110413 - Mozilla XIM needs to call gdk_im_end() at UnsetFocus

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, enhancement)

Description

[Masaki Katakai]

This bug came from bug 109723.

Mozilla gtk widget now doesn't call gdk_im_end() when it's losing input focus.
It looks OK for IMEs but some IME want to know the sate of "losing focus" to
manage preedit and status. The codes would be very simple but we need to test
carefully.

 nsWindow::IMEUnsetFocusWindow()
 {
   KillICSpotTimer();
+  nsIMEGtkIC *xic = IMEGetInputContext(PR_FALSE);
+  if (xic) {
+    xic->UnsetFocusWindow();
+  }
 }

There is a problem that some IME's lookup (candidate window)
grabs the input focus and causes problem if gdk_im_end() is
called, e.g. ATOK12 on Solaris 8.

I would like to continue to use the currect codes.

gdk_im_end() is deprecated. If you see similar trouble on gtk2 build, please file a new bug.
