ControlP5 color picker won't resize...

in Contributed Library Questions • 1 year ago

Hi everybody

I've been trying this for a while, but I don't understand if it's me missing something or whatelse....
I'm trying to create a simple GUI where I have a color picker... Problem is the slider are quite small and I would like to augment the HEIGHT of the RGB slider...

controlP5 = new ControlP5(this);
/*
* (floatMin,floatMax,float DefaultValue,int X,int Y,int W,int H)
*/
cp = controlP5.addColorPicker("picker",100,150,sliderW+50,0);

The way it should be is that the last two parameters are for length (siderW+50) and height (0)... But no matter what value I assign to the last it just won't change...

Is it possible or not?
The alternative otherwise would be to use the simple Slider with the size I want; I would have then to change color with the setColor method and so forth for the two other color picker slider (I'm thinking RGB)... Lot of work, so I hope you might help shed some light on the issue...

Thanks in advance

No dice, most of the colorPicker class is hardcoded and there are few specific methods to tweak it.

sooooooo..... the answer is absolutely, without doubt not possible?....

Bear in mind that I've scrolled the reference provided and didn't find any method that suggested it was possible, but I wanted to be extra sure....But is there a way to tweak the Class itself? I'm no Java expert but the designer in me is desperate for a solution....

As far as I know it's not possible with the given class.

Of course it's possible to extend the class and do your own thing, see below.

Code Example

import controlP5.*;
ControlP5 cp5;
MyColorPicker cp;
void setup() {
size(500, 300);
noStroke();
cp5 = new ControlP5(this);
cp = new MyColorPicker(cp5, "hacktastic");
cp.setPosition(50, 50).setColorValue(color(255, 255, 0, 255));
cp.setItemSize(400, 50);
}
void draw() {
background(cp.getColorValue());
}
class MyColorPicker extends ColorPicker {
MyColorPicker(ControlP5 cp5, String theName) {
super(cp5, cp5.getTab("default"), theName, 0, 0, 100, 10);
}
void setItemSize(int w, int h) {
sliderRed.setSize(w, h);
sliderGreen.setSize(w, h);
sliderBlue.setSize(w, h);
sliderAlpha.setSize(w, h);
// you gotta move the sliders as well or they will overlap
sliderGreen.setPosition(PVector.add(sliderGreen.getPosition(), new PVector(0, h-10)));
sliderBlue.setPosition(PVector.add(sliderBlue.getPosition(), new PVector(0, 2*(h-10))));
sliderAlpha.setPosition(PVector.add(sliderAlpha.getPosition(), new PVector(0, 3*(h-10))));
}
}

ok..I didn't know you could extend classes... I guess what the code is trying to do is to create a set of new constructor for the controlP5 class...

this said:
changing the last value (50) of this command will change the height of the white bar on the bottom

cp.setItemSize(400, 50);

super(cp5, cp5.getTab("default"), theName, 0, 0, 100, 10) can only change the length of the three bars (as in controlP5)

I guess the real treat for what I want to do is the setItemSize ().

There is only one problem with this chunk of code and that is in line 31,32,33.... It says when I run it: the function getPosition() does not exist.

(also this line gave error cp.setPosition(50, 50).setColorValue(color(255, 255, 0, 255)); but I just separeted them in two and added cp. before setColorValue and it was ok).

I never used vector in Processing (I'm just beginning to use it) but by looking at the reference .add means " Adds one vector to another" so the slider are vectors; then you're getting its x,y (getPosition) and adding whatever I set in line .24 - 10 to the y...

If I'm right I have to get it's position somehow and it should work?
Let's see.....

Yes. This method does exist in recent versions of ControlP5, apparantly you have an older version installed.

The code I posted is copy-paste runnable for ControlP5 version 0.7.3. and 0.7.4.

Please download the latest version here and try again.
