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.

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.
This patch was needed for
https://bugzilla.redhat.com/show_bug.cgi?id=1297640
Setup was Windows client connecting to a Windows VM.
Without this patch, when remote-viewer is focused and the user is
interacting with the VM, it was not possible to press the
Zenkaku_Hankaku in order to switch input method within the VM.
Are you saying this is not needed, and that the situation I describe is working
even without calling ImmDisableIME?
I guess the patch does not fix 1297640.
I mean whether ImmDisableIME(-1) is called or not, Zenkaku_Hankaku is sent to spice-gtk with my test.
I think the root cause is that MapVirtualKey() cannot get the scancode of the released Zenkaku_Hankaku and the remote desktop cannot receive
Zenkaku_Hankaku.
I observed when the title bar of remote-viewer is focused, Zenkaku_Hankaku event is not sent without this patch.
But I guess the original submitter mistook the issue and the customer's issue would be that Zenkaku_Hankaku is not sent when the window of
remote-viewer is focused but not the title bar.
And I asked the customers if all the problems are fixed with the patched spice-gtk and without ImmDisableIME(-1).
Thanks,
Fujiwara
