[vtk-developers] vtkSeedWidget proposed modifications

Hi Karthik,

and anyone else who might know how to fix this:

vtkSeedWidget.cxx
C:\Dashboards\My Tests\VTK\Widgets\vtkSeedWidget.cxx(75) : error C2065:
'advance' : undeclared identifier

Problem with Continuous build for  DASH3.kitware/Win32-vs60

is there a namespace for the STL advance method I am missing here?

Dean

Hi Dean,

Thanks for improving the behavior of the widget.

Is any API broken in the process, or is it restricted to an improvement in
behaviour ?

If so, please commit it.

Thanks
