SignalRun Firstbegin-SignalRun Firstend-This signal is emitted as soon as the gesture has stopped.
The user is expected to animate the deceleration from the current progress
value to to with an animation using velocity as the initial velocity,
provided in pixels per second. SpringAnimation is usually a good
fit for this.
SignalRun FirstprepareThis signal is emitted when a possible swipe is detected.
The direction value can be used to restrict the swipe to a certain
direction.
SignalRun Firstupdate-This signal is emitted every time the progress value changes.
SignalDetailedActionRun FirstnotifyThe 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
GObject.ParamFlags.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 GObject.ParamFlags.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:
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][class@GObject.ParamSpec#parameter-names] as detail strings for the notify signal.
This signal is emitted right before a swipe will be started, after the drag threshold has been passed.
