Valuators

Unlike text widgets, valuators keep track of numbers instead of strings. FLTK provides the following valuators:

• Fl_Counter - A widget with arrow buttons that shows the current value

• Fl_Dial - A round knob

• Fl_Roller - An SGI-like dolly widget

• Fl_Scrollbar - A standard scrollbar widget

• Fl_Slider - A scrollbar with a knob

• Fl_Value_Slider - A slider that shows the current value

The value() method gets and sets the current value of the widget. The minimum() and maximum() methods set the range of values that are reported by the widget.
