When I have a Slider set to LinearBar, I can change the color of the filled part with Slider::trackColourId, and the outline with Slider::textBoxOutlineColourId, but does anything control the color of the non-filled part?
In other words, if you click in the middle, the part to the left will be filled with trackColourId. But what about the part on the right? It seems to be just showing whatever the component’s background color is.
