a momentary solution for me was:
myLabel.setText(String.valueOf(myKnob.getValueI()));

...if useful to someone...

Davide.

Is it my fault?

Difficult to say without seeing the code, but I think in this case the answer is - yes

Internally the GKnob stores its current state as a float in the range 0.0 - 1.0 inclusive. The user can use setLimits to define the range of values to be returned.

To cope with both float and integer ranges the GKnob has 2 methods to retrive a value

knob.getValueF(); // get the value as a float
knob.getValueI(); // get the value as an int

If you use these methods before using setLimits then you will get either

• a float in the range 0.0 to 1.0 inclusive with getValueF
• an int which is either 0 or 1 with getValueI

HTH

mmmm...

Try this and tell me what's wrong inside, please, because for me it doesn't work.

1. import g4p_controls.*;
   
   GKnob   kb;
   GLabel  lb;
   
   void setup() {
     size(200, 200);
     kb = new GKnob(this, 10,10,100,100,0.7f);
     kb.setNumberFormat(GKnob.INTEGER);
     kb.setTurnMode(GKnob.CTRL_ANGULAR);
     kb.setLimits(10, 0, 50);
     kb.setNbrTicks(6);
     lb = new GLabel(this, 10,130,100,30,kb.getValueS());
   }
   
   void draw() {
     background(180);
     lb.setText(kb.getValueS());
   }
   

Thanks for posting the code this proves that there was a bug in the getValueS() method. As there was no code in your original post I was testing the wrong methods.

I have found and removed the bug so this fix will be in the next release of G4P.

So it was not your fault it was my fault - sorry about that.

The code below is my tempory fix

1. import g4p_controls.*;
2. 
   
3. GKnob   kb;
4. GLabel  lb;
5. 
   
6. void setup() {
7.   size(200, 200);
8.   kb = new GKnob(this, 10,10,100,100,0.7f);
9.   kb.setNumberFormat(GKnob.INTEGER);
10.   kb.setTurnMode(GKnob.CTRL_ANGULAR);
11.   kb.setLimits(10, 0, 50);
12.   kb.setNbrTicks(6);
13.   lb = new GLabel(this, 10,130,100,30,kb.getValueS());
14. }
15. 
    
16. void draw() {
17.   background(180);
18. }
19. 
    
20. public void handleKnobEvents(GValueControl knob, GEvent event) {
21.   lb.setText("" + kb.getValueI());
22. }

Thanks for your support.

Thank you for keeping alive your library!

i'll be grateful if you'll advise also here for the new release.

Davide.

Hi, finally I could try the fix and I can confirm it just works!

@quarks:
By the way, i've a suggestion that, of course, goes towards my personal interest... I need to set up a grid of say 8 * 20 TextFields. and maybe also have the oppurtinity of adding an extra line every time an event occours.
By now I can do it with sequentially add GTextFields, but is it in your interest to create something like a GGrid with options like Columns, Rows,HGap,VGap and maybe also the getValueI, getValueF and getValueS methods?

it could be a convenient way to add simple datacells, without having to read an excell file or similar.

Hi, Davide.
