Adjustment

open class Adjustment : GLibObject.InitiallyUnowned, AdjustmentProtocol

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 Adjustment type acts as a reference-counted owner of an underlying GtkAdjustment instance. It provides the methods that can operate on this data type through AdjustmentProtocol conformance. Use Adjustment as a strong reference or owner of a GtkAdjustment instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Adjustment instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkAdjustment>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Adjustment instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkAdjustment>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Adjustment instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Adjustment instance.

    Declaration

    Swift

    @inlinable
override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object
