Event when Panel visible

Question

Is there any event invoked, when a panel gets visible?
I have overwritten the paintComponent - Method, but it only works, if the window is repaintet, not when it's paintet first. So I want to call repaint, when the Pane gets visible.
Thanks for your help.

Hello,
I still have the same doubts but at least I have found a way to overcome it: if the Jinternalframe implements DropTargetListener and reject the drag on dragEnter and dragOver the dragevent won't be forwarded to the hidden JInternalFrame, something like:
private class MyInternalFrame extends JInternalFrame implements DropTargetListener
public MyInternalFrame()
super("TEST", true, true, true, true);
setDropTarget(new DropTarget(this, this));
public void dragEnter(DropTargetDragEvent dtde)
dtde.rejectDrag();
public void dragExit(DropTargetEvent dte)
public void dragOver(DropTargetDragEvent dtde)
dtde.rejectDrag();
public void drop(DropTargetDropEvent dtde)
public void dropActionChanged(DropTargetDragEvent dtde)
}
