NO! See Havoc's previous post...

Consider the following situation:

* Key pressed, without shift. Event generated and sent to X server.
* [... time passes whilst your GTK program does complicated processing]
* User finishes pressing key. [...time passes...]. User presses shift.
* [... time passes ... ]
* GTK+ program now reads key event, which was a key being pressed
  _without_ shift. You call get_pointer(...) and get shift being
  pressed. WRONG ANSWER!
