Swing send an event programmatically

How can I do to create a custom event and send it programmatically to a component?

E.g. If I had a JButton and wanted to create an ActionEvent or a MouseEvent and than send it as if an user had pressed on it which code I'd to use?

The following code not work:

JButton btn = new JButton("Click...");

MouseAdapter my = new MouseAdapter()
{
   public void mousePressed(MouseEvent e)
   {
      area.setText("Button clicked!!!");
   }
};
btn.addMouseListener(my);

MouseEvent me = new MouseEvent(btn, MouseEvent.BUTTON1, 1, 0, 1, 1, 1, false);
btn.dispatchEvent(my)开发者_运维技巧;

For your specific example you can simply call AbstractButton#doClick.

If you need to create synthetic events for the general case, make sure fill in all fields that a real AWTEvent would have, since the event handlers may take them for granted.

I think you can call the dispatchEvent method with the Event as an argument
