AWT flicker

843799Jul 15 2001 — edited Aug 6 2001
Hello everybody !
can somebody tell me ways to reduce awt flicker. It is becoming difficult to give real life touch to all those animations in applet.I have used both the versions of repaint().copyarea gives better results but it may not always be possible to use it.

I think you're in the wrong forum, baby.

But here is a solution:
	private Image bImage;
	private Graphics bGraphics;
	private int oldW;
	private int oldH;


	public void update(Graphics g){
		paint(g);
	}

	public void paint(Graphics g){
		if(getSize().width!=oldW || getSize().height!=oldH || bImage==null || bGraphics==null)
			resetBuffer(getSize().width,getSize().height,this);

		bGraphics.setColor(getBackground());
		bGraphics.fillRect(0,0,oldW,oldH);
		paintBuffer(bGraphics);
		g.drawImage(bImage,0,0,this);
	}

	public void resetBuffer(int w,int h,Component c){
		if(bGraphics!=null){
			bGraphics.dispose();
			bGraphics=null;
		}

		if(bImage!=null){
			bImage.flush();
			bImage=null;
		}

		System.gc();

		bImage=c.createImage(w,h);
		bGraphics=bImage.getGraphics();
		oldW=w;
		oldH=h;
	}

	public void paintBuffer(Graphics g){
		//	ADD YOUR NORMAL PAINT-CODE HERE

	}
Hope I helped ....
