Hello,
I'm pretty new to MITK and and for a project i'm involved i need to capture
the mouse events and key events perfomed in gui. For this purpose i modified
the mapEvent function of mitkEventMapper.cpp as following.
bool mitk::EventMapper::MapEvent(Event* event, int mitkPostedEventID )

when i add the lines the project builds without errors.
> mitk::Point2D c_DisplayPosition = dynamic_cast<const
> mitk::PositionEvent*>(event) ->GetDisplayPosition() ;
mitk::Point3D c_WorldPosition = dynamic_cast<const
> mitk::PositionEvent*>(event) ->GetWorldPosition() ;
i get a runtime error when running step5. (step5.exe crashes.)
what i need to do in my project is capture mouse events from one machine and
make them happen in a remote computer. (using a log of captured events)
I'm hoping to use mitkconferenceeventmapper.cpp to achieve this.
I would be very grateful if anyone could tell me wats wrong with the above
lines.
Any alternatives to get my task done would be very helpful.
Thanks in advance.
Best Regards,
