EventScroll

open class EventScroll : EventScrollProtocol

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

Generated from button presses for the buttons 4 to 7. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.

Some GDK backends can also generate “smooth” scroll events, which can be recognized by the GDK_SCROLL_SMOOTH scroll direction. For these, the scroll deltas can be obtained with gdk_event_get_scroll_deltas().

  • ptr 
    Untyped pointer to the underlying `GdkEventScroll` 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 EventScroll instance.

    Declaration

    Swift

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

    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 EventScroll instance.

    Declaration

    Swift

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

    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 EventScroll 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 EventScroll 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 EventScroll instance.

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Reference intialiser for a related type that implements EventScrollProtocol GdkEventScroll does not allow reference counting.

    Declaration

    Swift

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

    Parameters

    other

    an instance of a related type that implements EventScrollProtocol

    Parameters

    cPointer

    pointer to the underlying object
