setPopupDisplayEnabled() you can chose whether to show the Popup Display when the slider is dragged or when the mouse is over the component, but in no way you can show the popup display only when you use the wheel to set the value of a slider and not when the mouse pointer is just over the component (which in most cases conflicts with the ToolTip window).
The only solution I have found is to modify the juce_Slider.cpp file at the
Pimpl::mouseWheelMove() function ad add these lines after the setValue() call:
if (popupDisplay == nullptr) showPopupDisplay(); if (popupDisplay != nullptr && popupHoverTimeout != -1) popupDisplay->startTimer(popupHoverTimeout);
But, honestly, I hate to modify the source code of a library, mostly because at the next update I must remember to modify the file again.
Can somebody suggest an equivalent method to detect the mouse wheel movement without having to override the entire function and invoke
