Strange Dialog!

I have created a LoginDialog class(derived from JDialog), LoginDialog have a frame as its member, this frame is the frame of the LoginDialog itself:
public class LoginDialog extends JDialog{
.......
private static JFrame dialogFrame = new JFrame();
static{
      dialogFrame.setSize(231, 199);
      dialogFrame.setVisible(true);
}

and in the constructor of LoginDialog :

public LoginDialog(boolean modal){
      super(dialogFrame, modal);
      setLayout(null);
      ......
      setSize(231, 199);
      pack();
}

and the main() :
public static void main(String args[]) {
     
        LoginDialog ld = new LoginDialog(true);
        ld.show();
    }


When I call the show() method, my dialog is too small, it has the title only! I have to resize it by mouse to see the components in it! It should have the size of 231px in width and 199px in height, I suppose!
AND : There's a another frame with the size of 231px in width and 199px in height!
I think this frame is dialogFrame, but I don't find any reason for it to appear on desktop!
I just want my dialog appear only!
Please help! Thanx

get rid of the pack call, as you are not using a layout manager

>  pack();

> There's a another frame with the size of 231px in width and 199px in height!

you create it, if you don't want it then don't create it, at least don't make it visible.

You also should be setting the layout of the dialogs content pane, and not the dialog directly:

getContentPane().setLayout(null);

if you don't need the frame then create your dialog without an owner.

>>LoginDialog have a frame as its member

public LoginDialog(boolean modal){
     super(dialogFrame, modal);  
     setLayout(null);
     ......
     setSize(231, 199);
     pack();
}


super(dialogFrame, modal);      <----this line, i afraid is to set the frame as the owner of the JDialog, and not as you have said, the frame IS a member of the dialog.

so if you don't want the frame to show up (you dont want a owner frame), you will have to go with objects comment.

The above example allows you to create your own GUI in MyPanel, then add it to the LoginDialog.
is this what you intended to do?
