[vtkusers] VTK and Qt -> making buttons work

[Jennifer Lyon]

Hello All!

I am using VTK and Qt together, and becoming frustrated trying to make a
button in the Qt window interact with a VTK widget.  For example, trying to
create a button to rotate/change to wireframe/render other actor/etc.  in
the VTK window.

I think that my signals and slots are set up correctly, but possibly there
is some key component to having a button interact that i am unaware of.  My
buttons are useless.  :(

Hopefully some of you have come across a similar situation!

Thanks in advance!
