Hi,
if you are using Qt, another approach could be to use the native Qt
event filtering. Just install a global event filter and either record or
directly stream the event data (using for example QTcpSocket) to the
other machine. The "client" then creates QEvent instances and uses
QCoreApplication::postEvent(...).

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 )
{
int eventID = mitkPostedEventID;
if( mitkPostedEventID == 0 )
{
//search the event in the list of event descriptions,
if found, then take the number and produce a stateevent
EventDescriptionVecIter iter;
for (iter = m_EventDescriptions.begin();
iter!=m_EventDescriptions.end();iter++)
{
if (*iter == *event)
break;
}
if (iter == m_EventDescriptions.end())//not found
return false;
eventID = (*iter).GetId();
}
//***************************************** the edited
code ************************************
mitk::BaseRenderer * c_Sender = event->GetSender();
int c_Type = event->GetType();
int c_Button = event->GetButton();
int c_ButtonState = event->GetButtonState();
int c_Key = event->GetKey();
mitk::Point2D c_DisplayPosition = dynamic_cast<const
mitk::PositionEvent*>(event) ->GetDisplayPosition() ;
mitk::Point3D c_WorldPosition = dynamic_cast<const
mitk::PositionEvent*>(event) ->GetWorldPosition() ;
std::ofstream eventfile;
eventfile.open("eventua.txt");
eventfile << eventID;
eventfile.close();
//*****************************************************************************
//set the Menger_Var m_StateEvent and send to
StateMachine, which does everything further!
m_StateEvent.Set( eventID, event );
/*
Group and Object EventId:
then EventMapper has the power to decide which
operations hang together;
each event causes n (n e N) operations (e.g.
StateChanges, data-operations...).
Undo must recall all these coherent operations, so all
of the same objectId.
But Undo has also the power to recall more
operationsets, for example a set for building up a new object,
so that a newly build up object is deleted after a Undo
and not only the latest set point.
The StateMachines::ExecuteAction have the power to
descide weather a new GroupID has to be calculated
(by example after the editing of a new object)
A user interaction with the mouse is started by a
mousePressEvent, continues with a MouseMove and finishes
with a MouseReleaseEvent
*/
switch (event->GetType())
{
case mitk::Type_MouseButtonPress://Increase
mitk::OperationEvent::IncCurrObjectEventId();
break;
case mitk::Type_MouseMove://same
break;
case mitk::Type_MouseButtonRelease://same
break;
case mitk::Type_User://same
break;
case mitk::Type_KeyPress://Increase
mitk::OperationEvent::IncCurrObjectEventId();
break;
default://increase
mitk::OperationEvent::IncCurrObjectEventId();
}
#ifdef MBI_INTERNAL_CONFERENCE
//Conference - pass local events through
if ( mitkPostedEventID == 0 )
{
mitk::CoreObjectFactory::GetInstance()->MapEvent(event,eventID);
}
#endif //MBI_INTERNAL_CONFERENCE
mitk::OperationEvent::ExecuteIncrement();
return
mitk::GlobalInteraction::GetInstance()->HandleEvent(&m_StateEvent);
}
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,
