Well, that might've been in the 1.5.1 versions, but I'm using the 2.0b7 version, and when I set the frame.setResizeable() to true, i could resize the window until the sketch area was no taller than a pixel, as shown here:




It does constrain the width though. If the sketch height is 0 pixels, it will throw and IllegalArgumentException, as the program is trying to draw something it can't. I'm no expert, but that's how I think it works.

Back to the question. You mention having to add a listener. We both know that this is not in the Processing reference. This is rather pure Java code.

Could you explain what a "listener" is, and how I could limit the sketch size with it?

Call this method from setup and it will create and add a window adapter to you sketch.

Explain.

How would I call this method from setup in the code listed below?

1. int ms = 0;
   
2. 
   
3. void setup() {
   
4.   frame.setResizable(true);
   
5.   size(600, 400);
   
6. }
   
7. 
   
8. void draw() {
   
9. 
   
10.   gui();
    
11. }
    
12. 
    
13. void gui() {
    
14.   switch(ms) {
    
15.     case 0:
    
16.       dMain();
    
17.       break;
    
18.   }
    
19. }
    
20. 
    
21. void dMain() {
    
22.   background(200);
    
23.   rectMode(CENTER);
    
24.   rect(width/2, height/2, width/3, height/15);
    
25.   rect(width/2, height/2 + height/5, width/5, height/15);
    
26. }

Don't mind the incompleteness. I plan to add the rest of the code later.

Thanks,
