Question

I need to create some simple graphics using java. Basically what I need to do is draw a car using the Graphics class and make it move across a frame. I think that the way I should do this is:

Paint the graphics on a JPanel

Put the jpanel on the jframe

Then move the jpanel across the jframe

To give this illusion of movement I’m thinking that I should dynamically change the layoutmanager. Does this seem like a good or bad design?

Answer 1

When overriding paintComponent(Graphics), it is often best done in a JComponent rather than a JPanel.

As for moving the car, I would tend to draw it to a BufferedImage then draw the BufferedImage at different positions to simulate movement. The repaints can be controlled by a javax.swing.Timer.
