Detailed Description

Base class for handling WorldCanvas motion events.



WCMotionEH : WorldCanvas motion event-handler.


This is a base class intended to be derived from in applications. The user must write a derived class and override the operator() function. The operator() function is called whenever the pointer moves across the world canvas.

This base class does have a concrete implementation, namely to report to stdout events it receives. To effect this behaviour, create an instance this class and register it as an event-handler on a WorldCanvas.


Provide the user with an object-oriented approach to event handling and include world-coordinate position information.
