Kob value display when hover or drag mouse

General JUCE discussion
1

Hi

I´ve written the code in Matalab and then compile in C++ for Juce framework. This is a very simple code but reproduce the graphical issue I´m experiencing. I´ve just kept relevant lines (if not let me know).

I need to display the value of the knob when mouse hover or drag its position, but slider. setPopupDisplayEnabled (true,true,this) doesn´t work here as it is. Surely I´m wrongly referencing the component(or even placing wrong), but as my C++skills are really low, that´s why I´m here.
As it is written, it display de name of the knob and I know how to trun off this notification, but I don´t knwo how to replace for the value.

This graphical topic is the last thing to complete my project, I´d really appreciated if someone can help me in solving this out.

Thanks
Pablo
