Drop

open class Drop : GLibObject.Object, DropProtocol

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

The GdkDrop object represents the target of an ongoing DND operation.

Possible drop sites get informed about the status of the ongoing drag operation with events of type GDK_DRAG_ENTER, GDK_DRAG_LEAVE, GDK_DRAG_MOTION and GDK_DROP_START. The GdkDrop object can be obtained from these [classGdk.Event] types using [methodGdk.DNDEvent.get_drop].

The actual data transfer is initiated from the target side via an async read, using one of the GdkDrop methods for this purpose: [methodGdk.Drop.read_async] or [methodGdk.Drop.read_value_async].

GTK provides a higher level abstraction based on top of these functions, and so they are not normally needed in GTK applications. See the “Drag and Drop” section of the GTK documentation for more information.

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

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

    Declaration

    Swift

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

    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 Drop instance.

    Declaration

    Swift

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

    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 Drop 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 Drop instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
