Properties:

• public Adjustment adjustment { get; set construct; }
  The adjustment that is controlled by the range.
• public double fill_level { get; set; }
  The fill level (e.
• public bool inverted { get; set; }
  If true, the direction in which the slider moves is inverted.
• public bool restrict_to_fill_level { get; set; }
  Controls whether slider movement is restricted to an upper boundary set by the fill level.
• public int round_digits { get; set; }
  The number of digits to round the value to when it changes.
• public bool show_fill_level { get; set; }
  Controls whether fill level indicator graphics are displayed on the trough.

Creation methods:

• protected Range ()

Methods:

• public unowned Adjustment get_adjustment ()
  Get the adjustment which is the “model” object for `GtkRange`.
• public double get_fill_level ()
  Gets the current position of the fill level indicator.
• public bool get_flippable ()
  Gets whether the `GtkRange` respects text direction.
• public bool get_inverted ()
  Gets whether the range is inverted.
• public virtual Border get_range_border ()
• public Rectangle get_range_rect ()
  This function returns the area that contains the range’s trough, in coordinates relative to this's origin.
• public bool get_restrict_to_fill_level ()
  Gets whether the range is restricted to the fill level.
• public int get_round_digits ()
  Gets the number of digits to round the value to when it changes.
• public bool get_show_fill_level ()
  Gets whether the range displays the fill level graphically.
• public void get_slider_range (out int slider_start, out int slider_end)
  This function returns sliders range along the long dimension, in widget->window coordinates.
• public bool get_slider_size_fixed ()
  This function is useful mainly for `GtkRange` subclasses.
• public double get_value ()
  Gets the current value of the range.
• public void set_adjustment (Adjustment adjustment)
  Sets the adjustment to be used as the “model” object for the `GtkRange`
• public void set_fill_level (double fill_level)
  Set the new position of the fill level indicator.
• public void set_flippable (bool flippable)
  Sets whether the `GtkRange` respects text direction.
• public void set_increments (double step, double page)
  Sets the step and page sizes for the range.
• public void set_inverted (bool setting)
  Sets whether to invert the range.
• public void set_range (double min, double max)
  Sets the allowable values in the `GtkRange`.
• public void set_restrict_to_fill_level (bool restrict_to_fill_level)
  Sets whether the slider is restricted to the fill level.
• public void set_round_digits (int round_digits)
  Sets the number of digits to round the value to when it changes.
• public void set_show_fill_level (bool show_fill_level)
  Sets whether a graphical fill level is show on the trough.
• public void set_slider_size_fixed (bool size_fixed)
  Sets whether the range’s slider has a fixed size, or a size that depends on its adjustment’s page size.
• public void set_value (double value)
  Sets the current value of the range.

Signals:

• public virtual signal void adjust_bounds (double new_value)
  Emitted before clamping a value, to give the application a chance to adjust the bounds.
• public virtual signal bool change_value (ScrollType scroll, double new_value)
  Emitted when a scroll action is performed on a range.
• public virtual signal void move_slider (ScrollType scroll)
  Virtual function that moves the slider.
• public virtual signal void value_changed ()
  Emitted when the range value changes.
