AdjustmentRef

public struct AdjustmentRef : AdjustmentProtocol, GWeakCapturing

GtkAdjustment is a model for a numeric value.

The `GtkAdjustment has an associated lower and upper bound. It also contains step and page increments, and a page size.

Adjustments are used within several GTK widgets, including [classGtk.SpinButton], [classGtk.Viewport], [classGtk.Scrollbar] and [classGtk.Scale].

The GtkAdjustment object does not update the value itself. Instead it is left up to the owner of the GtkAdjustment to control the value.

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

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

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