Make text that is drawn, editable

[cp796]

So I got the colour wheel from cp5 library, and achieved to display the hexcode with text everytime the colour is changed.

This is the code which make the hex code display:
// “C” is the colour on the colour wheel, so whenever the colour is changed it triggers the value of the colour code to change

println(hex(c, 6));
String hex = hex(c, 6);
textvalue =hex;
textSize(14);
fill(255);
text(textvalue, 105, 328);

However this is drawn text. Now I want to make that text to be editable in order for the users to change the value and get the colour they want. Is there a way I can do that?

Thank you in advance

as you already use CP5 try

/**
* ControlP5 Textfield
*
* by Andreas Schlegel, 2012
* www.sojamo.de/libraries/controlp5
*
*/

import controlP5.*;
ControlP5 cp5;

String textValue = "#123456";

void setup() {
  size(200,200);
      
  cp5 = new ControlP5(this);
  
  cp5.addTextfield("input")
     .setPosition(20,100)
     .setSize(100,20)
     .setValue(textValue)
     .setFocus(true)
     .setAutoClear(false)
     .setColor(color(255))
     ;
                 
}

void draw() {
  background(200,200,0);
}


public void input(String theText) {  // automatically receives at ENTER results from controller input
  println("a textfield event for controller 'input' : "+theText);
}

Thank you so much for your reply!

I achieved the first part which was to insert automatically the hex code into the text box.
I have the hex code text in draw in order to update automatically at all times. So when I reference the hex value into the text field I can’t edit it as it updates over and over again with the current value.

Do you have any advice for that? Also do you have any advice, in case eventually I am able to edit the value in the textfield when I press enter to update the hex value with the one I am inserting?

Code I currently have:

//Colour Wheel
import controlP5.*;
ControlP5 cp5;
//Hex Code Mechanism
String textvalue="";
int c = color(100);
void setup() {
  size(1280, 720);
  background(255);

   cp5 = new ControlP5(this);
   
//for Colour Wheel
  cp5 = new ControlP5( this );
  cp5.addColorWheel("c", 20, 80, 220 ).setRGB(color(128, 0, 255));
  noStroke();
}

void draw() {
 cp5.addTextfield("input")

     .setPosition(20,320)

     .setSize(100,20)

     .setValue(hex(c,6))

     .setFocus(true)

     .setAutoClear(false)

     .setColor(color(255))

     ;
//Hex Code Mechanism
  println(hex(c, 6));
  String hex = hex(c, 6);
  textvalue =hex;
  textSize(14);
  fill(255);
  text(textvalue, 105, 328);
}

please repair all your code posting

looks like
```
type or paste code here

why you make the
cp5 declaration inside draw? instead setup?

for what still have a text(); inside draw?

where is your event code??

not sure you wanted to do this?
