JInternalFrame.JDesktopIcon class

[Bottlenecked]

Hello guys,

I am quit confused about some concepts of java classes. For me java programmings seems quit tough to understand. I am not able to understand the concept of 'JInternalFrame.JDesktopIcon class' of java. I have referred lots of advanced java book, but didn't get enough details over this class. I wonder if your are able to provide me some details about the JInternalFrame.JDesktopIcon class of java. I would really appreciate your any help.

A JInternalFrame.JDesktopIcon class component represents an iconified version of a JInternalFrame. This API should NOT BE USED by Swing applications, as it will go away in future versions of Swing as its functionality is moved into JInternalFrame. This class is public only so that UI objects can display a desktop icon. If an application wants to display a desktop icon, it should create a JInternalFrame instance and iconify it.

Hi friend,

See if something below code for JInternalFrame.JDesktopIcon class can help you or not:

javax.swing.JInternalFrame.JDesktopIcon

public class FTdemo extends JFrame {
  private JDesktopPane desk01;

  public FTdemo(String title) {
    super(title);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    desk01 = new JDesktopPane();
    setContentPane(desk01);
  }

  private void addFrame(int number) {
    JInternalFrame f03 = new JInternalFrame("Frame " + number, true, true,true, true);
    f03.setBounds(number * 10 - 5, number * 10 - 5, 250, 150);
    desk01.add(f03, 1);
    f03.setVisible(true);
  }

  public static void main(String[] args) {
    Figure3 tdW = new Figure3("");

    tdW.setSize(400, 220);
    tdW.setVisible(true);
    f03or (int i = 1; i <= 4; i++) {
      tdW.addFrame(i);
    }
  }
}
