tigersoldier has another repository of ibus gjs and provides a nice lookup window of IBus, which is based on St actor (clutter).
I merged his lookup window into my repository yesterday. Thanks!
Yesterday I also integrated the new ibus-18.104.22.16810419-11 into Fedora 15 and rawhide.
# yum install --enablerepo=updates-testing ibus ibus-gnome3 # rpm -q ibus-gnome3 ibus-gnome3-22.214.171.12410419-11.fc15.x86_64
It also includes a patch from ueno-san, which can provide a separated package as ibus-gnome3.
The package ibus-gnome3 is a test package and I have to discuss with upstream whether the embedded function or the separated module is better.
Probably I have to fix vertical-horizontal window and have a few RFEs about enabling the clicking commit on the lookup window and adding a handle widget (likes Gtk.paint_handle).
