Drop Down Menu using controlP5, controlEvent monitor doing nothing.

MarbleMad

Hi all. First post here so please be gentle :-)

Been trying to get a drop down menu to work, based on the example below, the menu displays and responds fine but i can't figure out how to read what 've actually selected. The "controlEvent" doesn't appear to respond as I click on menu items. Tried processing 2 and 3 and updated my controlP5 library.

Can anyone offer any help? Thanks.

import controlP5.*;
ControlP5 cp5; // you always need the main class
 int b = 0 ;
void setup() {
  size(300, 300);
  cp5 = new ControlP5(this);

  // add a dropdownlist at position (100,100)
  DropdownList droplist = cp5.addDropdownList("mySuperList").setPosition(100, 100);

  // add items to the dropdownlist
  for (int i=0; i<5; i++) {
    droplist.addItem("myItem " + i, i);
  }
}

void draw() {
  background(0);
  // controlp5 autodraw is on by default (if you use the default JAVA2D renderer)
  // this means the gui is automatically drawn at the end
}

// controlEvent monitors clicks on the gui
void controlEvent(ControlEvent theEvent) {
  if (theEvent.isGroup()) {
    println(theEvent.getGroup() + " => " + theEvent.getGroup().getValue());   // *** this isn't responding ***
  }
}

Ok, figured it out. Not entirely sure what the distinction is and why several examples had the code above but changing isGroup and getGroup to isController and getController appears to fix things up:

    // controlEvent monitors clicks on the gui
    void controlEvent(ControlEvent theEvent) {
      if (theEvent.isController()) {
        println(theEvent.getController() + " => " + theEvent.getController().getValue());   // *** this isn't responding ***
      }
}
