public class XYPanel

extends AbstractPanel

This class implement a panel that manages components derivated from fds.micro.ui.Component, and places them with absolute coordinates.

Here is a simple MIDlet that displays a tiled image:

 import java.io.IOException;
 import javax.microedition.lcdui.*;
 import javax.microedition.midlet.*;
 import fds.micro.ui.*;
 import fds.micro.ui.events.*;
 
 public class MyMidlet extends MIDlet {
 
     private XYPanel panel;
 
     public MyMidlet() {
         final int numberOfRows = 3;
         final int numberOfColumns = 3;
 
         // Panel
         this.panel = new XYPanel();
 
         // Image to use
         Image myImage;
         try {
             myImage = Image.createImage("/test.png");
         }
         catch(IOException ioe) {
             throw new RuntimeException();
         }
         int imgWidth = myImage.getWidth();
         int imgHeight = myImage.getHeight();
 
         // Add tiled images
         for(int row = 0; row < numberOfRows; row++) {
             for(int col = 0; col < numberOfColumns; col++) {
                 this.panel.append(new ImageItem(myImage), 10 + (col * imgWidth), 10 + (row * imgHeight));
             }
         }
 
         // Add a quit hyperlink
         final Hyperlink link = new Hyperlink("Quit hyperlink");
         link.addActionListener(
             new ActionListener() {
                 public void actionPerformed(ActionEvent evt) {
                     MyMidlet.this.notifyDestroyed();
                 }
             }
         );
         this.panel.append(link, 10, 20 + (numberOfRows * imgHeight));
     }
 
     protected void startApp() throws MIDletStateChangeException {
         Display.getDisplay(this).setCurrent(this.panel);
     }
 
     protected void pauseApp() {
     }
 
     protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
     }
 }
