Signals inherited from GActionGroup (4)
GActionGroup::action-added
Signals that a new action was just added to the group. This signal is emitted after the action has been added and is now visible.
GActionGroup::action-enabled-changed
Signals that the enabled status of the named action has changed.
GActionGroup::action-removed
Signals that an action is just about to be removed from the group. This signal is emitted before the action is removed, so the action is still visible and can be queried from the signal handler.

GListModel::items-changed
This signal is emitted whenever items were added to or removed
from list. At position, removed items were removed and added
items were added in their place.
