How do I force a container to repaint?

[Tom Niesytto]

Howdy (no I am not from TX),
let's assume I have a JFrame with FlowLayout.
I add some components to it and do setVisible().
Later I decide to change some layout parameter
eg. do setHgap() on the FlowLayout object.
Now - how do I force JFrame to repaint?
Thanks,
Tom

Just to enhance the question...
I tried to use update(Graphics) (after resetting hgap)
and adding my own paint(Graphics) method but then
the effect of changing hgap is visible only after
window is resized (and after going out of focus and back
to clear clutter).
Sorry for trivial question but I cannot seem to find the
answer in books that I have.

Try calling validate() (from Component) on the container.
