[Spice-devel] [PATCH] Disable IME to allow receiving all keys

[Takao Fujiwara]

My understanding is, Virt-Viewer with ImmDisableIME(-1) can send key events even if the title bar is focused when IME is enabled.
I attached the screenshot of the problem when ImmDisableIME(-1) is not applied.
https://bugzilla.redhat.com/show_bug.cgi?id=1311858#c42

But spice-gtk can receives all the key events and if ImmDisableIME(-1) is applied, users cannot switch IMEs during running Virt-Viewer.
I tested native client with Internet Explorer 10 in Windows 7 and I couldn't see any other differences when ImmDisableIME(-1) is applied.

If ImmDisableIME(-1) fixes only when the title bar is focused, I'd think the customer's bug is different and Virt-Viewer without ImmDisableIME(-1) 
might be more useful because it can switch IMEs during running Virt-Viewer.
I asked the customer if all the bugs can be fixed without ImmDisableIME(-1).

Thanks,
Fujiwara
