Tue May 21 14:06:07 1996 Alexandre Julliard <julliard@lrc.epfl.ch> * [controls/button.c] Made ButtonWndProc a 32-bit window procedure. * [controls/desktop.c] Made DesktopWndProc a 32-bit window procedure. Added handling of WM_SETCURSOR. * [controls/menu.c] Allocate menu items and strings on the 32-bit system heap. Implemented Win32 versions for ChangeMenu, InsertMenu, ModifyMenu, AppendMenu and LoadMenuIndirect. * [controls/widgets.c] Added possibility to have 32-bit built-in classes. * [files/drive.c] Implemented GetLogicalDrive() and GetLogicalDriveStrings(). * [misc/spy.c] [include/spy.h] Added support for spying Win32 messages. * [loader/builtin.c] Fixed bug in -dll option parsing. * [memory/local.c] Added back the change by Huw D. M. Davies to free the block in LocalRealloc() before allocating the new one. * [objects/bitmap.c] [objects/cursoricon.c] [objects/oembitmap.c] Fixed bug in bitmap size that caused memory corruption for 24bpp. * [windows/defwnd.c] Implemented Win32 version of DefWindowProc(). * [windows/dialog.c] Implemented Win32 version of SendDlgItemMessage, Get/SetDlgItemText and Get/SetDlgItemInt. * [windows/mdi.c] Implemented Win32 version of DefFrameProc() and DefMDIChildProc(). Don't make a copy of the OBM bitmaps for every MDI window. * [windows/message.c] Implemented Win32 version of SendMessage(). * [windows/winproc.c] [windows/class.c] [windows/win.c] New scheme for 32-bit window procedures to replace aliases. All 32-bit window procedure get a 16-bit address pointing to a WINDOWPROC structure. Implemented Ansi<->Unicode translation for CallWindowProc(). Added translation of WM_DRAWITEM between Win16 and Win32. * [windows/win.c] [include/callback.h] Added ugly hack to build CREATESTRUCT on the stack when sending WM_NCCREATE. Implemented Win32 version of Get/SetWindowWord/Long and Get/SetWindowText. Fri May 17 10:20:16 1996 Albrecht Kleine <kleine@ak.sax.de> * [controls/button.c] Avoid gray text on gray background in disabled push buttons using a b/w raster and some raster operations (PatBlt,BitBlt). * [objects/text.c] DrawText(): don't draw an underbar anymore if DT_CALCRECT is set.
