Title:
  Full screen Qt windows don't get focus

Status in Unity:
  Invalid
Status in unity package in Ubuntu:
  Invalid

Bug description:
  The problem here is that when a Qt window/widget is shown by calling
  QWidget::showFullScreen(), the resulting full screen window doesn't
  get keyboard focus despite setFocus() being called. This is confusing
  especially with games using only keyboard since the user needs to
  click on the window.

  This is a bug in Unity, because the same code works correctly on
  Windows and Unity2D.

  Test program attached. It opens a full screen window, which exists and
  prints a message when it gets a key event.

  Steps to reproduce:

  1) Run the test program:
  $ qmake
  $ make
  $ ./FocusBug

  2) Press some keys.

  What should happen:
  - The program should exit and print a message "Key pressed!".

  What happens:
  - Nothing, unless the user first clicks on the window.
