Properties:

• public Adjustment adjustment { get; set construct; }
• public double fill_level { get; set; }
  The fill level (e.
• public bool inverted { get; set; }
• public SensitivityType lower_stepper_sensitivity { get; set; }
• public bool restrict_to_fill_level { get; set; }
  The restrict-to-fill-level property 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, or -1.
• public bool show_fill_level { get; set; }
  The show-fill-level property controls whether fill level indicator graphics are displayed on the trough.
• public SensitivityType upper_stepper_sensitivity { get; set; }

Creation methods:

• protected Range ()

Methods:

• public unowned Adjustment get_adjustment ()
  Get the Adjustment which is the “model” object for Range.
• public double get_fill_level ()
  Gets the current position of the fill level indicator.
• public bool get_flippable ()
  Gets the value set by set_flippable.
• public bool get_inverted ()
  Gets the value set by set_inverted.
• public SensitivityType get_lower_stepper_sensitivity ()
  Gets the sensitivity policy for the stepper that points to the 'lower' end of the GtkRange’s adjustment.
• public int get_min_slider_size ()
  This function is useful mainly for Range subclasses.
• public virtual Border get_range_border ()
• public Rectangle get_range_rect ()
  This function returns the area that contains the range’s trough and its steppers, in widget->window coordinates.
• public virtual void get_range_size_request (Orientation orientation, out int minimum, out int natural)
• 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 Range subclasses.
• public SensitivityType get_upper_stepper_sensitivity ()
  Gets the sensitivity policy for the stepper that points to the 'upper' end of the GtkRange’s adjustment.
• 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 this range widget.
• public void set_fill_level (double fill_level)
  Set the new position of the fill level indicator.
• public void set_flippable (bool flippable)
  If a range is flippable, it will switch its direction if it is horizontal and its direction is gtk_text_dir_rtl.
• public void set_increments (double step, double page)
  Sets the step and page sizes for the range.
• public void set_inverted (bool setting)
  Ranges normally move from lower to higher values as the slider moves from top to bottom or left to right.
• public void set_lower_stepper_sensitivity (SensitivityType sensitivity)
  Sets the sensitivity policy for the stepper that points to the 'lower' end of the GtkRange’s adjustment.
• public void set_min_slider_size (int min_size)
  Sets the minimum size of the range’s slider.
• public void set_range (double min, double max)
  Sets the allowable values in the Range, and clamps the range value to be between min and max.
• 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_upper_stepper_sensitivity (SensitivityType sensitivity)
  Sets the sensitivity policy for the stepper that points to the 'upper' end of the GtkRange’s adjustment.
• public void set_value (double value)
  Sets the current value of the range; if the value is outside the minimum or maximum range values, it will be clamped to fit inside them.

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)
  The change_value signal is 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.
