Called for list boxes that are bound to a GListModel with
ListBox.bindModel for each item that gets added to the model.
Versions of GTK+ prior to 3.18 called Widget.showAll on the rows
created by the GtkListBoxCreateWidgetFunc, but this forced all widgets
inside the row to be shown, and is no longer the case. Applications should
be updated to show the desired row widgets.
