No, you cannot put a JFrame in a JDesktopPane.  If you do a little
refactoring, you could move the UI components that you now have in JFrames
into JPanels.  You could them place the JPanels in either type of frame.
It should not be too hard to write a general utility to create the frame,
set up the menu, etc.

Of course!! However, as I stated before, you need to make JMenuBar a class
outside of your MainFrame and deploy your listeners and ActionEvents, in a
separate class as well. See the Tutorials and Examples on Swing development
on the JavaSoft site for details.


BTW, If you are going to be using JDesktopPane, then I would change my
JFrames to JInternalFrames.

I am using JinternalFrames in JFrame(JDesktopPane) now . I am getting difficulty in navigation in them...Let us say I have two Jinternalframes student & courses. I can set links to them from JFrame by using JMenubar. But when I try to set their link (as a requirement) inside Jinternal frame like From Student JinternalFrame when a button clicked it opens Course JinternalFrame in JdesktopPane but In Student JinternalFrame i did not have accesisbility of JDesktopPane instance to do work

have any suggestion please post it soon with details(and if possible with example)

Lodhi

I do not understand what you mean by "setting links to them using
JMenuBar" or "accesisbility of JDesktopPane instance".  If you have some
code that is not working as you expect, it would be a good idea to post
the actual code - ideally a complete, working example.  Descriptions of
the code are a poor substitute.

Thanks for your mail.

At very simple scenario...!

We have two JInternalFrames, One JIF is representing Student Contact Information, whereas the other JIF is representing Student Course Information.....

User Come and open the 'Student Contact Information Form' and enters student contact detail and then user clicks the "NEXT" button on JInternalForm of Student Contact Information. This button action displays Student Course Information Form......!
This is not working....! Navigating through buttons in JIFs.

However, if user clicks the Menubar item  'Student Contact Information' then it displays Student information form, and when user click MenuItem of 'Student Course Information' it displays the other form.

Actually one way is working and the other way is not.....!

public class Main extends JFrame implements ActionListener, InternalFrameListener
{
//here some code for jdesktoppane and menubar in jbinit
//including instance of jdpDesktop of JDesktopPane
//code for menuitems
  void jMenuItem1_actionPerformed(ActionEvent e) {
    JInternalFrame ct = new Student();
    try {
      jdpDesktop.add(ct, JLayeredPane.DEFAULT_LAYER);
      ct.addInternalFrameListener(this); // Listen for events
      jdpDesktop.moveToFront(ct);
      ct.pack();
      ct.show();
      ct.setSelected(true);
    } catch (PropertyVetoException ex) {
    }
  }

  void jMenuItem2_actionPerformed(ActionEvent e) {

    JInternalFrame bizt = new Course();
    try {
      jdpDesktop.add(bizt, JLayeredPane.DEFAULT_LAYER);
      bizt.addInternalFrameListener(this); // Listen for events
      jdpDesktop.moveToFront(bizt);
      bizt.pack();
      bizt.show();
      bizt.setSelected(true);
    } catch (PropertyVetoException ex) {
    }
  }

But If I want to go to Course InternalFrame from Student I add a JButton in Student class and want to show screen Course when user click on it 

public class Student extends JInternalFrame {
//some code here
 void jButton2_actionPerformed(ActionEvent e) {
    JInternalFrame c=new Course();
try {
//I did not have visiblity to this variable of Main class
//  jdpDesktop.add(c, JLayeredPane.DEFAULT_LAYER);

//or I create new instance of JDesktopPane and do it 
JDesktopPane jdp=new JDesktopPane();
      jdp.add(c, JLayeredPane.DEFAULT_LAYER);
//  c.addInternalFrameListener(this); // Listen for events
  jdp.moveToFront(c);

  c.setSize(400,400);
  c.show();
  c.setSelected(true);
c.setVisible(true);
} catch (PropertyVetoException ex) {
}

  }

My all tries are not working
What code I will write in above method.......

Thanks for your patience...respond soon

Lodhi

First, I should mention that when you include code in a post, it would
very helpful if you would format it reasonably.  Some newsreaders do not
handle tabs, so it is a good idea to untabify the code before you paste it
in.  If that does not work, you can just format it yourself in the message.

If you want to add a new JInternalFrame to the existing, instance of
JDesktopPane that is being displayed, then creating a new JDesktopPane
and adding it to that does not help.  You need to make sure you have
access to that existing instance.  One way to do this is to pass it an
argument in its constructor.

It would also make a lot more sense to write a single method to create the
new JInternalFrame.  Instead of placing that code in the ActionListener
for a menu item, extract that into a separate method which you call from
that ActionListener.  Then you can use the same method when you want to
create the frame from a different context.
