You need to do two things (I think):
- Use a layout managerin your Frame; e.g. GridLayout(1,1)
- implement getPreferredSize() in your Canvas so that the layout manager knows how big it should be.
Note this is based on AWT. I don't know if Swing works exactly the same way.

Remove the call to super in the paint method and the string gets drawn. I didn't see the image though.
