Example 5-12: Multiple Mouse
Buttons
Processing also tracks which button is pressed if you have more
than one button on your mouse. The mouseButton variable can
be one of three values: LEFT, CENTER, or RIGHT. To test which button
was pressed, the == operator is needed, as shown here:
void setup() {
size(120, 120);
strokeWeight(30);
}
void draw() {
background(204);
stroke(102);
line(40, 0, 70, height);
if (mousePressed) {
if (mouseButton == LEFT) {
stroke(255);
