void g_list_model_items_changed ( GListModel* list, guint position, guint removed, guint added )
GListModel::items-changed signal on
This function should only be called by classes implementing
GListModel. It has to be called after the internal representation
list has been updated, because handlers connected to this signal
might query the new state of the list.
Implementations must only make changes to the model (as visible to
its consumer) in places that will not cause problems for that
consumer. For models that are driven directly by a write API (such
GListStore), changes can be reported in response to uses of that
API. For models that represent remote data, changes should only be
made from a fresh mainloop dispatch. It is particularly not
permitted to make changes in response to a call to the
Stated another way: in general, it is assumed that code making a series of accesses to the model via the API, without returning to the mainloop, and without calling other code, will continue to view the same contents of the model.
