Not-resizable (J)dialog showing Maximize Menu !!!

playwin2 · #1 (**permalink**) 09-07-2008, 01:16 AM

Hello,

Why not-resizable JOptionPane/JDialog's [setResizable(false)] shows "Maximize" in the System Menu?
(i.e. the menu you get when you right click on the title bar of the dialog.)

How should I stop this?

Here is a sample program to demonstrate the problem.
(Attached MDlg.java to zip)

Is this is a bug?

You're not showing a JDialog but rather a JFrame. If you want your window to act like a dialog, then make it a dialog:

Code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class MDlg
{
  private JPanel mainPanel = new JPanel();
  private JButton btnPop = new JButton("MsgBox");

  public MDlg()
  {
    mainPanel.setLayout(new FlowLayout());

    String txt = "<html>(1) First Right Click on my TitleBar.<br><br>"
        + "(2) Choose Maximize Menu.<br><br>"
        + "(3) Click on the Restore button on my TitleBar.<br><br>"
        + "(4) NOW - Click on the \"MsgBox\" Button.<br><br>"
        + "(5) Right Click on the TitleBar of the MessageBox.<br><br>"
        + "(6) Did you see the \"Maximize\" menu? Click on it!</html>";
    mainPanel.add(new JLabel(txt));
    mainPanel.add(btnPop);

    btnPop.addActionListener(new ActionListener()
    {
      public void actionPerformed(ActionEvent e)
      {
        JOptionPane.showMessageDialog(mainPanel, "Hello World!",
            "Right Click on HERE", JOptionPane.INFORMATION_MESSAGE);
      }
    });

    mainPanel.setPreferredSize(new Dimension(400, 300));
  }
  
  public JPanel getMainPanel()
  {
    return mainPanel;
  }

  public static void main(String args[])
  {
    EventQueue.invokeLater(new Runnable()
    {
      public void run()
      {
        //new MDlg().setVisible(true);
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        
        JDialog dialog = new JDialog(frame, "Test -- Right Click on HERE", true);
        dialog.getContentPane().add(new MDlg().getMainPanel());
        dialog.pack();
        dialog.setLocationRelativeTo(null);
        dialog.setVisible(true);
        
        frame.dispose();
      }
    });
  }
}

Ahh, sorry. I see that you were talking about the JOptionPane not the initial window. It sometimes does act a little funny.

Hello,

I don't get it, I'm talking about the JOptionPane's behavior in the above example, same thing happens in case of Dialog
For ex if I do : class myClass extends JDialog...etc.

btw: sorry for the main(frame) class name MDlg, are you reffering to it?

Edit: oops!

btw so you do thing it's a kind of a bug? no?

It's sure smelling like a Java bug, but I for one am very reluctant to call it as I just don't feel qualified to make that call or even accusation. I just searched the Java bug database and found what looks to be a related bug, but on closer examination it's not quite the same as it's for a much earlier version of Java and discusses a different problem:
Bug ID: 4219710 JOptionPane resizability

Perhaps the best thing to do is to submit a possible bug report to this database and see what falls out.

It seems that the attribute is carried from the parent. If you
MDlg.setResizable(false);
then neither have Maximize in their RC menus?

Looks like same one ... don't know why it marked closed.
