Documentation

Pure virtual base class for adapting platform specific events into generic keyboard and mouse events.

Used as GUI toolkit-independent input into GUIEventAdapters. Viewer writers should subclass this base class to implement the functionality to translate one of their GUI events, e.g. a Qt Event or an MFC Event, as appropriate.
