[vtkusers] Crosshair on 2D medical image display

[Xiaofeng Z]

I'm working on a software uses multiplanar rendering.  It seems to be a standard feature in MPR to have the cross-hair for moving the focal point, e.g. the blue, green, and red lines in the the following screen shot.

I'm wondering if a widget of such already exist in VTK.  If not, would anyone so kind to point me a direction how to implement one.
 
Thanks!

Hello vtkUsers,
 
I'm wondering what's the best way the make the crosshair overlay on medical image displayed in 2D.  Is a customized vtkHandleWidget the way to go?

Thanks!
