Swing stuff

[chris . roffler]

I am using the swing API for my application.  

I am trying to implement my own ToolTip manager for a Canvas.  I got
everything to work except
the location where the ToolTip is displayed on the screen.

I am using an InternalFrame with a JComponent for my canvas in it !
When the Internalframe does not have a menubar the location where the
tooltip is displayed is correct, with a menubar, the tooltip is
displayed at the wrong location ?


Here is the code :
(invoker is the canvas,  this code is taken from JToolTipManager)

public class JPopup
  extends JPanel
{
….

public void show(JComponent  invoker, int x, int y)
{
    Point p = new Point(x,y);

    SwingUtility.convertPoint(invoker, p, invoker.getRootPane());

    this.setBounds(p.x, p.y. this.getSize().width,
this.getSize().height());

    invoker.getRootPane().getLayeredPane().add(this,
JLayeredPane.POPUP_LAYER,0);
}
}

Does somebody have an idea what's going on ?


Thanks

Chris
