Actually, there are two ways to make a full screen app... (not applet- don't confuse the issue with HTML and browser plugins- you have an unrestricted VM on the ePods, so use it!)
The easiest is to create an instance of java.awt.Frame, but do not call setVisible(true). Instead, create an instance of java.awt.Window, and give the Frame instance to the constructor as the owner. The "Window" object is a borderless entity- so set it to the size of the screen, and voila! Like this:
import java.awt.*;
public class bleah {
public static void main(String[] argv) {
Frame hidden = new Frame();
Window fullscrn = new Window(hidden);
fullscrn.setSize(new Dimension(640,480);
// now add Canvases or whatever to your new fullscreen window
fullscrn.setVisible(true);
}
}
The other way is to control the underlying OS window object directly via JNI- significantly more difficult, but also gives you the ability to programmatically cover the taskbar, etc. YMMV.
Hope that helps.
