1999-10-31 Tor Lillqvist <tml@iki.fi> * gdk/gdkkeysyms.h: Add new keysyms from X11R6.4 (including EuroSign). * gdk/gdktypes.h: Add note about wchar_t not necessarily being the same type as GdkWChar, especially on Win32. * gdk/win32/*.c: Change gdk_root_parent to be a pointer. * gdk/win32/*.c: Assume all strings are UTF-8. Convert to Unicode before passing to Windows GDI for drawing etc. Convert to the system default codepage before passing to Windows as window titles. * gdk/win32/gdkprivate.h: Add more fields to GdkWindowPrivate to support changing input locale on the fly. * gdk/win32/gdkevent.c: Support input language (keyboard locale) on-the-fly changes. Convert incoming characters from the current codepage to Unicode (and then to a UTF-8 multi-byte string) based on the current input language. Use keysym<->Unicode mapping tables and functions borrowed from xterm sources. Support IMEs (Input Method Editors) for CJK languages. On non-CJK editions of Win9x, use the ActiveX-based Active IMM (Input Method Manager) if available. IMEs and the Active IMM are available under the disguise of Chinese, Korean and Japanese support for IE and Outlook Express from "Windows Update" for Win98. On Win2k, the CJK support is present in all editions (as long as you install it). Call DispatchMessage from gdk_events_queue() (and thus gdk_WindowProc()), instead of duplicating the code in gdk_WindowProc(). Reworked the grab handling and propagation code, factored out duplicated code snippets into separate functions. Other cleanups, too. * gdk/win32/surrogate-dimm.h: Provide just the bits we need from the <dimm.h> header describing the Active IMM. * gdk/win32/gdkfont.c: Pretend to support fontsets, but so far just do the same as for "single" fonts. * gdk/win32/gdk.c: Call CoInitialize() (COM initialisation) from gdk_init_check, and CoUninitialize() from gdk_exit_func. Handle the new keysyms from gdkkeysyms.h. * gtk/gtkfontsel.c (Win32): Load the font for the preview as a fontset, so that gtkentry uses wide characters. * gtk/gtkrc.c (Win32): Get the locale with gwin_getlocale(). Call GTk+'s system directory "gtk+", not "gtk".
