Hi vtk users,<BR><BR><BR>I need some help with the vtkSphereWidget. I managed to use it but now I need to detect when the Left Button is released (or pressed whatever)<BR>SO i did something like that: <BR><BR><BR> sphereCallback = vtkSphereCallback::New();<BR><BR> sphereCallback->m_myClass= this;<BR><BR> m_lineWidget->GetSphereSource ()->AddObserver(vtkCommand::LeftButtonReleaseEvent,sphereCallback);<BR><BR><BR><BR>where vtkSPhereCallBack is<BR><BR><BR>class vtkSphereCallback : public vtkCommand<BR>{<BR> public:<BR> static vtkSphereCallback *New()<BR> {<BR> return new vtkSphereCallback;<BR> }<BR> <BR> virtual void Execute(vtkObject *caller, unsigned long, void*)<BR> { <BR> }<BR><BR> <BR> }<BR> vtkSphereCallback():m_myClass(0){}<BR> MyClass * m_myClass;<BR> <BR>};<BR><BR><BR><BR><BR><BR>But It doesn't work... the callback is not called when I release the the left button on the sphere... BUT if if put vtkCommand::InteractionEvent<BR>instead of vtkCommand::LeftButtonReleaseEvent in this case it works .. ! the callback is called... but now it will be called for everything.. but still not for the mouse click unclick...<BR>Even if I put " if (vtkCommand::LeftButtonReleaseEvent) {} " in the Execute function...<BR><BR><BR><BR><BR>Does someone has any Idea why ?,<BR><BR><BR>Regards,<BR>Adeline<BR><BR><BR>
