#### Fl_Spinner::Fl_Spinner(int x, int y, int w, int h, const char *label = 0)

Creates a new `Fl_Spinner` widget using the given position, size, and label string.

#### virtual Fl_Spinner::~Fl_Spinner()

Destroys the widget and any value associated with it.

#### void format(const char *f)
const char *format()

Sets or returns the format string for the value.

#### void maximum(double m)
double maximum() const

Sets or returns the maximum value of the widget.

#### void minimum(double m)
double minimum() const

Sets or returns the minimum value of the widget.

#### void range(double minval, double maxval)

Sets the minimum and maximum values for the widget.

#### void step(double s)
double step() const

Sets or returns the amount to change the value when the user clicks a button. Before setting `step` to a non-integer value, the spinner `type()` should be changed to floating point.

#### void textcolor(Fl_Color c)
Fl_Color textcolor() const

Sets or returns the color of the text in the input field.

#### void textfont(uchar f)
uchar textfont() const

Sets or returns the font of the text in the input field.

#### void textsize(uchar s)
uchar textsize() const

Sets or returns the size of the text in the input field.

#### void type(uchar s)
uchar type() const

Sets or returns the numeric representation in the input field. Valid values are `FL_INT_INPUT` and `FL_FLOAT_INPUT`. The first form also changes the `format()` template. Please note that `type` is not a virtual function. Setting a new spinner type via a superclass pointer will not work.

#### void Fl_Spinner::value(double v)
double Fl_Spinner::value() const

Sets or returns the current value of the widget. Before setting `value` to a non-integer value, the spinner `type()` should be changed to floating point.
