[vtkusers] vtk, tcl/tk, and C++

[Edward Block]

We have written a C++ program to try to display and process some
pseudo-realtime
data. The C++ code uses vtk to create a window in which the collected images
are
displayed and a tk "window" with all the GUI stuff in it.

We need to use C because of the enormous amount of math manipulations done
on the
data (ie. fftw).

I would like to know how to tie the multiple windows together so they feel
like one
application. Any ideas on how the 3 languages (Vtk, Tcl/Tk, C) can better
communicate?
DO we need to go to using sockets or is there a way to pass such things as
pointers to windows and frames to and fro?
