[IGSTK-Users] A question about igstkEventTransductionMarco

[Matt Turek]

Vincent,

Unfortunately, the ViewNew class and many others, including the tracker 
and spatial object classes, are undergoing a major refactoring right 
now. So, I'm not surprised that they are not working in IGSTKSandbox. It 
will probably be another week or more before they are in usable shape.

Luis is looking at the igstkEventTransductionMacro bug.

Thanks for the continued interest in IGSTK.

Matt
