Re: [virt-tools-list] [PATCH virt-viewer] Forward directly key events to display

Even if the display is disabled, we should keep sending key events to
guest. It can wake up from sleep for instance.

There is a single widget per window, so we can directly send key
events there. If the menu is active, it has the grab, so the window
doesn't receive those key events.
