managing parent frame from child frame on java swing
21,161
Solution 1
Pass in a reference to the parent frame when you create (or display) the child frame. This will require an overloaded constructor or display method.
Once the child has the reference, it can of course call any method that the parent exposes as public, like UpdateDate()
Solution 2
As of Java 1.3
public class MyPanel extends JPanel
{
public MyPanel() {
....
JButton cancelButton = new JButton("Cancel");
cancelButton.addActionListener(
new ActionListener() {
public void actionPerformed(ActionEvent e) {
// <<<< HERE'S THE INTERESTING BIT >>>>
javax.swing.SwingUtilities.getWindowAncestor(MyPanel.this).dispose();
}
}
);
add(cancelButton);
.....
}
}

I have a jframe (parent) which creates an input frame (child) where I get some parameter.
In the "child" frame I have "ok" and "cancel" buttons.
When "ok" button is pressed, the parent frame needs to be updated with new data.
What is the best way to do that??
