Relayout of JFrame?

[Knute Johnson]

I've got a JFrame app that has several components laid out with
GridBagLayout. One of the components is a JPanel that I draw an image
on. This component occaisionally can change size. After I resize my
JPanel, I invalidate it, repaint it and then call pack() on the JFrame.
Is there a way to cause the JFrame to relayout the components but not
shrink to fit the layout as it does with pack() but still grow if necessary?

Thanks,

I'm afraid nothing that does it automatically. But you can always query
the panel for its preferredSize and set the size of the frame
appropriately - making it bigger if required, but not shrinking it if
that is the case.

Try this:
public void layoutContainer(Container parent) {}

Try setting the minimumSize(Dimension d) to the minimum-size you want...

Thanks very much. That's kind of what I figured.
