JScrollPane not repaint Canvas when scrolling?

Question

I trying to make a game where I add a Canvas to a JScrollPane but the canvas is larger than the visible area of the JScrollPane. So when I scroll the JScrollPane to see the rest I only see the blank area even though my Canvas is continuously redrawn. Anybody can help me??

Answer 1

It is common JScrollPane problem. To fix this with minimum fuss, call the following methods on your JScrollPane:

scrollpane.getViewport().setScrollMode(JViewport.SIMPLE_SCROLL_MODE);

Answer 2

Swing components do not work with heavyweight AWT components like Canvas. Use a JComponent or a JPanel instead of a Canvas
