[Qemu-devel] [PULL 05/11] ui: convert key events to QKeyCodes immediately

[Gerd Hoffmann <kraxel@redhat.com>]

From: "Daniel P. Berrange" <berrange@redhat.com>

Always use QKeyCode in the InputKeyEvent struct, by converting key
numbers to QKeyCode at the time the event is created. This allows
the code processing / consuming key events to assume QKeyCode is
used. The only place we accept a key number in the InputKeyEvent
struct is with QMP commands sent by the user.
