Wed Mar 13 19:46:50 1996 Alexandre Julliard <julliard@lrc.epfl.ch> * [controls/edit.c] Removed calls to memmove (not portable). * [debugger/dbg.y] [debugger/debug.l] Prefixed all token with 't' to avoid conflicts with type definitions. Added 'walk queue', 'walk class' and 'info class' commands. * [debugger/info.c] Moved queue and window information functions to windows/queue.c and windows/win.c respectively. * [loader/signal.c] Added SIGHUP handling to force entry into built-in debugger. Cleaned up a bit. * [misc/spy.c] General cleanup and performance improvements. * [windows/class.c] Added CLASS_DumpClass() and CLASS_WalkClasses() functions for debugger. * [windows/event.c] Pressing Ctrl-Alt-Return forces an entry into the debugger. Not sure if this key combination is a good choice... * [windows/message.c] [windows/queue.c] (New file) Moved message queue handling functions to windows/queue.c. Tue Mar 12 14:55:16 1996 Onno Hovers <onno@stack.urc.tue.nl> * [if1632/except.S] [include/except.h] [win32/except.c] (New files) Implemented Win32 exception functions: RaiseException(), RtlUnwind(), SetUnhandledExceptionFilter() and UnhandledExceptionFilter(). Mon Mar 11 19:23:29 1996 Albrecht Kleine <kleine@ak.sax.de> * [controls/listbox.c] [include/listbox.h] Special handling for COMBOLBOX styles introduced via extension of HEADLIST structure: lphl->dwStyle. Mon Mar 11 13:31:06 1996 Greg Kreider <kreider@natlab.research.philips.com> * [controls/combo.c] Any mouse movement within a small distance (defined by CBLMM_EDGE) of the top or bottom edge causes the window to scroll. Also moved some assignments so the routine works correctly. * [controls/listbox.c] Changing selection in ListBoxSetCurSel now updates PrevFocused. Added to LBSetFont and CreateListBoxStruct a fake hdc that tests and sets the standard text height. Sun Mar 10 08:39:23 1996 Alex Korobka <alex@phm30.pharm.sunysb.edu> * [windows/dce.c] Fixed memory leak in DCE_ClipWindows().
