SelectionModelInterfaceProtocol

public protocol SelectionModelInterfaceProtocol

The list of virtual functions for the GtkSelectionModel interface. No function must be implemented, but unless GtkSelectionModelis_selected() is implemented, it will not be possible to select items in the set.

The model does not need to implement any functions to support either selecting or unselecting items. Of course, if the model does not do that, it means that users cannot select or unselect items in a list widget using the model.

All selection functions fall back to GtkSelectionModelset_selection() so it is sufficient to implement just that function for full selection support.

The SelectionModelInterfaceProtocol protocol exposes the methods and properties of an underlying GtkSelectionModelInterface instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see SelectionModelInterface. Alternatively, use SelectionModelInterfaceRef as a lighweight, unowned reference if you already have an instance you just want to use.
