I created a JInternalFrame and called setClosable(true).  The problem is that the frame does not close.  Any suggestions?

Hi mwalker,

How about using setClosed(true) or dispose().

Good luck

Are you saying that I have to add a window listener to the Internal Frame?  In the SwingSet applet example, I did not see in that in the code.  All that was done was a call to setClosable(true) on the frame.

Here is my code:

import java.awt.Container;
import java.awt.Component;
import java.awt.GridLayout;
import java.awt.BorderLayout;

import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import java.awt.event.FocusListener;
import java.awt.event.FocusEvent;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;

import com.sun.java.swing.JComponent;
import com.sun.java.swing.JInternalFrame;
import com.sun.java.swing.JPopupMenu;
import com.sun.java.swing.JPanel;
import com.sun.java.swing.JMenuItem;
import com.sun.java.swing.JSeparator;
import com.sun.java.swing.JButton;
import com.sun.java.swing.event.InternalFrameListener;
import com.sun.java.swing.event.InternalFrameEvent;

class CAARptViewer extends JInternalFrame implements InternalFrameListener
{
    private Container contentPane;
    protected JPanel thePanel;
    private JPopupMenu popupMenu;

    public CAARptViewer(String title)
    {
        super(title, false, true, true, true);

        contentPane = getContentPane();
        contentPane.setLayout(new GridLayout());

        // create and add the pane that holds the report
        thePanel = new JPanel();
        thePanel.setLayout(new GridLayout());
        contentPane.add(thePanel);

        setBounds(0, 0, 545, 175);
        try {
            setSelected(true);
        }
        catch (java.beans.PropertyVetoException e) {}

        addInternalFrameListener(this);
    }

    //{ Listeners
    public void internalFrameActivated(InternalFrameEvent e)
    {
        System.out.println("Window is activated");
    }
    public void internalFrameClosed(InternalFrameEvent e)
    {
        System.out.println("Closing internal window!");
        dispose();
    }
    public void internalFrameClosing(InternalFrameEvent e) { }
    public void internalFrameDeactivated(InternalFrameEvent e) { }
    public void internalFrameDeiconified(InternalFrameEvent e) { }
    public void internalFrameIconified(InternalFrameEvent e) { }
    public void internalFrameOpened(InternalFrameEvent e) { }
    //}
}

void setDefaultCloseOperation(int)
         int getDefaultCloseOperation()


Set or get the operation that occurs when the user pushes the close button on this internal frame. Possible choices
                                      are:

                                          DO_NOTHING_ON_CLOSE
                                          HIDE_ON_CLOSE (the default)
                                          DISPOSE_ON_CLOSE

                                      These constants are defined in the WindowConstants interface.

public void internalFrameClosed(InternalFrameEvent e)
          {
              System.out.println("Closing internal window!");
              dispose();
          }


replace with

public void internalFrameClosed(InternalFrameEvent e)
          {
              System.out.println("Closing internal window!");
              setVisible(false);
              dispose();
          }

Sorry, this didn't work for me either.  I should add that CAARptViewer is being added to an object subclassed from JDeskTop.  Any ideas would be greatly appreciated.

replace -->

public CAARptViewer(String title)
           {
               super(title, false, true, true, true);

               contentPane = getContentPane();
               contentPane.setLayout(new GridLayout());

               // create and add the pane that holds the report
               thePanel = new JPanel();
               thePanel.setLayout(new GridLayout());
               contentPane.add(thePanel);

               setBounds(0, 0, 545, 175);
               try {
                   setSelected(true);
               }
               catch (java.beans.PropertyVetoException e) {}

               addInternalFrameListener(this);
           }

with


public CAARptViewer(String title)
           {
               super(title, false, true, true, true);
               setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE );
               contentPane = getContentPane();
               contentPane.setLayout(new GridLayout());

               // create and add the pane that holds the report
               thePanel = new JPanel();
               thePanel.setLayout(new GridLayout());
               contentPane.add(thePanel);

               setBounds(0, 0, 545, 175);
               try {
                   setSelected(true);
               }
               catch (java.beans.PropertyVetoException e) {}

           }

I hate to be the bearer of bad news, but I added the call to setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE ) and it still did not work.

In your internal frame, add this:

addWindowListener(new WindowCloser());

and make an inner class:

class WindowCloser extends WindowAdapter
{
  public void windowClosing(WindowEvent e)
  {
    Window win = e.getWindow();
    win.setVisible(false);
    win.dispose();
  }
}
