Release 970120 Sun Jan 19 11:46:48 1997 Alexandre Julliard <julliard@lrc.epfl.ch> * [loader/module.c] Fixed LoadModule() to always call the DLL initialization code. * [windows/event.c] Moved all the keyboard stuff to windows/keyboard.c * [tools/build.c] Fixed Win32 register functions. Sat Jan 18 22:24:41 1997 David Makepeace <D.Makepeace@mailbox.uq.oz.au> * [tools/makedep.c] Fixed bug which causes SEGV on Solaris x86. Fri Jan 17 18:32:27 1997 Frans van Dorsselaer <dorssel@rulhmpc49.LeidenUniv.nl> * [controls/edit.c] Implemented WM_UNDO, WM_CONTEXTMENU (temporary using WM_RBUTTONUP), WM_COMMAND, WM_INITPOPUPMENU, WM_SYSKEYDOWN. Fixed EM_SETSEL and some minor bugs (features). Hence: fully functional undo and a win95 menu with the right mouse button. * [include/resources.h] [resources/TODO] [resources/sysres_??.rc] Added a context menu for the edit control. Translations, please ... Fri Jan 17 08:29:52 1997 David Faure <david.faure@ifhamy.insa-lyon.fr> * [windows/event.c] Move EVENT_ToAscii to windows/keyboard.c (where name ToAscii) Fixed Keypad keys 0-9 and . in EVENT_event_to_vkey. Added 3-state handling of toggle keys (CapsLock, NumLock) in order to make them work with any X server. Toggle keys now generate WM_KEYDOWN and WM_KEYUP on each pressing. * [include/keyboard.h] Totally replaced the file (formerly containing the vkcase definitions) by the declaration of 'extern' variables contained by event.c and used by keyboard.c * [windows/keyboard.c] Started to rewrite VkKeyScan and MapVirtualKey, to make them use the table keyc2vkey or X functions only. ToAscii : added keypad 0-9 and . special case. Changed toggle keys active mask from 0x80 to 0x1. * [misc/keyboard.c] File deleted. Contents moved to windows/keyboard.c. * [misc/main.c] Added putenv XKB_DISABLE to disable XKB extension (which, when present, causes AltGr to change keyboard group instead of being a modifier). Tue Jan 14 22:56:43 1997 Philippe De Muyter <phdm@info.ucl.ac.be> * [windows/event.c] Do not assume NumLockMask is Mod2Mask, but compute it by scanning output of XGetModifierMapping for XK_Num_Lock. Tue Jan 14 15:49:49 1997 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [loader/pe_*.c] [include/peexe.h] [include/resource32.h] [debugger/*.c] General clean up. Changed defines/structures to match Windows NT SDK. * [loader/main.c] Don't crash on empty command-line. * [windows/winpos.c] winpos.c made win32 clean. * [misc/ntdll.c] Some string conversion additions. * [files/file.c] GetFileAttributes/GetTempFileName fixed. * [misc/ver.c] VerInstallFile implemented. Mon Jan 13 15:03:11 1997 Philippe De Muyter <phdm@info.ucl.ac.be> * [tools/build.c]: Use PREFIX also in stabs messages. Mon Jan 13 10:40:33 1997 John Harvey <john@division.co.uk> * [graphics/win16drv/*] [include/win16drv.h] Many fixes and some new features. * [graphics/x11drv/font.c] [graphics/x11drv/init.c] [include/x11drv.h] [objects/font.c] GetTextMetrics() moved to graphics driver. * [if1632/gdi.spec] [misc/fontengine.c] [misc/Makefile.in] New dummy EngineEnumerateFont, EngineRealizeFont functions. * [include/windows.h] TEXTFORM16 and FONTINFO16 structure definitions moved here from include/win16drv.h
