How to stick a JDialog to a JFrame?

Question

it means when I click a button in my JFrame, a JDialog will be shown.I want to ban my JFrame, it won't be touch but still be shown on screen. I use command in my frame:

button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent evt) {
               MyDialog md=new MyDialog(MyFrame.this);
               MyDialog.setVisible(true);                 
            }
        });

And in class MyDialog extends JDialog:

public MyDialog(MyGUI myGUI) {
    super(myGUI,true);}

Have something wrong in my code? or Have another way to make it? Please help me!!

Do you mean to make the dialog [modal](https://en.wikipedia.org/wiki/Modal_window)? Have a look here: http://docs.oracle.com/javase/tutorial/uiswing/misc/modality.html — Cos64, Nov 06 '15 at 18:18
I don't see anything wrong your code. You're setting your dialog modal by doing `super(myGUI,true);` already, so what is your question / what isn't working? — Lukas Rotter, Nov 06 '15 at 18:20
yes, my program still work but not except. My JFrame still can be touched when My JDialog is opened. I don't know the difference between two commands above: new MyDialog(MyFrame.this) and new MyDialog(this). i wonder if itself is reason? — My Will, Nov 07 '15 at 06:14

Add this before MyDialog.setVisible(true);:

MyDialog.setModal(true);

EDIT: This has the same effect as the JDialog(Frame owner, boolean modal) constructor that you are already using. Are you sure you aren't already getting a modal dialog?

yes,JDialog and JFrame still work specially. I still can create the different JDialog when I click the button in JFrame. – My Will Nov 07 '15 at 06:19
