GestureDragRef

public struct GestureDragRef : GestureDragProtocol, GWeakCapturing

GtkGestureDrag is a GtkGesture implementation for drags.

The drag operation itself can be tracked throughout the [signalGtk.GestureDrag::drag-begin], [signalGtk.GestureDrag::drag-update] and [signalGtk.GestureDrag::drag-end] signals, and the relevant coordinates can be extracted through [methodGtk.GestureDrag.get_offset] and [methodGtk.GestureDrag.get_start_point].

The GestureDragRef type acts as a lightweight Swift reference to an underlying GtkGestureDrag instance. It exposes methods that can operate on this data type through GestureDragProtocol conformance. Use GestureDragRef only as an unowned reference to an existing GtkGestureDrag instance.

  • ptr
    Untyped pointer to the underlying `GtkGestureDrag` instance.
    

    For type-safe access, use the generated, typed pointer gesture_drag_ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

GestureDrag Class

  • Designated initialiser from the underlying C data type

    Declaration

    Swift

  • Designated initialiser from a constant pointer to the underlying C data type

    Declaration

    Swift

    init(_ p: UnsafePointer<GtkGestureDrag>)
  • Conditional initialiser from an optional pointer to the underlying C data type

    Declaration

    Swift

    @inlinable

  • Conditional initialiser from an optional, non-mutable gconstpointer

    Declaration

    Swift

  • Reference intialiser for a related type that implements GestureDragProtocol

    Declaration

    Swift

    @inlinable
    init<T>(_ other: T) where T : GestureDragProtocol
  • This factory is syntactic sugar for setting weak pointers wrapped in GWeak<T>

    Declaration

    Swift

    @inlinable
    static func unowned<T>(_ other: T) -> GestureDragRef where T : GestureDragProtocol
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to GestureDragProtocol.

    Declaration

    Swift

    @inlinable
    init<T>(cPointer: UnsafeMutablePointer<T>)
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to GestureDragProtocol.

    Declaration

    Swift

    @inlinable
    init<T>(constPointer: UnsafePointer<T>)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to GestureDragProtocol.

    Declaration

    Swift

    @inlinable
    init(mutating raw: UnsafeRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to GestureDragProtocol.

    Declaration

    Swift

    @inlinable
    init(raw: UnsafeMutableRawPointer)

    Declaration

    Swift

    @inlinable
    init(opaquePointer: OpaquePointer)
  • Returns a newly created GtkGesture that recognizes drags.

    Declaration

    Swift
