Invisible

open class Invisible : Widget, InvisibleProtocol

The GtkInvisible widget is used internally in GTK+, and is probably not very useful for application developers.

It is used for reliable pointer grabs and selection handling in the code for drag-and-drop.

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

    Declaration

    Swift

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

    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 Invisible instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • 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 Invisible 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 Invisible instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

    Parameters

    op
