SurfaceClassProtocol
public protocol SurfaceClassProtocol
The SurfaceClassProtocol
protocol exposes the methods and properties of an underlying GdkSurfaceClass
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 SurfaceClass
.
Alternatively, use SurfaceClassRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
