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.
