1999-11-07 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkprivate.h: New font private structures, related to fontsets. * gdk/win32/gdkfont.c: New functions gdk_font_list_new() and gdk_font_list_free(). On X11, will just be wrappers to XListFonts() and XFreeFontNames(). On Win32, the code previously in gtkfontsel.c is now here. New function gdk_font_xlfd_create(). On X11 will get the FONT property of the font (for GDK_FONT_FONTs), or call XBaseFontNameListOfFontSet (for GDK_FONT_FONTSETs), on Win32 builds a XLFD style name from the font information in the LOGFONT struct(s). New function gdk_font_xlfd_free(), which correspondingly frees the string returned by gdk_font_xlfd_create(). Implement fontsets on Win32. Add a function that iterates over a wide char string and calls a callback function for each substring of wide chars from the same Unicode subrange (and thus probably available in the same real font). Improve the XLFD emulation a bit. * gdk/win32/gdkim.c (gdk_nmbstowchar_ts): Small bugfix. * gdk/win32/gdkevents.c: Workaround for suspected bug on Win2k Beta3, WM_IME_CHAR messages don't seem to contain the composed multi-byte char as with the Active IMM on Win9x. Oh well, handle WM_IME_COMPOSITION with GCS_RESULTSTR instead, use ImmGetCompositionStringW() to get the composed Unicode chars. * gdk/win32/gdkgc.c * gdk/win32/gdkdraw.c: Changes needed because of the font private struct changes. * gdk/win32/gdk.def: Add the new functions.
