Deciding what to do if user closes window(JDialog)

Question

I am drawing shapes- Rectangle, Ellipse, Trianlge...I have big class that implements JFrame and it is used to draw the draw the shapes on the its content pane. Inside this class, I have an inner class that draws a custom JDialog frame. A user selects a shape from a MenuItem and the cuztom dialog frame pops up. This inner cuztom frame basically has textfields for user to enter specifications and it has a button for user to press if he/she finishes enterring the data. So user enters data in the inner frame and clicks on enter, then the Bigger(Outer) class draws the shape.
The problem is Even if the user clicks on close to close to the custom dialog, the shape is drawn. This is what I want to control. The Shape should only be drawn if the user clicks on enter.
Couls some guys offer help???
This is the code in the Outer Class. It calls the inner class so that the custom frame is popped up
if(e.getActionCommand().equalsIgnoreCase("Rectangle")) {
              showDialog() ;
              list.myList.add(new Rectangle( x, y, w, h, x3, y3, Fill, Outline)) ;
              model.addElement((list.myList.size()-1) + ": Rectangle ");
              repaint() ;
This is the inner class, but inside a method, so that I can call it in the outer class
public void showDialog() {
         class GetName extends JDialog 
           JPanel textF = new JPanel(new GridLayout(0,1)) ;
           JPanel labelF = new JPanel(new GridLayout(0,1)) ;
           JLabel XL1 = new JLabel("Add Xpos/X1") ; // the rest deleted because of space
           // the rest deleted because of space
           JFormattedTextField XT1 = new JFormattedTextField(new Integer("100"));
           public GetName() 
             setModal(true); 
             Container cont = getContentPane() ;
            //I have labels here but deleted them
             //because of the size limit to send here
          lebalF.addXL1) ; // the rest deleted because of space
             textF.add(XT1) ;
             cont.add(labelF, BorderLayout.CENTER) ;
             cont.add(textF, BorderLayout.LINE_END) ;
             JButton mybutt = new JButton("DrawShape"); 
             mybutt.addActionListener(new ActionListener(){ 
             public void actionPerformed(ActionEvent e){
                 x = Integer.parseInt(XT1.getText()) ;
                 y = Integer.parseInt(XT2.getText() ) ;
                 w = Integer.parseInt(XT3.getText() ) ;
                 ih = Integer.parseInt(YT1.getText() ) ;
                 x3 = Integer.parseInt(YT2.getText() ) ;
                 y3 = Integer.parseInt(YT3.getText() ) ;
                 // some deleted because of space
                 if(FilText.getText().equals("white"))       {Fill = Color.white;  }
                 else if(FilText.getText().equals("black"))  {Fill = Color.black;  }
                 else if(FilText.getText().equals("magenta")){Fill = Color.magenta;}
          // some deleted because of space
                 if(OutText.getText().equals("white"))       {Outline = Color.white;  }
                 else if(OutText.getText().equals("black"))  {Outline = Color.black;  }
                 else if(OutText.getText().equals("cyan"))   {Outline = Color.cyan;   }
                 dispose();}}); 
             cont.add(mybutt, BorderLayout.SOUTH) ;
             pack(); 
             setVisible(true); 
         } //End of internal class GetName
         new GetName();
     } //End of Public Method showTriDialog

Answer 1

My problem is solved.
I used a boolean variable and test : if(e.getSource() instanceof JButton && (JButton)e.getSource() == mybutt), then my boolean is set to true. So before I draw, i test of the boolean variable to see if it is true(meaning the button was clicked), if the boolean returns false, i skip the code that draws.
Thanks for response anyway.
//This code is in the inner class
if(e.getSource() instanceof JButton && (JButton)e.getSource() == mybutt) {
                  eventCheck = true ; //Check if user clicked on the button or closed the window
//This one in the outer class
public void actionPerformed(ActionEvent e)  {
           if(e.getActionCommand().equalsIgnoreCase("Ellipse")) {
              showDialog() ;
              if(eventCheck == true) {
              list.myList.add(new Ellipse( x, y, w, h, x3, y3, Fill, Outline)) ;
              model.addElement((list.myList.size()-1) + ": Ellipse ");
              repaint() ;
              eventCheck = false ;
            else return ;
          }
