Graphics MIDlet Example
This is the another graphic example, where we are going to draw a image that
look and act like satellite and earth. For creating these types of graphics in
J2ME we use MIDlet's. In the example we have created PacerCanvas class that extends the canvas class to draw this
graphics.
Please find the methods that are used in this example..
getWidth();
getHeight();
setColor(255, 162, 117);
fillRect(0, 0, w, h);
setColor(0, 0, 255);
drawLine(0, w - x, x, 0);
drawRect(z, z, 30, 30);
fillRoundRect(z, z, 30, 30, 10, 10);
drawArc(z, z, 30, 30, 0, 360);
The Application is as follows:
Source Code of PacerExample.java
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class PacerExample extends MIDlet{
public void startApp(){
Displayable d = new PacerCanvas();
d.addCommand(new Command("Exit", Command.EXIT, 0));
d.setCommandListener(new CommandListener() {
public void commandAction(Command c, Displayable s) {
notifyDestroyed();
}
});
Display.getDisplay(this).setCurrent(d);
}
public void pauseApp(){}
public void destroyApp(boolean unconditional){}
}
class PacerCanvas extends Canvas{
public void paint(Graphics g){
int w = getWidth();
int h = getHeight();
g.setColor(255, 162, 117);
g.fillRect(0, 0, w, h);
g.setColor(0, 0, 255);
for(int x = 0; x < w; x += 20){
g.drawLine(0, w - x, x, 0);
}
int z = 100;
g.drawRect(z, z, 30, 30);
z += 20;
g.fillRoundRect(z, z, 30, 30, 10, 10);
z += 20;
g.drawArc(z, z, 30, 30, 0, 360);
}
}
