Using the Status Window - The Applet Class

In addition to displaying information in its window, an applet can also output a message to the status window of the browser or applet viewer on which it is running.

Using the Status Window

 

In addition to displaying information in its window, an applet can also output a message to the status window of the browser or applet viewer on which it is running. To do so, call showStatus( ) with the string that you want displayed. The status window is a good place to give the user feedback about what is occurring in the applet, suggest options, or possibly report some types of errors. The status window also makes an excellent debugging aid, because it gives you an easy way to output information about your applet.

 

The following applet demonstrates showStatus( ):

 

// Using the Status Window.

import java.awt.*;

 

import java.applet.*; /*

 

<applet code="StatusWindow" width=300 height=50> </applet>

 

*/

 

public class StatusWindow extends Applet { public void init() {

 

setBackground(Color.cyan);

 

}

 

// Display msg in applet window.

public void paint(Graphics g) {

 

g.drawString("This is in the applet window.", 10, 20);

showStatus("This is shown in the status window.");

 

}

 

}
