BinProtocol

public protocol BinProtocol : ContainerProtocol

The GtkBin widget is a container with just one child. It is not very useful itself, but it is useful for deriving subclasses, since it provides common code needed for handling a single child widget.

Many GTK+ widgets are subclasses of GtkBin, including GtkWindow, GtkButton, GtkFrame, GtkHandleBox or GtkScrolledWindow.

The BinProtocol protocol exposes the methods and properties of an underlying GtkBin instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see Bin. Alternatively, use BinRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • ptr

    Untyped pointer to the underlying GtkBin instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer! { get }
  • bin_ptr Default implementation

    Typed pointer to the underlying GtkBin instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GtkBin instance.

    Declaration

    Swift

    var bin_ptr: UnsafeMutablePointer<GtkBin>! { get }
  • Required Initialiser for types conforming to BinProtocol

    Declaration

    Swift

    init(raw: UnsafeMutableRawPointer)

Bin Class

  • Bind a BinPropertyName source property to a given target object.

    Declaration

    Swift

    @discardableResult
    @inlinable
    func bind<Q, T>(property source_property: BinPropertyName, to target: T, _ target_property: Q, flags f: BindingFlags = .default, transformFrom transform_from: @escaping GLibObject.ValueTransformer = { $0.transform(destValue: $1) }, transformTo transform_to: @escaping GLibObject.ValueTransformer = { $0.transform(destValue: $1) }) -> BindingRef! where Q : PropertyNameProtocol, T : ObjectProtocol

    Parameters

    source_property

    the source property to bind

    target

    the target object to bind to

    target_property

    the target property to bind to

    flags

    the flags to pass to the Binding

    transform_from

    ValueTransformer to use for forward transformation

    transform_to

    ValueTransformer to use for backwards transformation

    Return Value

    binding reference or nil in case of an error

  • get(property:) Extension method

    Get the value of a Bin property

    Declaration

    Swift

    @inlinable
    func get(property: BinPropertyName) -> GLibObject.Value

    Parameters

    property

    the property to get the value for

    Return Value

    the value of the named property

  • set(property:value:) Extension method

    Set the value of a Bin property. Note that this will only have an effect on properties that are writable and not construct-only!

    Declaration

    Swift

    @inlinable
    func set(property: BinPropertyName, value v: GLibObject.Value)

    Parameters

    property

    the property to get the value for

    Return Value

    the value of the named property

Bin Class: BinProtocol extension (methods and fields)

  • getChild() Extension method

    Gets the child of the GtkBin, or nil if the bin contains no child widget. The returned widget does not have a reference added, so you do not need to unref it.

    Declaration

    Swift

    @inlinable
    func getChild() -> WidgetRef!
  • child Extension method

    Gets the child of the GtkBin, or nil if the bin contains no child widget. The returned widget does not have a reference added, so you do not need to unref it.

    Declaration

    Swift

    @inlinable
    var child: WidgetRef! { get }
  • container Extension method

    Undocumented

    Declaration

    Swift

    @inlinable
    var container: GtkContainer { get }
