EventTouch

open class EventTouch : EventTouchProtocol

The EventTouch type acts as an owner of an underlying GdkEventTouch instance. It provides the methods that can operate on this data type through EventTouchProtocol conformance. Use EventTouch as a strong reference or owner of a GdkEventTouch instance.

Used for touch events. type field will be one of GDK_TOUCH_BEGIN, GDK_TOUCH_UPDATE, GDK_TOUCH_END or GDK_TOUCH_CANCEL.

Touch events are grouped into sequences by means of the sequence field, which can also be obtained with gdk_event_get_event_sequence(). Each sequence begins with a GDK_TOUCH_BEGIN event, followed by any number of GDK_TOUCH_UPDATE events, and ends with a GDK_TOUCH_END (or GDK_TOUCH_CANCEL) event. With multitouch devices, there may be several active sequences at the same time.

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

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

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

  • Designated initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the EventTouch instance.

    Declaration

    Swift

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

    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 EventTouch instance.

    Declaration

    Swift

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

    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 EventTouch instance.

    Declaration

    Swift

    @inlinable
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 EventTouch instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • Optional 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 EventTouch instance.

    Declaration

    Swift

    @inlinable
public init!(_ op: UnsafePointer<GdkEventTouch>?)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the EventTouch instance.

    Declaration

    Swift

    @inlinable
public init!(_ op: UnsafeMutablePointer<GdkEventTouch>?)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from the underlying C data type. GdkEventTouch does not allow reference counting, so despite the name no actual retaining will occur. i.e., ownership is transferred to the EventTouch instance.

    Declaration

    Swift

    @inlinable
public init(retaining op: UnsafeMutablePointer<GdkEventTouch>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Reference intialiser for a related type that implements EventTouchProtocol GdkEventTouch does not allow reference counting.

    Declaration

    Swift

    @inlinable
public init<T>(_ other: T) where T : EventTouchProtocol

    Parameters

    other

    an instance of a related type that implements EventTouchProtocol

    Parameters

    cPointer
