SignalRun Lastdevice-SignalRun Lastdevice-The ::device-changed signal is emitted whenever a device has changed in the hierarchy, either slave devices being disconnected from their master device or connected to another one, or master devices being added or removed a slave device.
If a slave device is detached from all master devices
(gdk_device_get_associated_device() returns null), its
Gdk.DeviceType will change to Gdk.DeviceType.FLOATING,
if it's attached, it will change to Gdk.DeviceType.SLAVE.
SignalRun Lastdevice-The ::device-removed signal is emitted either when a master pointer is removed, or when a slave (Hardware) input device is unplugged.
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.
The ::device-added signal is emitted either when a new master pointer is created, or when a slave (Hardware) input device is plugged in.
