I'm trying to extend the Surfomatic applet (see www.gamelan.com for full details) with a pretty frontend, including a canvas like so
public class Surfomatic extends Applet implements Timeable {
public void init() {
<snip>
MyCanvas h = new MyCanvas(this);
add("West",h);
show();
}
}
where MyCanvas is
class MyCanvas extends Canvas {
Image logo;
Surfomatic m;
MediaTracker eyeOut;
static final int BEGIN_ID = 0;
static final int FRAME_ID = 1;
URL nw;
public MyCanvas (Surfomatic l) {
m = l;
try {
nw = new URL("http://caligula.ssynth.co.uk/~rday/carpet.gif");
} catch (Exception e) {
System.out.println("Cant load image" + e.getMessage());
}
logo = m.getImage(nw);
eyeOut.addImage(logo, FRAME_ID);
try {
eyeOut.waitForID(FRAME_ID);
} //end try
catch(InterruptedException e) {} //e
resize(logo.getWidth(m),logo.getHeight(m));
}
public void paint(Graphics g) {
g.drawImage(logo,0, 0, m);
}
public boolean handleEvent(Event e) {
System.out.println("Handleevent");
return (super.handleEvent(e));
}
}
However, when it gets to getImage, it bombs out. Anyone any ideas? It works without implementing Timer, but I have no idea why.
Cheers,
Roger.
