How to make Slider's PopupDisplay always visible?

I know you can make appear a popupDisplay of a slider using setPopupDisplayEnabled() , but there is a way to make it always visible? not only when when mouse is dragging or hovering.

Thanks in advance!

Isn’t that just the same as having the text box visible?

I have customized too much the popupDisplay, and it can appers outside the bounds of the slider. That’s why I want to make always visible the popupDisplay instead of use the TextBox.
