ControlP5 - Setting the text of a label

in Contributed Library Questions • 3 years ago

I am creating some labels in a for loop

controlP5.addTextlabel("label"+i+j,table[j][i],10,10);

But, how can I reference these, to change the labels again?

I have tried
controlP5.controller("label"+i+j).setLabel("Text");

and
controlP5.controller("label"+i+j).setValueLabel("Text");

but neither work.

There is also a controller.stringValue()
but this doesnt take an argument, so not sure how to use!

Many thanks,

RD

I shouldn't have taken you at your word :(
I wasted time putting labels into an ArrayList and changing their value from a direct reference when in actual fact setValueLabel() seems to work just fine:

import controlP5.*;
ControlP5 controlP5;
void setup() {
size(200,300);
controlP5 = new ControlP5(this);
for(int i=0; i< 5; i++){
controlP5.addTextlabel("label"+i,"label "+i,10,30+i*30);
}
}
void draw() {
background(0);
}
void mousePressed() {
for(int i=0; i< 5; i++){
controlP5.controller("label"+i).setValueLabel("foo " + i);
}
}

Actually thinking about it the problem may be down to how you name your labels. If i+j resolves as the sum of the two numbers - rather than concatenating them - then your labels don't have unique names.

Thanks blindfish.

I was convinced I was right. You actually helped me realise I had another bug in my code!

Sorry to waste your time on such a basic question.

Thanks again.
