[vtkusers] capture mouse position

[Diego Parada]

Hi;

I can't get the mouse positon, the code is:

//replace the vtkCommand
void OnLButtonUp(vtkObject *caller, unsigned long eid, void *clientdata, 
void *calldata)
{
int x,y;

vtkInteractorStyle * istyle = (vtkInteractorStyle *) caller;
vtkRenderWindowInteractor * iren = istyle->GetInteractor();
iren->GetMousePosition(&x,&y); 
}
// whit style interactor

vtkInteractorStyle * istyle = vtkInteractorStyle::New();
vtkCallbackCommand * LMouseUp = vtkCallbackCommand::New();
LMouseUp->SetCallback(OnLButtonUp);
istyle->AddObserver(vtkCommand::LeftButtonReleaseEvent,LMouseUp);
this->m_InteractorRender->SetInteractorStyle(istyle);

the code runs but not capture the mouse position

the application is made in VC++ 6.0 MFC


Thanks
