controlP5 toggle multiple booleans

in Contributed Library Questions • 2 years ago

I'd like to toggle multiple booleans with one toggle in cp5.

I have two booleans showGrid and redrawGrid. When showGrid is toggled it should toggle the redrawGrid boolean which then gets toggled back after the grid is drawn to the buffer.

Do I use a listener? I can't figure out the syntax…

Thanks a ton,

Rob

I think this will work...

void showGrid(boolean theFlag) {
if(theFlag == true) {
showGrid = true;
if (showGrid == true) {
redrawGrid = true;
}
}
}
...
//draw grid
redrawGrid = false;

I don't always want to redraw it.. only when it's toggled…

The following works...

ControlP5 controlP5;
ShowGridToggleListener showGridListener;
Toggle tGrid;
void setup() {
controlP5 = new ControlP5(this);
controlP5.begin(10,10);
tGrid = controlP5.addToggle("showGrid",false,10,10,10,10);
showGridListener = new ShowGridToggleListener();
controlP5.controller("showGrid").addListener(showGridListener);
controlP5.end();
}
class ShowGridToggleListener implements ControlListener {
public void controlEvent(ControlEvent theEvent) {
showGrid = (theEvent.controller().value()==1)?true:false; // returns a float! not a boolean!
redrawGrid = !redrawGrid;
}
}

OK… now… ;)

How do I make the showGrid part of the ShowGridToggleListener class generic…

Essentially the following logic without knowing how to call that variable to toggle…

ie. I want this listener to listen to a bunch of toggles

class ToggleListener implements ControlListener {
public void controlEvent(ControlEvent theEvent) {
THE_VARIABLE_TO_TOGGLE = (theEvent.controller().value()==1)?true:false;
redrawGrid = !redrawGrid;
}
}
