| Name | keyTyped() |
|---|---|
| Examples | // Run this program to learn how each of these functions
// relate to the others
void draw() { } // Empty draw() needed to keep the program running
void keyPressed() {
println("pressed " + int(key) + " " + keyCode);
}
void keyTyped() {
println("typed " + int(key) + " " + keyCode);
}
void keyReleased() {
println("released " + int(key) + " " + keyCode);
} |
| Description | The keyTyped() function is called once every time a key is pressed, but action keys such as Ctrl, Shift, and Alt are ignored. Because of how operating systems handle key repeats, holding down a key will cause multiple calls to keyTyped(), the rate is set by the operating system and how each computer is configured. |
| Syntax | void keyTyped() {
statements
} |
| Returns | None |
| Usage | Web & Application |
