Forcing a repaint of a JLabel...

Thread view:

I'm writing something akin to the junit gui that shows each step of
the test passing as it goes. However, the JLabel that shows the
results refuses to repaint itself until the test has completely
finished. I tried calling invalidate() and repaint() on the JLabel
but nothing's working.

How can I force and immediate repaint of a component in swing?

paintImmediately(int x, int y, int w, int h);
paintImmediately(Rectangle r);

Does:

label.validate()
label.repaint()

work?

Stop blocking the event dispatch thread. A Google search for
SwingWorker should yield the information you need.

Thanks for the pointer. I've downloaded the class and will start
playing with it today.
