[vtkusers] bug in vtkLogoRepresentation

[Paul Harris]

That didn't work, instead I moved the Selectable check further up, like so:

  // Set the cursor appropriately
-->  if ( self->Selectable && self->WidgetState == vtkBorderWidget::Start )
    {
    int stateBefore = self->WidgetRep->GetInteractionState();
    self->WidgetRep->ComputeInteractionState(X, Y);
    int stateAfter = self->WidgetRep->GetInteractionState();
    self->SetCursor(stateAfter);

--->    if ( stateAfter != vtkBorderRepresentation::Inside )

Now the mouse doesn't change cursor either, which is good.

I'm not sure if that is correct, theres this bit of code further down:

  if(!self->Resizable &&
    self->WidgetRep->GetInteractionState() !=
vtkBorderRepresentation::Inside)
    {
    return;
    }

I don't want it resizable either.  It doesn't appear to be...

cheers
Paul
