Tue Apr 12 00:05:31 1994 Bob Amstadt (bob@pooh) * misc/spy.c (SpyInit): Added more message types * [windows/mdi.c] [include/mdi.h] Maximizing and restoring child windows. Tiling of child windows. Mon Apr 11 20:48:28 1994 Alexandre Julliard (julliard@lamisun.epfl.ch) * [windows/winpos.c] Revert focus and activation to previous window when hiding a window. * [windows/syscolor.c] Implemented system color objects (brushes and pens created at SetSysColor() time for better performance). * [windows/graphics.c] [windows/nonclient.c] [controls/button.c] Changed painting code to use system color objects. * [windows/message.c] New function MSG_InternalGetMessage() for internal messages loops (e.g. for dialogs or menus). * [windows/hook.c] [include/hook.h] (New files) Beginning of the window hooks implementation. * [windows/dialog.c] Use new function MSG_InternalGetMessage() in DialogBox(). * [if1632/callback.c] Added function CallHookProc(). Apr 11, 94 martin2@trgcorp.solucorp.qc.ca (Martin Ayotte) * [windows/event.c] Bug fix : WM_CHARs are sent to focused window like WM_KEY???. * [misc/exec.c] Nothing much more than a stub for LoadModule(), I saw there a lot to be done in that corner, I will come back later ... * [loader/library.c] New functions GetWindowTask(), GetNumTask(), EnumTaskWindows() and associated modules & tasks linked-lists. (it's only an 'emerging bud', more to come next weeks). * [loader/wine.c] Use LoadLibrary() instead of LoadImage() for 'sysres.dll'. * [control/menu.c] You can now click outside menu region without problem. Keyboard navig more smootly, even if a child has the focus. Bug fix in InsertItem(), (bad linklist when insert point not found). change Realloc for Free & Alloc in ModifyItem(). MF_STRING now set BLACK_PEN to fix bug of bad color of the underscores done by DrawText(), (maybe it should done in DrawText() itself ?).

Added non-blocking WSAAsyncGetXbyY() functions as blocking ones. * [loader/wine.c] Added IsDLLLoaded(), used in LoadImage() to prevent loading a dll multiple times. Directory is added to wine's path when a fullpath is supplied when starting wine. LoadImage(): DLL filename used instead DLL's own internal name, fixes 'Bad DLL name' errors.
