JFRAME- JPANEL question

Question

I have a JFrame that holds a JPanel. If that JPanel needs to contact the JFrame how do I get access to parent? I tried panelname.getParent, when I did I got a
java.lang.ClassCastException
Any help would be great.

Answer 1

i think you have to buid your own JPanel class lyke this:
public class MyJPanel extends JPanel{
JFrame parent;
public MyJPanel(JFrame p){
parent = p;
// here you have access to the parent JFrame in your JPanel
public JFrame getParentFrame(){
return parent;
// here you return the parent of the JPanel
so in your JFrame class you add the JPanel like this:
getContentPane().add(new MyJpanel(this));
i hope it helps you. :)
