Canvas replace

[lorez]

I need to replace one Canvas by another. I suppose it should be:

public static void replaceCanvas(Canvas oldCanvas, Canvas newCanvas){
  oldCanvas = newCanvas;
}

Maybe I don't understand something?
The solution for me is:

public static void replaceCanvas(Canvas oldCanvas, Canvas newCanvas){	
  Layout parent = (Layout) oldCanvas.getParentElement();
  Canvas[] children = parent.getMembers();
    //another challenge - get position of member
  int pos = getPos(parent, oldCanvas);
  children[pos].destroy();
  children[pos] = newCanvas;
  parent.setMembers(children);
  parent.redraw();
}

But I sure there is better way to do it...
