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:
