[vtkusers] How to make vtkLogoWidget undraggable

[Cory Quammen]

Skimming the code in vtkLogoWidget's parent class vtkBorderRepresentation,
it looks like there is no way to disable dragging at the moment.

One could change the code in
vtkBorderRepresentation::WidgetInteraction(double eventPos[2]) in the
switch statement case for vtkBorderRepresentation::Inside to also check if
dragable is set to off, e.g.

    case vtkBorderRepresentation::Inside:

      if ( this->Moving* && this->Dragable*)
        {
        par1[0] = par1[0] + delX;
        par1[1] = par1[1] + delY;
        par2[0] = par2[0] + delX;

        par2[1] = par2[1] + delY;

        }
      break;

Note the change in bold. Would you want to give this a try and see if that
works?

Thanks,
Cory
