Jframe blues ( another validate, repaint question )

Question

i can use validate() or repaint() just fine when i use it via a JButton or a JOptionPane.
but when i use it via an event ( any event ) it doesnt work.
the background changes to the background color but no components are showing
when i click over where they're supposed to be they suddenly appear....
even better, i use an option in my jmenu that pops a JOptionPane, click on the ok button and
suddenly, all the components of me jframe suddenly appear!
well, can somebody tell me what to do after
frame.validate();
so that all the components shows?
thx

Answer 1

ok all is well .....
resolved the problem by starting a new thread
SwingUtilities.invokeLater(new Runnable()
public void run()
// insert the code that updates the UI here.
});
