key combinations? like ALT+a?
Jun 2^nd, 2005, 3:10am

hey ho! I wondered how if I could code a piece in the way that some actions whould happen if I push ALT and 'a' at the same time etc. This would be really cool. I want to use processing as displayer for some animations and as a GUI for Supercollider (SC3) at the same time for a live performance. So I need a lot of "buttons". Any help is appreciated

Reply #1 - Jun 2^nd, 2005, 11:51pm you can use the keyCode variable: http://processing.org/reference/keyCode.html or for full control, use java's methods for getting info from a KeyEvent object, which is updated on each key event inside processing, and available as a variable called "keyEvent". i.e. int c = keyEvent.getKeyChar();

but how can I identify inside the keyevent the key im pressing, for making some ifs results?
The other part, how can i say to proccessing, if F1 or F2 or Cpas LOck or print screen is pressed, do anything, where can i find the code for doing those things? i ve seen something like the equivalency on Ascii numbers but where is some chart or anything to do it?
the keyevent works on the alpha version?

see the java documentation on using keyEvent:
http://java.sun.com/j2se/1.3/docs/api/java/awt/event/KeyEvent.html

then implement via something like this:

void keyPressed() {
// "key" has the keyEvent.getKeyChar();
// "keyCode" has keyEvent.getKeyCode();
// if you want any of the other info, you can use the
// "keyEvent" object that's built into processing
}
