How can handle JInternalFrame Close opeartion from JDesktopPane?

Question

I have one JFrame(HMSDoctor) and in that i am calling one JInternalFrame(CurrentOPD) by using JDesktopPane .

//opening JInternalFrame(CurrentOPD) by using JDesktopPane in JFrame(HMSDoctor).

       JDesktopPane jdp=new JDesktopPane();
   jdp.add(new CurrentOPD);

//Above code display proper JInternalFrame.

When i close that JInternalFrame at that time i want to execute one other JInternalFrame(Follow) in JFrame(HMSDoctor) .

How can i do like that?

Answer 1

See the section from the Swing tutorial on How to Write an Internal Frame Listener . I would guess you would want to listen for the "closed" event and then do some additional processing.

 public void actionPerformed(ActionEvent e) {
    if (SHOW.equals(e.getActionCommand())) {
        ...
        if (listenedToWindow == null) {
            listenedToWindow = new JInternalFrame("Event Generator",
                                                  true,  //resizable
                                                  true,  //closable
                                                  true,  //maximizable
                                                  true); //iconifiable
            //We want to reuse the internal frame, so we need to
            //make it hide (instead of being disposed of, which is
            //the default) when the user closes it.
            listenedToWindow.setDefaultCloseOperation(
                                    WindowConstants.HIDE_ON_CLOSE);

            listenedToWindow.addInternalFrameListener(this);
            ...
        }
    } 
    ...
}

是的，首先你必须在主frame添加addInternalFramaeListener ，当你的JInternalFrame(CurrentOPD)关闭时，你可以调用JInternalFrame(Follow)
