GestureLongPressProtocol
public protocol GestureLongPressProtocol : GestureSingleProtocol
GtkGestureLongPress is a GtkGesture for long presses.
This gesture is also known as “Press and Hold”.
When the timeout is exceeded, the gesture is triggering the
[signalGtk.GestureLongPress::pressed] signal.
If the touchpoint is lifted before the timeout passes, or if
it drifts too far of the initial press point, the
[signalGtk.GestureLongPress::cancelled] signal will be emitted.
How long the timeout is before the pressed signal gets emitted is
determined by the [propertyGtk.Settings:gtk-long-press-time] setting.
It can be modified by the [propertyGtk.GestureLongPress:delay-factor]
property.
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.

onNotifyDelayFactor(flags:Extension methodhandler: ) 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 tog_object_set_property()results innotifybeing emitted, even if the new value is the same as the old. If they did passG_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly callg_object_notify()org_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.
