double buffering and createImage()

  • Follow


Hey,

   I have a canvas in a applet that I want to draw on. My problem is that I
don't know where to call createImage() to get my back buffer. I tried it in
the constructor, but I keep getting null returned to me.

Any suggestions?

Thanks,

//Rob

You have to make sure the component is 'realised' and displayable, I used
to do this in the paint() method, but found some better suggestions over
here:
