2. float x = 100;
3. float y = 50;
4. float w = 50;
5. float h = 50;
6. int count=0;
7. void setup() {
8.   size(500, 500);
9.   background(255);
10.   stroke(0);
11.   noFill();
12.   fill(255);
13. }
14. 
    
15. void draw() {
16. 
    
17.   background(255);
18.   for (int i=0;i<60*7;i=i+60) {
19.     for (int j=0;j<60*5;j=j+60) {
20.       rect(x+j, y+i, w, h);
21.     }
22.   } 
23. 
    
24.   if (mousePressed) {
25.     for (int j=0;j<7*60;j=j+60) {
26.       for (int i=0;i<5*60;i=i+60) {
27.         if (mouseX>x+i && mouseX <x+w+i && mouseY>y+j&& mouseY <y+h+j) {
28.           println("Row="+mouseX+" Column"+mouseY);
29.           println("button number ("+((i/60)+1)+","+((j/60)+1)+") was pressed");
30.           fill(0); 
31.         }
32.       }
33.     }
