hi,

Does somebody know how to change the positions of buttons in ControlP5 after the buttons are set up.
I have tried this bit of code but it doesn't work and i don't know why.
Thanks.

ControlP5 controlP5;
controlP5.Button tower, tryOwn, about, makeUp;

int colorActive =100;
int greyLight = 0;
int buttonPosX ;
int buttonPoxY;

void setup()
{
 size(500, 500);
 buttonPosX =5;   ///marginXleft+500+65;
buttonPoxY = height -60;

 controlP5 = new ControlP5(this);
 controlP5.Button tower  = controlP5.addButton("Load a Story",1,buttonPosX,buttonPoxY,80,20);
 tower.setColorBackground(greyLight);
 tower.setColorActive(colorActive);
 tower.setId(100);

 controlP5.Button tryOwn  = controlP5.addButton("Type Words",2,buttonPosX+90,buttonPoxY,80,20);
 tryOwn.setColorBackground(greyLight);
 tryOwn.setColorActive(colorActive);
 tryOwn.setId(200);  

 controlP5.Button about  = controlP5.addButton("Background",3,buttonPosX+(90*2),buttonPoxY,80,20);
 about.setColorBackground(greyLight);
 //about.setColorForeground (grey );
 about.setColorActive(colorActive);
 about.setId(300);  

 controlP5.Button makeUp  = controlP5.addButton("About the Visual",4,buttonPosX+(90*3),buttonPoxY,85,20);
 makeUp.setColorBackground(greyLight);
 makeUp.setColorActive(colorActive);
 makeUp.setId(400);  
 
 
}
void controlEvent(ControlEvent theEvent)
{
 //MAIN NAV BUTTONS
if( theEvent.controller().id() == 100)
 {
   println("controller : "+theEvent.controller().id());
   moveButtons();
 }
 else if( theEvent.controller().id() == 200)
 {
   println("controller : "+theEvent.controller().id());
  moveButtons();
 }
 else if( theEvent.controller().id() == 300)
 {
   println("controller : "+theEvent.controller().id());
  moveButtons();
 }
 else if( theEvent.controller().id() == 400)
 {
   println("controller : "+theEvent.controller().id());
   moveButtons();

 }
}

void moveButtons()
{
// buttonPosX =100;  
// buttonPoxY = height -60;
// tower.setPosition(buttonPosX, buttonPoxY);  
 
 tower.position().x = 10;
 tower.position().y = 10;
}
