Drawing multiple components flicker

Question

I am trying to draw a number of Checkboxes in a Frame. The problem is that it flickers really badly. Is there a good way to solve this problem.

Answer 1

make it double buffered,
but I don't think it's possible with the default objects
so u should use an extended canvase to draw the checkboxes in
class DoubleBufCheckBoxes extends Canvas
  public void paint( Graphics g )
    //create double buffer memory
    if( ( db == null ) || ( getWidth() != dbwidth ) || ( getHeight() != dbheight ) )
     dbwidth  = getWidth();
     dbheight = getHeight();
     dbImage  = Image.createImage(dbwidth, dbheight);
     db = dbImage.getGraphics();
     //draw your own checkboxes in db
     db.draw..etc etc
     //draw the buffer to the screen
     g.drawImage( dbImage, 0, 0, Graphics.TOP|Graphics.LEFT );
}
