Absent a complete example, it's hard to say with certainty. What is the
goal? What is the expected value of getWidth() when you double it. Are
you constructing GUI components on the event dispatch thread? What is
the layout of the enclosing Container? At what point do you pack() the
enclosing Window? For reference, you might compare what your doing with
this working example:
In general, you should not use setPreferredSize() in this way, and you
cannot rely on a component's size until it has been validated. You may
get some insight from the answers to this question:
