B4J Question setColor event of Color Picker is not working

Referring to this post by @Erel: https://www.b4x.com/android/forum/threads/bccolorpicker-nice-color-picker.114368/
In the example given, after downloading the BCColorPicker.b4xlib, placing it in the additional libraries folder and loading it in the IDE
to my surprise, the 'Panel' color is neither changed nor the event is invoked (by logging ColorValue)
What is going on?

I guess you didn't click the button to confirm the color

Yes. I did not know that I should click that button to invoke the event. Thanks a lot

B4X:

Dim p As Paint=fx.Colors.From32Bit(ColorValue)

I could figure it out, converting an Int Color value to javafx.scene.paint.Paint:

B4X:

Sub GetARGB(Color As Int) As Object
    Private res(4) As Int
    res(0) = Bit.UnsignedShiftRight(Bit.And(Color, 0xff000000), 24)
    res(1) = Bit.UnsignedShiftRight(Bit.And(Color, 0xff0000), 16)
    res(2) = Bit.UnsignedShiftRight(Bit.And(Color, 0xff00), 8)
    res(3) = Bit.And(Color, 0xff)
    Dim paint As Object= fx.Colors.ARGB(res(0),res(1),res(2),res(3))

    Return paint
End Sub

Thanks anyway.
