Dispatchevent (AWTEvent) Dispatch events

Click a button to display the dispatch of a specified event to the system.

Here is an example of assigning a new WindowEvent (this,windowevent.window_closing) event to the system when you click the Close button to close the entire window.

/* Show close window */import java.awt.*;import java.awt.event.*;import javax.swing.*;p ublic class via Dispatchevent (WindowEvent) Frametest extends JFrame implements actionlistener{  private JButton close;    Public Frametest ()  {    super ("close Window");        Container C=getcontentpane ();    C.setlayout (New FlowLayout ());        Close=new JButton ("Off");    Close.addactionlistener (this);        This.add (close);        This.setdefaultcloseoperation (jframe.exit_on_close);        SetSize (500,300);    SetVisible (True);  }    public void actionperformed (ActionEvent e)  {    Object obj=e.getsource ();    if (obj==close)    {      windowevent event=new windowevent (this,windowevent.window_closing);            The following two kinds of methods can be      this.dispatchevent (event);            Toolkit.getdefaulttoolkit (). Getsystemeventqueue (). postevent (event);    }    public static void Main (string[] args)  {    new Frametest ();}  }
