Subprograms & Entries

Get_Type

function Get_Type return Glib.GType;

Get_Adjustment

function Get_Adjustment 
(The_Range: access Gtk_Range_Record) return Gtk.Adjustment.Gtk_Adjustment;

Set_Adjustment

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

Get_Fill_Level

function Get_Fill_Level 
(The_Range: access Gtk_Range_Record) return Gdouble;

Set_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. Since: gtk+ 2.12 "fill_level": the new position of the fill level indicator

Get_Flippable

function Get_Flippable 
(The_Range: access Gtk_Range_Record) return Boolean;

Set_Flippable

procedure Set_Flippable 
(The_Range: access Gtk_Range_Record;
Flippable: Boolean);
If a range is flippable, it will switch its direction if it is horizontal and its direction is %GTK_TEXT_DIR_RTL. See Gtk.Widget.Get_Direction. Since: gtk+ 2.18 "flippable": True to make the range flippable

Get_Inverted

function Get_Inverted 
(The_Range: access Gtk_Range_Record) return Boolean;

Set_Inverted

procedure Set_Inverted 
(The_Range: access Gtk_Range_Record;
Setting: Boolean);
Ranges normally move from lower to higher values as the slider moves from top to bottom or left to right. Inverted ranges have higher values at the top or on the right rather than on the bottom or left. "setting": True to invert the range

Get_Lower_Stepper_Sensitivity

function Get_Lower_Stepper_Sensitivity 
(The_Range: access Gtk_Range_Record) return Gtk.Enums.Gtk_Sensitivity_Type;

Set_Lower_Stepper_Sensitivity

procedure Set_Lower_Stepper_Sensitivity 
(The_Range: access Gtk_Range_Record;
Sensitivity: Gtk.Enums.Gtk_Sensitivity_Type);
Sets the sensitivity policy for the stepper that points to the 'lower' end of the GtkRange's adjustment. Since: gtk+ 2.10 "sensitivity": the lower stepper's sensitivity policy.

Get_Min_Slider_Size

function Get_Min_Slider_Size 
(The_Range: access Gtk_Range_Record) return Gint;

Set_Min_Slider_Size

procedure Set_Min_Slider_Size 
(The_Range: access Gtk_Range_Record;
Min_Size: Boolean);
Sets the minimum size of the range's slider. This function is useful mainly for Gtk.GRange.Gtk_Range subclasses. Since: gtk+ 2.20 "min_size": The slider's minimum size

Get_Range_Rect

procedure Get_Range_Rect 
(The_Range: access Gtk_Range_Record;
Range_Rect: out Gdk.Rectangle.Gdk_Rectangle);
This function returns the area that contains the range's trough and its steppers, in widget->window coordinates. This function is useful mainly for Gtk.GRange.Gtk_Range subclasses. Since: gtk+ 2.20 "range_rect": return location for the range rectangle

Get_Restrict_To_Fill_Level

function Get_Restrict_To_Fill_Level 
(The_Range: access Gtk_Range_Record) return Boolean;

Set_Restrict_To_Fill_Level

procedure Set_Restrict_To_Fill_Level 
(The_Range: access Gtk_Range_Record;
Restrict_To_Fill_Level: Boolean);
Sets whether the slider is restricted to the fill level. See Gtk.GRange.Set_Fill_Level for a general description of the fill level concept. Since: gtk+ 2.12 "restrict_to_fill_level": Whether the fill level restricts slider movement.

Get_Round_Digits

function Get_Round_Digits 
(The_Range: access Gtk_Range_Record) return Gint;

Set_Round_Digits

procedure Set_Round_Digits 
(The_Range: access Gtk_Range_Record;
Round_Digits: Gint);
Sets the number of digits to round the value to when it changes. See Gtk.GRange.Gtk_Range::change-value. Since: gtk+ 2.24 "round_digits": the precision in digits, or -1

Get_Show_Fill_Level

function Get_Show_Fill_Level 
(The_Range: access Gtk_Range_Record) return Boolean;

Set_Show_Fill_Level

procedure Set_Show_Fill_Level 
(The_Range: access Gtk_Range_Record;
Show_Fill_Level: Boolean);
Sets whether a graphical fill level is show on the trough. See Gtk.GRange.Set_Fill_Level for a general description of the fill level concept. Since: gtk+ 2.12 "show_fill_level": Whether a fill level indicator graphics is shown.

Get_Slider_Range

procedure Get_Slider_Range 
(The_Range: access Gtk_Range_Record;
Slider_Start: out Gint;
Slider_End: out Gint);
This function returns sliders range along the long dimension, in widget->window coordinates. This function is useful mainly for Gtk.GRange.Gtk_Range subclasses. Since: gtk+ 2.20 "slider_start": return location for the slider's start, or null "slider_end": return location for the slider's end, or null

Get_Slider_Size_Fixed

function Get_Slider_Size_Fixed 
(The_Range: access Gtk_Range_Record) return Boolean;

Set_Slider_Size_Fixed

procedure Set_Slider_Size_Fixed 
(The_Range: access Gtk_Range_Record;
Size_Fixed: Boolean);
Sets whether the range's slider has a fixed size, or a size that depends on it's adjustment's page size. This function is useful mainly for Gtk.GRange.Gtk_Range subclasses. Since: gtk+ 2.20 "size_fixed": True to make the slider size constant

Get_Update_Policy

function Get_Update_Policy 
(The_Range: access Gtk_Range_Record) return Gtk.Enums.Gtk_Update_Type;

Set_Update_Policy

procedure Set_Update_Policy 
(The_Range: access Gtk_Range_Record;

Set_Value

procedure Set_Value 
(The_Range: access Gtk_Range_Record;
Value: Gdouble);
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. The range emits the Gtk.GRange.Gtk_Range::value-changed signal if the value changes. "value": new value of the range

Set_Increments

procedure Set_Increments 
(The_Range: access Gtk_Range_Record;
Step: Gdouble;
Page: Gdouble);

Set_Range

procedure Set_Range 
(The_Range: access Gtk_Range_Record;
Min: Gdouble;
Max: Gdouble);
Sets the allowable values in the Gtk.GRange.Gtk_Range, and clamps the range value to be between Min and Max. (If the range has a non-zero page size, it is clamped between Min and Max - page-size.) "min": minimum range value "max": maximum range value
