Dear David,<br>
<br>
class MouseInteractorStyle<br>
------<br>
vtkSmartPointer<vtkUnstructuredGrid> Data;<br>
//vtkSmartPointer<vtkPolyData> Data;<br>
<br>
main<br>
vtkSmartPointer<vtkUnstructuredGrid> ug =<br>
vtkSmartPointer<vtkUnstructuredGrid>::New();<br>

style1->Data = ug;<br>
<br>
is all right. I can do it.<br>
If next cell is selected, previous cell highlight disappeared.<br>
I want to left it highlighted and also pick next time, want<br>
to erase it.<br>
Is it possible？<br>
<br>
Best regards,<br>
