Calling a method on a jFrame from a jPanel that created by the jFrame

Question

Hi all
I can not for the life of me work out how to do this.
Calling a method on a jFrame from a jPanel that created by the jFrame.
I have used this code to set a handle for one jPanel to another.
i.e I can create new jpanel and pass in handles from one to another but not back to the jFrame.
// this is sudo code
  private Panel_Top topPanel;
  private Menu_Panel menuPanel;
  private DataPanel dataPanel;
//create new
    topPanel = new Panel_Top();
    menuPanel = new Menu_Panel();
    dataPanel = new DataPanel();
// add handles from one to another
    menuPanel.setDataPanel(dataPanel);
    topPanel.setDataPanel(dataPanel);
    topPanel.setMenu_Panel(menuPanel);
    dataPanel.setMenu_Panel(menuPanel);
// in each class I use this to set
  public void setDataPanel(DataPanel dataPanel) {
    this.dataPanel = dataPanel;
  }But I can not seam to get a handle back to the jFrame that created it.
Please help
as you can see I am trying but no luck so far
Thanks
