This thread is for discussions of Programming with Swing.

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!!!

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!

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:

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.
