Combining Tcl/Tk with C++

[Kenneth Wang]

Hi Jordi,

I asked a similar question a little while back, and with James
Miller's help, I found that it's quite simple to take vtk objects from
Tcl and import them into your C/C++ code.  Take a look at
common/vtkTclUtil.cxx.  In particular, look at
vtkTclGetPointerFromObject.  Using this function, and given an
object's Tcl name and vtk type, you can just look up the pointer to
that object.

Going the other way, i.e. exporting a vtk object from your C/C++ code
back to the vtk table of Tcl objects, is something which appears a
bit more complicated, and I haven't figured this out yet.  Does anyone
out there have any tips for doing this?

-Ken
