[Spice-devel] [spice-gtk v1] widget: check if widget is realized before gdk_set_grab()

[Victor Toso]

From: Victor Toso <me at victortoso.com>

gdk_seat_grab() expects that the widget is visible otherwise it will
always fail with GDK_GRAB_NOT_VIEWABLE. This means that we can check if
display is realized before running gdk_seat_grab().

Fixes a critical & warning introduced by 3f4c5bcc88ca5db125e

 > Gdk-CRITICAL **: Window 0x17dcca0 has not been made visible in
 > GdkSeatGrabPrepareFunc
 > GSpice-WARNING **: keyboard grab failed 3
