screenGeometry = QApplication.instance().desktop().screenGeometry()
to find out your desktop size in pixels.
availGeometry = QApplication.instance().desktop().availableGeometry()
is the same thing minus the space for the task bar, so maybe more
useful.

width, height = availGeometry.width(), availGeometry.height()

Finding out what pyside thinks the size is can be useful for debugging
problems, but this stuff should already be happening automatically.  There is
something not quite right with your layout, and brutally resizing things
by hand is treating the symptom, not the cause.
