GtkIMContext popup for on-screen-keyboard

[Cedric Sodhi <manday gmx net>]

Hello,

I've tried everything I could but could not find any solution to this: I
use a GtkIMContext to pop up a button to active the on-screen-keyboard
via dbus (without any intention to actually do any IM communication).
However, if that GtkIMContext gets activated, it subsequently renders
the entry unusable because (apparently I can't just create a
"transparent" GtkIMContext).

Any ideas how to solve that?
