Hi,
the problem here is that you accidentally mixed an old Interaction Event with a
new Interaction.
What you are looking for is the InteractionPositionEvent (see [1] for an
inheritance diagram).
This should work:
InteractionPositionEvent* pos = dynamic_cast<InteractionPositionEvent*>
(interactionEvent);
if (pos != NULL)
{
m_DisplayPosition = pos->GetPointerPositionOnScreen();
m_WorldPosition = pos->GetPositionInWorld();
}
Are you working in the 2D or 3D render window ?

Subject: [mitk-users] Mouse Interaction
hello Mitk users,
I am defining my own interaction according to the last discussion on "add a new
state machine". I want to realize a mouse hover that detect if a DataNode is
present in the RenderingWindow at the same position as my mouse pointer. The
interactor detects the movement of the mouse, but when I intend to pick up the
coordinates of the mouse pointer in the RenderingWindow through the
DisplayPositionEvent, it gives me NULL results.
Here is my code where I can not go over the while loop for any position of the
mouse.
bool mitk::MyPlaneDataInteractor::ColorOnPlane(StateMachineAction*
stateMachineAction, InteractionEvent* interactionEvent)
{
const DisplayPositionEvent *dpe = dynamic_cast<const
DisplayPositionEvent*>(interactionEvent);
while(dpe == NULL)
{
break;
}
... rest of the code
}
Someone has any idea of how can I pick up my mouse position with my interactor?
Thanks.
