   Hi.
   

   
   I have an ChildFrame inside of an DesktopFrame. I want to insert a JButton into the ChildFrame. But this JButton turns out to be very  tiny in that child frame. If I maximize the child frame, the button does not change size.
   I used this a source for my codings:
   

   
   http://www.rz.fhtw-berlin.de/hjp3/k100230.html
   

   
   I only added a JButton into my chid frame, I used a GridBagLayout. button.setSize() does  not seem to work in  that child frame.
   

   
   Would be very thankful, if anybody could help.

   jho....
   

   
   just call your child frames as follows
   

   
   public class MainFrame extends JFrame
   {
    ChildFrame1 child1;
   public MainFrame()
   {
    final JDesktopPane desktop = new JDesktopPane();
    getContentPane().add(desktop);
    
    JMenuBar bar = new JMenuBar();
   JMenu show = new JMenu("Show");
   JMenuItem showchild1 = new JMenuItem("Show Child1");
   //*******
   // here this represents the MainFrame which can be passes as a message to the child frame.
            child1 = new ChildFrame1(this);
   //*******
   desktop.add(child1);
   child1.setVisible(true);
    
   bar.add(show);
   show.add(showchild1);
   }
   }
   

   
   

   
   and in ChildFrame set the constructor as
   

   
   MainFrame  mainFrame;
   ChildFrame(MainFrame  mainFrame)
   {
   this.mainFrame = mainFrame;
   }
   

   
   actionPerformed in ChildFrame1()  {
    if(button clicked) {
       ChilFrame2 childFrame2 = new ChildFrame2();
        mainFrame.desktop.add(childFrame2);
        this.dispose(); // or this.hide();
    }
   }
   

   
   hope this code helps!

   i have a JFrame named MainFrame which also uses JDesktoPane. I created 2 JInternalFrame class named ChildFrame1 and ChildFrame2. When I can click the menu on the mainframe, it shows the childframe1. I must load the Childframe2 on the desktopPane on the mainFrame by clicking a button inside the childframe1. How can I do this??? My problem is that the desktopPane becomes foreign to childFrame2 since it is another class. here is the sample prog...
   

   
   public class MainFrame extends JFrame
   {
     ChildFrame1 child1 = new ChildFrame1();
   public MainFrame()
   {
     final JDesktopPane desktop = new JDesktopPane();
     getContentPane().add(desktop);
    
     JMenuBar bar = new JMenuBar();
    JMenu show = new JMenu("Show");
    JMenuItem showchild1 = new JMenuItem("Show Child1");
    desktop.add(child1);
    child1.setVisible(true);
    
   bar.add(show);
   show.add(showchild1);
   

   
   

   
   }
   

   
   }
   

   
   i still have another JInternalFrame class named childFrame2 but it will only be visible when i click a button in childFrame1 (child1).
   

   
   how can i do this?????
   

   
   i cannot use the jDESKTOPANE "desktop" because that class does not recognize the "desktop"
   

   
   

   
   PLEASE HELP ME!!! I WILL DEFINITELY APPRECIATE YOUR HELP! THANKS A LOT!!!
