PointProtocol

public protocol PointProtocol

The PointProtocol protocol exposes the methods and properties of an underlying GdkPoint 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 Point. Alternatively, use PointRef as a lighweight, unowned reference if you already have an instance you just want to use.

Defines the x and y coordinates of a point.
