Hello Experts!
I want to add some new buttons near the border icons (Close, Minimize,maximaise-Restore) and want to add glyphs or bitmaps as an icon on them. First, how can this be done so that I can define events for theses button when the user clicks on them. Secondly, is it possible to define hints for these buttons? If Yes, Please How?
Best regards,

If you are using java then you must use listeners.

After a button is created, you will add a listener to it. Eg,
b.addActionListener(listener_object);
When the button is clicked, a call is made to the actionPerformed method defined in the class of the listener object. An ActionEvent object is passed as a parameter to it.

Here is a simple example using awt that sets up a frame, adds buttons and labels , and also adds action listeners and window listeners.

import java.awt.*;
import java.awt.event.*;

public class FrameTest extends Frame implements ActionListener {

  private static final String HELLO = "Hello";
  private static final String GOODBYE = "Goodbye";
  private String message = HELLO;
  private Panel counterPanel;
  private Button counterButton;
  private Label counterLabel;

  public FrameTest() {
    super("HelloGoodbye");
    counterLabel = new Label(message);
    counterButton = new Button("Click me");
    counterButton.addActionListener(this);
    counterPanel = new Panel();
    BorderLayout b = new BorderLayout();//Predefined awt layout
    this.setLayout(b);
    counterPanel.add(counterLabel, BorderLayout.CENTER);
    counterPanel.add(counterButton, BorderLayout.SOUTH);
    this.add(counterPanel);
    addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e) {
        System.exit(0);;
      }
    });
    pack();
    setVisible(true);
    this.setSize(300,200);
  }

  public void actionPerformed(ActionEvent e) {
    if(message.equals(HELLO)) {
      message = GOODBYE;
    } else {
      message = HELLO;
    }
    counterLabel.setText(message);
    }

  public static void main(final String[] args) {
    FrameTest app = new FrameTest();

  }

}


Regards.

I also find it worrying that you have asked 3 questions and have not awarded points for any of them to the experts.

I agree with override y2k, dont we have some control regarding this matter; someone posting a question and experts spend time and efforts finding the solution, but some very inconsiderate one leaves their question seems that they dont care. Why? hard to give points? WEll, this is just an opinion. . "Just be considerate for someones effort" Besides this is an expert-exchange not a childs play.

Close this question and give points to override y2k -> All Parts of the Question were answered.
