EventScrollRef

public struct EventScrollRef : EventScrollProtocol

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

    Declaration

    Swift

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

    Declaration

    Swift

    Declaration

    Swift
