RangeRef

public struct RangeRef : RangeProtocol, GWeakCapturing

GtkRange is the common base class for widgets which visualize an adjustment.

Widgets that are derived from GtkRange include [classGtk.Scale] and [classGtk.Scrollbar].

Apart from signals for monitoring the parameters of the adjustment, GtkRange provides properties and methods for setting a “fill level” on range widgets. See [methodGtk.Range.set_fill_level].

The RangeRef type acts as a lightweight Swift reference to an underlying GtkRange instance. It exposes methods that can operate on this data type through RangeProtocol conformance. Use RangeRef only as an unowned reference to an existing GtkRange instance.

  • ptr 
    Untyped pointer to the underlying `GtkRange` instance.

    For type-safe access, use the generated, typed pointer range_ptr property instead.
