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.
-
Untyped pointer to the underlying `GtkRange` instance.
For type-safe access, use the generated, typed pointer
range_ptr
property instead.Declaration
