Patch to add support for string conversion callbacks to
GtkIMContextXIM (#101814)
* modules/input/gtkimcontextxim.c: Set the string conversion callback
if supported by the XIC.
(struct _GtkIMContextXIM): Add string_conversion_callback member.
(struct _GtkXIMInfo, setup_im): Check and keep flag inidicating
whether string conversion callback is supported.
(gtk_im_context_get_ic, +set_string_conversion_callback,
+string_conversion_callback): Also initialize string conversion
callback, if supported, along with the IC initialization.
* modules/input/imxim.c: Make "xim" module default for Thai as well.
2004-04-23 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkclipboard.c (gtk_clipboard_wait_for_targets): Correctly
