GestureLongPressProtocol

public protocol GestureLongPressProtocol : GestureSingleProtocol

GtkGestureLongPress is a GtkGesture implementation able to recognize long presses, triggering the GtkGestureLongPress::pressed after the timeout is exceeded.

If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, the GtkGestureLongPress::cancelled signal will be emitted.

The GestureLongPressProtocol protocol exposes the methods and properties of an underlying GtkGestureLongPress instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see GestureLongPress. Alternatively, use GestureLongPressRef as a lighweight, unowned reference if you already have an instance you just want to use.

    Untyped pointer to the underlying GtkGestureLongPress instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer! { get }
  • gesture_long_press_ptr Default implementation

    Typed pointer to the underlying GtkGestureLongPress instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GtkGestureLongPress instance.

  • onCancelled(flags:handler:) Extension method

  • onPressed(flags:handler:) Extension method

  • The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

    Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

    This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

    (C Language Example):

    g_signal_connect (text_view->buffer, "notify::paste-target-list",
                      G_CALLBACK (gtk_text_view_target_list_notify),
                      text_view)
    

    It is important to note that you must use canonical parameter names as detail strings for the notify signal.

    Note

    This represents the underlying notify::delay-factor signal

    Flags

    unownedSelf

    pspec
