Thread: Preventing a JFrame from Being Iconified

Hi!

I'm creating a program to manage the March Madness stuff my family does, so I can expand my knowledge of Java.

Right now, I'm encountering a problem with the "New Tournament" dialog box... In the main program's GUI, the user clicks a menu item "New tournament..." and then the "New Tournament" dialog box appears. However, I don't want to allow the user to click out of the "New Tournament" dialog box, or allow them to iconify it.

Right now, I'm using a WindowListener...

//See windowDeactivated and windowIconified
private class NewTournamentGUIWindowListener implements WindowListener
{
 
   public void windowClosing(WindowEvent e)
   {
 
      //This code is not part of the problem
      MainGUI.newTournamentWindowOpened = false;
      MainGUI.setStatus();
 
   }
 
   public void windowClosed(WindowEvent e)
   {
 
 
 
   }
 
   public void windowOpened(WindowEvent e)
   {
 
 
 
   }
 
   public void windowDeactivated(WindowEvent e)
   {
 
      /*
       * Whenever the user clicks outside the JFrame
       * it is deiconified and refocused.
      */
 
      setExtendedState(JFrame.NORMAL);
      requestFocus();
 
   }
 
   public void windowActivated(WindowEvent e)
   {
 
 
 
   }
 
   public void windowDeiconified(WindowEvent e)
   {
 
 
 
   }
 
   public void windowIconified(WindowEvent e)
   {
 
      /*
       * Whenever the user attempts to iconify the window
       * it immediately deiconifies itself; however, this process
       * looks sloppy. How can I deactivate the "Minimize" icon
       * that occurs at the top right of the JFrame?
      */
 
      setExtendedState(JFrame.NORMAL);
 
   }
}

Does anyone know how to prevent a window that I've created from being iconified?

You don't mention how you are creating your dialog, but what about using a modal JDialog?

Okay, I did some research on modal dialogs, and appended my code a little. Before, it was like this...

public class NewTournamentGUI extends JFrame
{
 
   //... ...
 
   public NewTournamentGUI
   {
 
      super("New Tournament");
 
      //... ...
 
   }
 
   //... ...
 
}

...and now it's like this...

public class NewTournamentGUI extends JDialog
{
 
   //... ...
 
   public NewTournamentGUI
   {
 
      super(new JFrame(), "New Tournament", Dialog.ModalityType.APPLICATION_MODAL);
 
      //... ...
 
   }
 
   //... ...
 
}

And now it works just the way I wanted to! Thank you very much!
