A Slider is a wrapper around a QSlider.<br/>
There are two variants: SliderInt and SliderDouble, for working with signed integers and doubles, respectively.<br/>
They add tooltip functionality, as well as conversion to the proper data types (int and double).

// Here's an example that creates a slider and sets the hover/tooltip indicator to display as a percentage
SliderInt* sliderInt = new SliderInt();
sliderInt->setRange(0, 100);
sliderInt->setToolTipFormatting("", "%");

// Assuming you've created a slider already (either in code or via .ui file), give it the mid point style like this:
Slider::applyMidPointStyle(sliderInt);

// Disable it like this:
sliderInt->setEnabled(false);

// Here's an example of creating a SliderDouble and setting it up:
SliderDouble* sliderDouble = new SliderDouble();
double min = -10.0;
double max = 10.0;
int numSteps = 21;
sliderDouble->setRange(min, max, numSteps);
sliderDouble->setValue(0.0);

// Listen for changes; same format for SliderInt as SliderDouble
connect(sliderDouble, &SliderDouble::valueChanged, sliderDouble, [sliderDouble](double newValue){
