Toplevel

open class Toplevel : Surface, ToplevelProtocol

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

A GdkToplevel is a freestanding toplevel surface.

The GdkToplevel interface provides useful APIs for interacting with the windowing system, such as controlling maximization and size of the surface, setting icons and transient parents for dialogs.

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

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

    Declaration

    Swift

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

    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 Toplevel instance.

    Declaration

    Swift

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

    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 Toplevel 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 Toplevel instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
