I am trying to convert a java application into an applet.
I had a JFrame which had a 5 JPanels on it so to convert it I made the JFrame into a JPanel (mainPanel) and made the class extend JApplet.

However, I cannot update any of the panels when the mainPanel is on the applet however with exactly the same code - when the mainPanel is on a JFrame it works and the panels update.

Can anyone help?
