Thu Jan 13 11:45:13 1994 John Richardson <jrichard@cs.uml.edu> * [window/win.c] Added functions EnableWindow, IsWindowEnabled, and helper WIN_SetSensitive. * [window/event.c] Added checks for WS_DISABLED windows in EVENT_key, EVENT_MotionNotify, EVENT_ButtonPress, EVENT_ButtonRelease, EVENT_ConfigureNotify, EVENT_FocusIn, EVENT_FocusOut, and EVENT_EnterNotify. Key and button presses beep for a disabled window. If anyone finds better places for these checks, please tell me. Jan 17, 94 martin2@trgcorp.solucorp.qc.ca (Martin Ayotte) * [misc/message.c] Cleanup on buttons answer value returned. * [control/combo.c] Now use OBM_COMBO bitmap dropdown button. Mon Jan 17 21:56:45 1994 Erik Bos (erik@trashcan.hacktic.nl) * [misc/comm/c] A few bugfixes. Tue Jan 18 06:36:48 1994 julliard@di.epfl.ch (Alexandre Julliard) * [loader/cursor.c] Added X cursor for IDC_SIZENS and IDC_SIZEWE. * [include/options.h] [misc/main.c] (New files) Rewrote main() function to get rid of Xt application context, and added command-line option parsing. * [objects/color.c] Use of a private map now configurable with command-line option. * [windows/defwnd.c] Added WM_SYSCOMMAND handling, and better WM_SETCURSOR handling. * [windows/event.c] Removed ConfigureNotify event handler (no longer needed). * [windows/message.c] Send WM_SETCURSOR message on mouse events. * [windows/nonclient.c] Use OEM bitmaps for the drawing of the non-client area. Added caption bar buttons handling, and moving and resizing of the window via the window frame (bypassing the window manager). * [windows/painting.c] Bug fix in BeginPaint(). * [windows/win.c] Set the override_redirect flag for windows (to bypass window manager). * [windows/winpos.c] Implemented WindowFromPoint(), ChildWindowFromPoint(), BringWindowToTop(), Get/SetInternalWindowPos(), Get/SetWindowPlacement(). Mon Jan 17 20:48:24 1994 Bob Amstadt (bob@pooh) * [memory/heap.c] Added support for multiple local heaps.
