[Insight-users] SpatialObjects GetParent() problem

[Luis Ibanez]

Hi Xabier,

The second expression:

SegmentSpatialObject * auxSegment2 = dynamic_cast<
           SegmentSpatialObject *> (auxSegment->GetParent());


should be the right one to use.


Does the runtime that you get happens because

           auxSegment2 == 0  ?

If so, there may be something wrong in the declaration
of derivation of your SegmentationSpatialObject.

Could you please post to the list the header (.h) file
of your class ?


    Thanks


       Luis
