[vtkusers] interactor with edge

[zhangming]

hi all,
  
    I've come across coloring edge cell.But if I use the code I can color the triangle cell correctly.

tempActor->GetMapper()->GetInput()->GetCellData()->GetScalars()->SetTuple1(CellID,red);
tempActor->GetMapper()->Modified();
renWin->Render();

When the tempActor's cell type is triangle,this code can work right.but when the tempActor cell type is edge,the color of edge doesn't change.

I am sure that the scalars is changed but the color doesn't change. why? the changing doesn't represent?

many thanks
