//: Retrieve an integer or floating-point number from the user.
//- A {\class Gtk::SpinButton} is an ideal way to allow the user to set the value of
//- some attribute. Rather than having to directly type a number into a {Gtk::Entry::},
//- {\class Gtk::SpinButton} allows the user to click on one of two arrows to
//- increment or decrement the displayed value. A value can still be typed in, with the
//- bonus that it can be checked to ensure it is in a given range.
//-
//- The main properties of a {\class Gtk::SpinButton} are through a {Gtk::Adjustment::}.
//- See the {Gtk::Adjustment::} section for more details about an adjustment's
//- properties.
//-
//- The {Gtk::Adjustment::} of a spin button can be set or retrieved with a call to
//- {set_adjustment()} or {get_adjustment()}, respectively.
//-
//- The number of digits after the decimal point of a spin button can be altered with
//- {set_digits()}.
//-
//- To retrieve values from a spin button, use {get_value_as_float()} if you require
//- a floating point number, or {get_value_as_int()} if you require an integer.
//-
//- To set the value of a {\class Gtk::SpinButton}, use {set_value()}. To change the
//- update behaviour of a spin button, use {set_update_policy()}.
//-
//- When a spin button reaches it's upper or lower limit, it can either stop spinning,
//- or wrap around and continue spinning from the opposite limit. For example, if five
//- is the upper limit and the lower limit is zero, upon reaching the value five, the
//- spin button can change it's value back to zero and continue spinning upwards. This
//- behaviour is set with {set_wrap()}.
//-
//- A border around a spin button's arrows can be created using {set_shadow_type()}.
//-
//- A number may be entered that is invalid, given a spin button's range. An erroneous
//- number can be corrected as soon as the spin button is 'activated' using
//- {set_snap_to_ticks()}, which will alter the current value to the nearest step
//- increment. (See {Gtk::Adjustment::} for step increments).
//-
//- Because a spin contains a {Gtk::Entry::}, alphabetic characters may be entered.
//- These can be ignored by using {set_numeric()} with a value of TRUE. Then only
//- numeric values, '-' and a decimal point will be accepted.
//-
//- To manually increment or decrement the spin button, use {spin()}, and to force an
//- update (refresh), use {update()}.
