hiding other things with controlP5 hide function
Oct 7th, 2008, 9:05am  
i'm trying to hide a FPS indicator along with controlP5 controls, using controlP5's convenient built-in option/alt-h key command.  however i cannot get that key combo to be recognized.  i tried booleans to keep track of alt/option key on press and release and that didn't work.  also tried JS keyEvent.isAltDown() function as per this thread:
http://processing.org/discourse/yabb_beta/YaBB.cgi?board=Syntax;action=display;num=1208144196

but that didn't work either.  it seems i can't override controlP5's handling of that particular key combo.   if i swap their order, i can see both 'h' and 'alt' keys are recognized, but not together.  how should i do it?

Code:

void keyPressed() {
  if (key == 'h') {
    println("h"); 
    if (keyEvent.isAltDown()) {
	println("alt/option + h : hide controls AND fps indicator");
	fpsDisplay.hide();
    } 
  }
}

this might help. instead of using
Code:

key=='h'

use the keyCode of h
Code:

keyCode==72


(alt has to be pressed before h.)
example:

Code:

boolean isVisible;

void setup() {
  size(400,400);
}

void draw() {
  background(0);
  if(isVisible) {
    fill(255,0,0);
    rect(10,10,40,40);
  }
}

void keyPressed() {
  //println(keyCode);
  // 72 is the keyCode for h
  if(keyCode==72 && keyEvent.isAltDown()) {
    isVisible = !isVisible;
  }
}

that worked, thanks.  curious, why would supplying keyCode work and key=='h' not work when key=='h' is recognized without controlP5 running?
