LayoutManagerClassProtocol

public protocol LayoutManagerClassProtocol

The GtkLayoutManagerClass structure contains only private data, and should only be accessed through the provided API, or when subclassing GtkLayoutManager.

The LayoutManagerClassProtocol protocol exposes the methods and properties of an underlying GtkLayoutManagerClass 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 LayoutManagerClass. Alternatively, use LayoutManagerClassRef as a lighweight, unowned reference if you already have an instance you just want to use.
