Method Detail

keyTyped

void keyTyped(KeyEvent event)

This method is called when a key is typed. A key is considered typed when it and all modifiers have been pressed and released, mapping to a single virtual key. If a key is held down, this event will repeat.

Parameters:

event - the KeyEvent indicating that a key was typed

keyPressed

void keyPressed(KeyEvent event)

This method is called when a key is pressed. A key is the unshifted/unmodified key such as '/' (there can be no '?' key press). In standard Java it will repeat if the key is held down, but in leJOS it is only called once when a key if pressed as this seemed to be more useful.

Parameters:

event - the KeyEvent indicating the key press

keyReleased

void keyReleased(KeyEvent event)

This method is called when a key is released.

Parameters:

event - the KeyEvent indicating the key release
