Tutorial Addendum on Beat - Beat JInternalFrame

Internal Anatomy Listeners

    

The afterward program shows you how to make centralized anatomy listeners:

      myFrame.setContentPane(new JDesktopPane());

      JMenuItem myMenuItem = new JMenuItem("New");

    
      myMenuItem.addActionListener(this);

    
      myMenu.add(myMenuItem);

    
      myMenuBar.add(myMenu);

    
      myFrame.setJMenuBar(myMenuBar);

   }

   }

   }

   }

    
   accessible abandoned internalFrameClosing(InternalFrameEvent e) {

    
      System.out.println("Internal anatomy closing");

    
   }

    
   accessible abandoned internalFrameDeactivated(InternalFrameEvent e) {

    
      System.out.println("Internal anatomy deactivated");

    
   }

    
   accessible abandoned internalFrameDeiconified(InternalFrameEvent e) {

    
      System.out.println("Internal anatomy deiconified");

    
   }

    
   accessible abandoned internalFrameIconified(InternalFrameEvent e) {

    
      System.out.println("Internal anatomy iconified");

    
   }

    
   accessible abandoned internalFrameOpened(InternalFrameEvent e) {

    
      System.out.println("Internal anatomy opened");

    
   }

    
}

    

Run this program, you will see a bare anatomy with one card alleged "Frame". If you:

    

    
• Click "Frame" card and "New" card account to make first centralized frame.
  
      



    
• Click "Frame" card and "New" card account to make additional centralized frame.
  
      



    
• Click the abutting figure on the first centralized frame.
  
      



    
• Click the aerate figure on the additional centralized frame.
  
      



    
• Click the abbreviate figure on the additional centralized frame.
  
      



    
• Click the minimized angel of the additional centralized frame.
  
      



    

you will see the afterward letters generated from the centralized anatomy adviser methods.

    

 

    
Action performed              - Clicked "New" card item

    
Internal anatomy opened

    
Action performed              - Clicked "New" card item

    
Internal anatomy opened

    
Internal anatomy closing        - Clicked the abutting icon

    
Internal anatomy closed

    
Internal anatomy activated      - Clicked the aerate icon

    
Internal anatomy deactivated    - Clicked the abbreviate icon

    
Internal anatomy iconified

    
Internal anatomy activated      - Clicked the minimized image

    
Internal anatomy deiconified
