frame calling another frame

[Benjamin Mulder]

Background: : I have two frame/classes. A login screen and a "display results" screen. A login screen has a login button which takes you to display results screen.
Display eesults screen as a logout button however...

Problem: when you click on the logout button, it generates two instances of the login screen. In other words, two login screens appear one on top of the other on the left hand corner NOT in the center like the first time the program launches.

Behavior I want: once I click logout on "display results" screen, I go right away to the login screen. Exactly the way it previously was: centered and with only one instance running not two as it is right now.

This is on the login screen.

 void loginbtn_actionPerformed(ActionEvent e)
{
 
//if login successful, you will get the results screen
Display results = new Display();
results.setVisible(true);
results.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(false);
 
}

this is on the results screen

 
void loginOutbtn_actionPerformed(ActionEvent e)
{
//go back to login screen.
Welcome loginScreen = new Welcome();
loginScreen.setVisible(true);
loginScreen.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(false);
 
}

thanks in advance....

You only need one JFrame to do what you are doing.

You could use a CardLayout. Create two JPanels, a login one and a results one. Add them both to the CardLayout. When you press the login button, simply have the CardLayout show the other panel. Likewise, have the results page show the login panel.

You can simply update the content of the results panel before you show it.

Should work like a charm.
