Java AWT applet white screen when resizing window

Question

I have a java applet built using awt.

I draw some text on a panel object and everything goes fine. but when resizing the windows all the text disappears.

this behaviour is different among different jvms and platforms.

moving to swing isn't a possible option, because we have to maintain compatiblty with Microsoft JVM.

Answer 1

You must override update(Graphics g) and render your text in there. This method will be called when the window needs to be redrawn.

Answer 2

Without seeing your code, we have to guess, but is it possible that your text drawing is not being done in a paint() method? Read this for details on how AWT painting works.

Answer 3

Try attaching a ComponentListener which then calls paint() from within componentResized().

Something like:

class MyPanel extents Panel implements ComponentListner {
    public MyPanel() {
        addComponentListener(this);
    }
    public void componentResized(ComponentEvent e) {
        paint(getGraphics());
    }
}

Update: you should probably call 'repaint()' rather than directly invoking paint().
