DragSurfaceProtocol

public protocol DragSurfaceProtocol : SurfaceProtocol

The DragSurfaceProtocol protocol exposes the methods and properties of an underlying GdkDragSurface 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 DragSurface. Alternatively, use DragSurfaceRef as a lighweight, unowned reference if you already have an instance you just want to use.

A GdkDragSurface is an interface for surfaces used during DND.

DragSurface Interface

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

    Declaration

    Swift

    @discardableResult
@inlinable
func bind<Q, T>(property source_property: DragSurfacePropertyName, 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

    Declaration

    Swift

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

    Parameters

    property

    the property to get the value for

    Return Value

  • set(property:value:) Extension method

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

    Declaration

    Swift

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

    Parameters

    property

    the property to get the value for

    Return Value
