Hello forum,

i believe this issue is already discussed here. But i could not figure out any reason of the following error related to vtable:


Qt Code: 
  1. ../../Build/H3DSceneEditor/Debug/H3DSceneHierarchy.o: In function `~H3DSceneHierarchy':
  2. /home/sajjad/Documents/H3DFunctionalSoFar/H3D/src/H3DSceneEditor/H3DSceneHierarchy.cpp:19: undefined reference to `vtable for H3DSceneHierarchy'

Qt Code: 
  1. class H3DSceneHierarchy : public  QObject
  2. {
  3.     Q_OBJECT
  4. public:
  5.  
  6.     H3DSceneHierarchy(QObject *parent = 0);
  7.  
  8.     ~H3DSceneHierarchy();
  9.  
  10. }

[CODE]


And in the source file


Qt Code: 
  1. H3DSceneHierarchy::H3DSceneHierarchy(QObject *parent)
  2.     : QObject(parent)
  3. {
  4.  
  5. }
  6.  
  7.  
  8. H3DSceneHierarchy::~H3DSceneHierarchy()
  9. {
  10.  
  11. }
To copy to clipboard, switch view to plain text mode 



Is there anything wrong in the above code ?
