For a long time, I've been able to create full-screen applications with the typical frame.setUndecorated(true) call and then relocating the frame to the top left corner of the screen with frame.setLocation(0, 0). However, I've always had to relocate the frame in the first frame of draw, otherwise it would fail to work.

I recently discovered that other people do not have this problem in the thread "Present" (full-screen mode) stretched across Multiple Screens, but it was rather distracting from the original problem, so I have come to write this post.

I'm running Windows 7 64 bit with both Processing 1.5.1 and 2.0a7.

From the thread above, the following code is supposed to work, although it doesn't:

1. public void init() {
2.   frame.removeNotify();
3.   frame.setUndecorated(true);
4.   frame.addNotify();
5.   super.init();
6. }
7. 
   
8. void setup() {
9.   size(displayWidth, displayHeight);
10.   frame.setLocation(0, 0); //This does not work
    
11. }
12. 
    
13. void draw() {
14.   println(millis());
15. }

I always end up using something like this:

1. void setup() {
2.   size(displayWidth, displayHeight);
3.   frame.setLocation(0, 0); //This doesn't work
4. }
5. 
   
6. public void init() {
7.   frame.removeNotify();
8.   frame.setUndecorated(true);
9.   frame.addNotify();
10.   super.init();
11. }
12. 
    
13. void draw() {
14.   if(frameCount == 1) frame.setLocation(0, 0); //This does
15.  
16.   println(millis());
17. }
