FrameClockSignalName

This signal ends processing of the frame.

Applications should generally not handle this signal.

Begins processing of the frame.

Applications should generally not handle this signal.

Used to flush pending motion events that are being batched up and compressed together.

Applications should not handle this signal.

Emitted as the second step of toolkit and application processing of the frame.

Any work to update sizes and positions of application elements should be performed. GTK normally handles this internally.

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.

Emitted as the third step of toolkit and application processing of the frame.

The frame is repainted. GDK normally handles this internally and emits [signalGdk.Surface::render] signals which are turned into [signalGtk.Widget::snapshot] signals by GTK.

Emitted after processing of the frame is finished.

This signal is handled internally by GTK to resume normal event processing. Applications should not handle this signal.

Emitted as the first step of toolkit and application processing of the frame.

Animations should be updated using [methodGdk.FrameClock.get_frame_time]. Applications can connect directly to this signal, or use [methodGtk.Widget.add_tick_callback] as a more convenient interface.
