x00000020 #define DRAW_SEPBOTH (DRAW_RIGHTSEP | DRAW_BOTTOMSEP) #define NTF_INVALIDATE 0x01000000 #define NTF_CHILDSIZE 0x02000000 typedef struct { COLORREF clrBk; /* background color */ COLORREF clrText; /* text color */ HIMAGELIST himl; /* handle to imagelist */ UINT uNumBands; /* number of bands in the rebar */ UINT uNumRows; /* number of rows of bands */ HWND hwndToolTip; /* handle to the tool tip control */ HWND hwndNotify; /* notification window (parent) */ HFONT hFont; /* handle to the rebar's font */ SIZE imageSize; /* image size (image list) */ SIZE calcSize; /* calculated rebar size */ SIZE oldSize; /* previous calculated rebar size */ BOOL bUnicode; /* Unicode flag */ UINT fStatus; /* Status flags (see below) */ HCURSOR hcurArrow; /* handle to the arrow cursor */ HCURSOR hcurHorz; /* handle to the EW cursor */ HCURSOR hcurVert; /* handle to the NS cursor */ HCURSOR hcurDrag; /* handle to the drag cursor */ INT iVersion; /* version number */ POINTS dragStart; /* x,y of button down */ POINTS dragNow; /* x,y of this MouseMove */ INT ihitBand; /* band number of band whose gripper was grabbed */ INT ihitoffset; /* offset of hotspot from gripper.left */ REBAR_BAND *bands; /* pointer to the array of rebar bands */ } REBAR_INFO; /* fStatus flags */ #define BEGIN_DRAG_ISSUED 1 #define AUTO_RESIZE 2 #define RESIZE_ANYHOW 4 #define NTF_HGHTCHG 8 /* ---- REBAR layout constants.
