This will update every GUI object. Say you have a JFrame named Frame and it is your 'main' window:

Frame.update( Frame.getGraphics() );

That should repaint everything contained within 'Frame' as well as 'Frame' itself.

Oh... forgot to add that the 'update()' method is part of the java.awt.Container class and that the 'getGraphics()' method is part of the java.awt.Component class.

> Frame.update( Frame.getGraphics() );

you should not call update (or paint) directly.

I need to referesh the view of the GUI, cos since the GUI lets the user draw a circuit, at any point he might want to start all over again. so he presses refresh.
Well, i have to do it, even if it doesn't make sense or it will loose me marks in the exam! :-)

Thanks.

Sorry misunderstood what you meant by refresh.
It sounds like what you want to do is clear what the user has previously drawn. What you need to do for this depends on how you have implemented your drawing.
