controlP5 group event (Read 635 times)

moony YaBB Newbies Offline Posts: 7	controlP5 group event Dec 8^th, 2008, 6:47am hi, i started using the controlp5 library and it helps me a lot - great work. i tried to get an event from a control group by opening/closing it, but it does not work. do theese elements generate any event, when the state is changed? thanks, stefan

this is implemented now (0.3.6). when opening/closing a group, an event is sent to the controlEvent method. in order to receive events with controlEvent, the event has to be activated in the group, see example:

Quote:

import controlP5.*;

ControlP5 controlP5;

void setup() {
size(400,400);
frameRate(30);

controlP5 = new ControlP5(this);
ControlGroup l = controlP5.addGroup("myGroup",100,200);
// in order to receive events with controlEvent,
// the event has to be activated in the group.
// use:
l.activateEvent(true);

controlP5.addBang("A-1",0,4,20,20).setGroup(l);
controlP5.addBang("A-2",30,4,20,20).setGroup(l);

}

void draw() {
background(0);
}

void controlEvent(ControlEvent theEvent) {
if(theEvent.isGroup()) {
println("got an event from group "+theEvent.group().name()+", isOpen? "+theEvent.group().isOpen());
} else if (theEvent.isController()){
println("got something from a controller "+theEvent.controller().name());
}
}

thanks a lot. great work.

just another question concerning controlP5. i use many different controls for similar things and store the controller handlers in two arrays:

// P5groupAdc
ControlGroup P5groupAdc = controlP5.addGroup("Analog Input",20,200, 300);
for (int i = 0; i < 8; i++) {
P5groupAdcID[i][0] = controlP5.addToggle("channelOnOff" + i, true, 5, 15*i + 5 + 15, 10, 10);
P5groupAdcID[i][0].setGroup(P5groupAdc);
P5groupAdcID[i][0].setLabel("");

P5groupAdcID[i][1] = controlP5.addSlider("channelThreshold" + i, 0, 4095, 1000, 20, 15*i + 5 + 15, 155, 10);
P5groupAdcID[i][1].setGroup(P5groupAdc);
P5groupAdcID[i][1].setLabelVisible(false);

P5groupAdcID[i][2] = controlP5.addTextlabel("channelText" + i,""+i, 8, 15*i + 7 + 15);
P5groupAdcID[i][2].setGroup(P5groupAdc);

P5groupAdcID[i][3] = controlP5.addSlider("channelColor" + i, 0, 100, 12*i + 6, 180, 15*i + 5 + 15, 80, 10);
P5groupAdcID[i][3].setGroup(P5groupAdc); // set group
P5groupAdcID[i][3].setLabelVisible(false); // label off

P5groupAdcIDtxt[i] = controlP5.addTextlabel("channelThresLabel" + i," ", 25, 15*i + 7 + 15);
P5groupAdcIDtxt[i].setGroup(P5groupAdc);
}

in order to change the label of the textlabel during runtime and change the other controllers as well, i declared two arrays:

Controller P5groupAdcID[][] = new Controller[8][4];
Textlabel P5groupAdcIDtxt[] = new Textlabel[8];

is there a possibilty to overcome this and store all controller handlers in one array?

sojamo Senior Member Offline Posts: 388	Re: controlP5 group event Reply #3 - Dec 9^th, 2008, 6:43am yes. Textlabel extends Controller, therefore it is fairly easy to go with one array, just add the Textlabel to your P5groupAdcID array as 5th element.

this is quite useful to see how to make an array of controls. but how do you define an array of functions?

Code:


int numControls = 10;
for (int i=0; i<numControls; i++) {
   controlP5.addSlider("slider"+i, 0,100, x[i], 10, i*30, 100,15);
}
// ...

// how do you avoid this?  not to mention, you don't know value of numControls...

void slider0(int _x) {
   x[0] = _x;
}
void slider1(int _x) {
   x[1] = _x;
}
void slider2(int _x) {
   x[2] = _x;
}
// ...
