[vtkusers] vtkLineWidget2 - customize/restrain interaction?

[Matthias Riechmann]

Hi,

that's something I was interested, too. But while trying to implement an 
alternative version of vtkLineWidget I discovered some - I don't want to 
call it hack, but it's a weired construct - problems in the 
"architecture" of the widgets "framework": vtkLineWidget makes use of 
vtkPointWidget and calls it's ProcessEvents method, which is protected 
but a friend of vtkLineWidget meaning this method can only be called 
from vtkPointWidget or the ORIGINAL vtkLineWidget. So the problem is: 
You can't just copy and modify the code of vtkLineWidget without making 
changes within the VTK. So a complete redesign of the line widget would 
be necessary and possibly this still would not work out. At this point I 
decided the original line widget isn't that bad anyway...

But maybe one of the vtk developers has a better idea. Besides I heard 
about effords of redisigning the 3d widget. But maybe those are only 
rumors...
