CustomLayoutProtocol

public protocol CustomLayoutProtocol : LayoutManagerProtocol

GtkCustomLayout uses closures for size negotiation.

A GtkCustomLayoutuses closures matching to the old GtkWidget virtual functions for size negotiation, as a convenience API to ease the porting towards the corresponding `GtkLayoutManager virtual functions.

The CustomLayoutProtocol protocol exposes the methods and properties of an underlying GtkCustomLayout 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 CustomLayout. Alternatively, use CustomLayoutRef as a lighweight, unowned reference if you already have an instance you just want to use.
