  Whether to activate the default widget when the spin button is activated.
• public Adjustment adjustment { get; set; }
  The adjustment that holds the value of the spin button.
• public double climb_rate { get; set; }
  The acceleration rate when you hold down a button or key.
• public uint digits { get; set; }
  The number of decimal places to display.
• public bool numeric { get; set; }
  Whether non-numeric characters should be ignored.
• public bool snap_to_ticks { get; set; }

• public SpinButtonUpdatePolicy update_policy { get; set; }
  Whether the spin button should update always, or only when the value is acceptable.
• public double value { get; set; }

Creation methods:

• public SpinButton (Adjustment? adjustment, double climb_rate, uint digits)
  Creates a new `GtkSpinButton`.
• public SpinButton.with_range (double min, double max, double step)
  Creates a new `GtkSpinButton` with the given properties.

Methods:

• public void configure (Adjustment? adjustment, double climb_rate, uint digits)
  Changes the properties of an existing spin button.
• public bool get_activates_default ()
  Retrieves the value set by [method@Gtk.
• public unowned Adjustment get_adjustment ()
  Get the adjustment associated with a `GtkSpinButton`.
• public double get_climb_rate ()
  Returns the acceleration rate for repeated changes.
• public uint get_digits ()
  Fetches the precision of this.
• public void get_increments (out double step, out double page)
  Gets the current step and page the increments used by this.
• public bool get_numeric ()
  Returns whether non-numeric text can be typed into the spin button.
• public void get_range (out double min, out double max)
  Gets the range allowed for this.
• public bool get_snap_to_ticks ()
  Returns whether the values are corrected to the nearest step.
• public SpinButtonUpdatePolicy get_update_policy ()
  Gets the update behavior of a spin button.
• public double get_value ()
  Get the value in the this.
• public int get_value_as_int ()
  Get the value this represented as an integer.
• public bool get_wrap ()
  Returns whether the spin button’s value wraps around to the opposite limit when the upper or lower limit of the range is exceeded.
• public void set_activates_default (bool activates_default)
  Sets whether activating the spin button will activate the default widget for the window containing the spin button.
• public void set_adjustment (Adjustment adjustment)
  Replaces the `GtkAdjustment` associated with this .
• public void set_climb_rate (double climb_rate)
  Sets the acceleration rate for repeated changes when you hold down a button or key.
• public void set_digits (uint digits)
  Set the precision to be displayed by this.
• public void set_increments (double step, double page)
  Sets the step and page increments for spin_button.
• public void set_numeric (bool numeric)
  Sets the flag that determines if non-numeric text can be typed into the spin button.
• public void set_range (double min, double max)
  Sets the minimum and maximum allowable values for this.
• public void set_snap_to_ticks (bool snap_to_ticks)
  Sets the policy as to whether values are corrected to the nearest step increment when a spin button is activated after providing an invalid value.
• public void set_update_policy (SpinButtonUpdatePolicy policy)
  Sets the update behavior of a spin button.
• public void set_value (double value)
  Sets the value of this.
• public void set_wrap (bool wrap)
  Sets the flag that determines if a spin button value wraps around to the opposite limit when the upper or lower limit of the range is exceeded.
• public void spin (SpinType direction, double increment)
  Increment or decrement a spin button’s value in a specified direction by a specified amount.
• public void update ()
  Manually force an update of the spin button.

Signals:

• public signal void activate ()
  Emitted when the spin button is activated.
• public signal void change_value (ScrollType scroll)
  Emitted when the user initiates a value change.
• public signal int input (out double new_value)
  Emitted to convert the users input into a double value.
• public signal bool output ()
  Emitted to tweak the formatting of the value for display.
• public signal void value_changed ()
  Emitted when the value is changed.
• public signal void wrapped ()
  Emitted right after the spinbutton wraps from its maximum to its minimum value or vice-versa.
