Visual

open class Visual : GLibObject.Object, VisualProtocol

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

A GdkVisual contains information about a particular visual.

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

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

    Declaration

    Swift

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

    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 Visual instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object
