GEM++ - C++ LIBRARIES FOR GEM/AES/VDI
NAME
GEMkeysink - Consumes keypress events
DESCRIPTION
A GEMkeysink is an event handler that acts when a key is pressed.
Only one GEMkeysink may be attached to a GEMactivity at present,
though this may change in future.
This class is an abstract base class because Consume() is undefined.
CONSTRUCTORS
GEMkeysink(GEMactivity& in)
Create a GEMkeysink which will consume key events from the given
GEMactivity.
METHODS
virtual GEMfeedback Consume(const GEMevent&)=0
This method should act on the given GEMevent - usually by
accessing GEMevent::Key().
SEE ALSO
GEMevent, GEMactivity
