Package: mozilla-thunderbird
Version: 0.9-6
Severity: wishlist
Tags: patch
Hi,
The OverTheSpot mode of XIM is the most common input method for
Chinese/Japanese users,
but it is a pity that gtk2+ library don't support it.
There is a patch written by eliu (Vampire at Wicked Empire) <[EMAIL PROTECTED]>
could make gtk2+ library to support OverTheSpot mode.
Please visit http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=290469 for more
details.
But mozilla/mozilla-firefox/mozilla-thunderbird still need more patches to make
its supporting OverTheSpot mode.
The attached file is the patch for mozilla-firefox and mozilla-thunderbird.
After some testing, we feel that this patch is stable enough to update to the
upstream.
Please consider to apply this.
Thanks.
