Good afternoon.
I have problems with my slider and playback of events.

Copy code

import controlP5.*;
ControlP5 cp5;
RadioButton RadBut_courbe;
Slider Slider_analog;
int myColorBackground = color(0,0,0);
void setup() {
size(200,300);
cp5 = new ControlP5(this);
// RadBut_courbe= cp5.addRadioButton("radioButtonName",50,50);

// r.setSize(100,100);
// r.addItem("itemName",0);
radioButton();
control_analogique();
}

void draw() {
background(myColorBackground);

}

void radioButton() {

RadBut_courbe = cp5.addRadioButton("COURBA",178,38);// 30, 26
         // RadBut_courbe.setId(12);
       RadBut_courbe. setItemHeight(20);
       RadBut_courbe. setItemWidth(20);
       RadBut_courbe.setItemsPerRow (1);
       RadBut_courbe.setSpacingColumn(10);
       RadBut_courbe. setSpacingRow(15);
       RadBut_courbe.addItem("A0",0);
       RadBut_courbe.addItem("A1",1);
       RadBut_courbe.addItem("A2",2);
       RadBut_courbe.addItem("A3",3);
       RadBut_courbe.addItem("A4",4);
       RadBut_courbe.addItem("A5",5);
// RadBut_courbe.setImages(loadImage("imageDefault20_1.png"),loadImage("imageDefault20_1.png"), loadImage("imageActive20_1.png"));
}

void controlEvent(ControlEvent theEvent) {
// print(" "+theEvent.group());
print("got an event from "+theEvent.group().name()+"\t");
for(int i=0;i<theEvent.group().arrayValue().length;i++) {
print(int(theEvent.group().arrayValue()[i])); // valeur binaire
}
println("\t "+theEvent.group().value()); // id du radioboutton
myColorBackground = color(int(theEvent.group().value()*50),0,0);

}
void control_analogique(){

        // addSlider(theName, theMin, theMax, theDefaultValue, theX, theY, theW, theH)
        Slider_analog=cp5.addSlider("Analogique",1,1024,0,30,40+(35),110,15); // ajoute un Slider au ControlP5
        //Slider_analog.setWindow(controlWindow); // met l'objet dans la fenêtre
        //Slider_analog = (Slider)cp5.controller("MonSlider1"); // initialise l'objet Slider déclaré

        // méthodes propres à l'objet Slider
        //Slider_analog[i].setNumberOfTickMarks(10); // fixe le nombre crans - n+1 pour n valeurs
        //sliderCoeff.setNumberOfTickMarks((int(s1.max())+1); // fixe le nombre crans - n+1 pour n valeurs
        //Slider_analog[i].showTickMarks(true); // affichage des repères
        //Slider_analog.setSliderMode(Slider.FLEXIBLE); // fonctionnement du slider FLEXIBLE ou FIX

        // méthodes communes à tous les controles (objet Controller)
        Slider_analog.setLabelVisible(true); // affichage des labels
   /*     //Slider_analog[i].setLabel("Coefficient"); // fixe label objet
        Slider_analog.setDecimalPrecision(0); // fixe la précision
        Slider_analog.setColorActive(color(192,192,192)); // fixe la couleur active
        Slider_analog.setColorBackground(color(192,192,192)); // fixe couleur fond
        Slider_analog.setColorForeground(color(192,192,192)); // fixe couleur avant
        Slider_analog.setArrayValue(new float[] {00,1023} ); // fixe les valeurs min/max du Slider ?
        Slider_analog.setColorCaptionLabel(color(0)); // fixe couleur Label
        Slider_analog.setColorValueLabel(color(192,192,192)); // fixe la couleur valeur
      */
     } //fin de la boucle

when I click on it I get an error:

Copy code

Display 0 does not exist, using the default display instead.

possible errors that might occur in this method .
e.g. check for casting errors, possible nullpointers, array overflows ... .

But my reading is good for radiobutton.

Hi, inside controlEvent you will need to check if the event came from a controller or a group at the moment you are assuming all events are being triggered by a group inside your controlEvent function. using something like the following will help you to distinguish between a controller and a group:

Copy code

void controlEvent(ControlEvent theEvent) {
if(theEvent.isGroup()) {
// access the group with theEvent.getGroup()
} else if(theEvent.isController()) {
// access the controller with theEvent.getController()
}
}
