FormerSlider<TForm extends FormerForm> class
A normal Slider that:
- controls the given field
- follows whether the form is enabled (can override in constructor)
Slider returns a double when changed. When an int field is passed to FormerSlider, the double is truncated to an int with num.toInt. No special casting is done when it is a num field.
TForm
must be specified in order for FormerSlider to find the correct
form in context.
