Memory-managed wrapper type.

Type class for types which can be safely cast to Range, for instance with toRange.

Cast to Range, for types for which this is known to be safe. For general casts, use castTo.

A convenience alias for Nothing :: Maybe Range.

Get the Adjustment which is the “model” object for Range. See rangeSetAdjustment for details. The return value does not have a reference added, so should not be unreferenced.

Gets the current position of the fill level indicator.

Since: 2.12

Gets the value set by rangeSetFlippable.

Since: 2.18

Gets the value set by rangeSetInverted.

Gets the sensitivity policy for the stepper that points to the 'lower' end of the GtkRange’s adjustment.

This function is useful mainly for Range subclasses.

Since: 2.20

This function is useful mainly for Range subclasses.

See rangeSetSliderSizeFixed.

Since: 2.20

Gets the sensitivity policy for the stepper that points to the 'upper' end of the GtkRange’s adjustment.

Since: 2.10

Gets the current value of the range.

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 Scale and nonzero for Scrollbar, and indicates the size of the visible area of the widget being scrolled. The page size affects the size of the scrollbar slider.

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 rangeSetShowFillLevel. 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 rangeSetRestrictToFillLevel and is by default enabled.

Since: 2.12

If a range is flippable, it will switch its direction if it is horizontal and its direction is TextDirectionRtl.

See widgetGetDirection.

Since: 2.18

Sets the step and page sizes for the range. The step size is used when the user clicks the Scrollbar arrows or moves Scale via arrow keys. The page size is used for example when moving via Page Up or Page Down keys.

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.

Sets the sensitivity policy for the stepper that points to the 'lower' end of the GtkRange’s adjustment.

Since: 2.10

Sets the minimum size of the range’s slider.

This function is useful mainly for Range subclasses.

Since: 2.20

Sets the allowable values in the 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.)

Sets whether the slider is restricted to the fill level. See rangeSetFillLevel for a general description of the fill level concept.

Since: 2.12

Sets the number of digits to round the value to when it changes. See changeValue.

Since: 2.24

Sets whether a graphical fill level is show on the trough. See rangeSetFillLevel for a general description of the fill level concept.

Since: 2.12

Sets whether the range’s slider has a fixed size, or a size that depends on its adjustment’s page size.

This function is useful mainly for Range subclasses.

Since: 2.20

Sets the sensitivity policy for the stepper that points to the 'upper' end of the GtkRange’s adjustment.

Since: 2.10

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 valueChanged signal if the value changes.

Type for the callback on the (unwrapped) C side.

The changeValue 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 GtkRange[changeValue](#signal:changeValue) signal is responsible for clamping the value to the desired number of decimal digits; the default GTK+ handler clamps the value based on Range:round-digits.
