procedure Set_Adjustment
(The_Range : access Gtk_Range_Record;
Adjustment : access Gtk.Adjustment.Gtk_Adjustment_Record'Class);
-- Sets the adjustment to be used as the "model" object for this range
-- widget. The adjustment indicates the current range value, the minimum
-- and maximum range values, the step/page increments used for keybindings
-- and scrolling, and the page size. The page size is normally 0 for
-- Gtk.Scale.Gtk_Scale and nonzero for Gtk.Scrollbar.Gtk_Scrollbar, and
-- indicates the size of the visible area of the widget being scrolled. The
-- page size affects the size of the scrollbar slider.
-- "adjustment": a Gtk.Adjustment.Gtk_Adjustment
function Get_Fill_Level

procedure Set_Fill_Level
(The_Range : access Gtk_Range_Record;
Fill_Level : Gdouble);
-- Set the new position of the fill level indicator. The "fill level" is
-- probably best described by its most prominent use case, which is an
-- indicator for the amount of pre-buffering in a streaming media player.
-- In that use case, the value of the range would indicate the current play
-- position, and the fill level would be the position up to which the
-- file/stream has been downloaded. This amount of prebuffering can be
-- displayed on the range's trough and is themeable separately from the
-- trough. To enable fill level display, use
-- Gtk.GRange.Set_Show_Fill_Level. The range defaults to not showing the
-- fill level. Additionally, it's possible to restrict the range's slider
-- position to values which are smaller than the fill level. This is
-- controller by Gtk.GRange.Set_Restrict_To_Fill_Level and is by default
-- enabled.

-- Signals --

-- The following new signals are defined for this widget:

-- "adjust-bounds"
-- procedure Handler
-- (Self : access Gtk_Range_Record'Class;
-- Object : Gdouble);
--
-- "change-value"
-- function Handler
-- (Self : access Gtk_Range_Record'Class;
-- Scroll : Gtk.Enums.Gtk_Scroll_Type;
-- Value : Gdouble) return Boolean;
-- -- "scroll": the type of scroll action that was performed
-- -- "value": the new value resulting from the scroll action
-- The ::change-value signal is emitted when a scroll action is performed
-- on a range. It allows an application to determine the type of scroll
-- event that occurred and the resultant new value. The application can
-- handle the event itself and return True to prevent further processing.
-- Or, by returning False, it can pass the event to other handlers until
-- the default GTK+ handler is reached. The value parameter is unrounded.
-- An application that overrides the ::change-value signal is responsible
-- for clamping the value to the desired number of decimal digits; the
-- default GTK+ handler clamps the value based on
-- Gtk.GRange.Gtk_Range:round_digits. It is not possible to use delayed
-- update policies in an overridden ::change-value handler.
--
-- "move-slider"
-- procedure Handler
-- (Self : access Gtk_Range_Record'Class;
-- Step : Gtk.Enums.Gtk_Scroll_Type);
-- -- "step": how to move the slider
-- Virtual function that moves the slider. Used for keybindings.
--
-- "value-changed"
-- procedure Handler (Self : access Gtk_Range_Record'Class);
-- Emitted when the range value changes.
