To my delight indeed, I found that Alexandre Julliard
just commited several patchs for "support for dead key
used by XIM".
After compile the newest CVS, I found that I can not
input Chinese using this wine! But what's worse, when
I close the application ( I use notepad as a test),
debug window comes out, and if I close the debug
window, another one will comes up!
This patch is just for these two terrible problems.
After apply the changes made to
dlls/x11drv/x11drv_main.c ( described below, the
bottom item ), the second problem can be solve.
The first one need some more works as stated below.
(thanks for Dmitry Timoshkov's corrections)
BTW: one month ago, I submited a patch for all these
features and some more, but it had been ignored
without any comments. Hope this one would be
different.
ChangLog:
- controls/edit.c
new message type WM_IME_CHAR to handle XIM input.
- dlls/x11drv/keyboard.c
new function XIM_KeyEvent to process XIM key events.
- dlls/x11drv/window.c
new attributs added when creating a IC
- dlls/x11drv/x11drv_main.c
exchange the order of XCloseDisplay and XCloseIM
(otherwise it will crash when closed)
