| Examples |
# Drag (click and hold) your mouse across the image to change the
# value of the rectangle
value <- 0
draw <- function() {
fill(value)
rect(25, 25, 50, 50)
}
mouseDragged <- function() {
value = value + 5
if (value > 255) {
value = 0
}
}

| Description |
The mouseDragged() function is called once every time the mouse moves while a mouse button is pressed. (If a button is not being pressed, mouseMoved() is called instead.) Mouse and keyboard events only work when a program has draw(). Without draw(), the code is only run once and then stops listening for events. |
| Syntax | mouseDragged() mouseDragged(event) |
