Hi i have a backbuffer and a graphicsbuffer :

 public Image offScreenImage;
 public Graphics offScreenGraphics;

in my paint() method i have this :

   width = getSize().width;
   height = getSize().height;


   // Create off screen image
   if(offScreenGraphics == null) {
      offScreenImage = createImage(width, height);
      offScreenGraphics=offScreenImage.getGraphics();
   }

how can i change the size of the image and the backbuffergraphics when my window is resized ?

Tx
Phil

Store the width and height.  Then as part of your if statement - say...

if(offScreen==null || storedWidth!=getWidth() || storedHeight!=getHeight) ....

Make sure you dispose() of the old graphics before recreating it...

The problem is that i want to do it only when i resized the window. Must I use a componentlistener ?

if yes do you have info about how to implement it ?
