[pygtk] vtk problem with libpng
[ I have been having trouble with my pygtk mailing list subscription
and am resending this since it bounced the first time. Apologies for
any duplicates]
I am developing an application which uses vtk with pygtk-2.0.0. When
I import vtk (whether or not I use it), my stock gtk icons no longer
work under redhat 9, and I get errors like the following
(toolbar_test.py:23182): Gtk-WARNING **: Error loading icon: Failed to load image
'/usr/share/icons/Bluecurve/24x24/stock/gtk-new.png': Fatal error in PNG image file:
Incompatible libpng version in
application and library
With the same version of VTK and pygtk, I had no problems under redhat
linux 8 (I just upgraded the OS) so it looks like a incompatibility
between a new libpng and a png lib that ships with VTK. I am not sure
how to proceed in fixing it, so I'm looking for suggestions.
Below is a test script which replicates the problem. When you comment
out the import vtk line, the error messages go away and the icons
display fine.
It's not clear to me importing vtk would change the libpng that gtk is
linking with.
Any suggestions welcome,
John Hunter

If you look in Wrapping/Python/vtk/gtk/ you'll see a class
GtkVTKRenderWindow that contains a demo in the __main__ section at the
bottom. Currently, this works only with a patched version of pygtk
provided by John K Luebs that exposes xid. You'll have to rebuild
pygtk from cvs with this patch.
It appears that people are moving to gtkglext, however, so I recently
adapted the gtkgl render window that ships with vtk to work with
gtkglext. The same patch caveat applies.
Also, it currently only works under X windows because I am having
trouble getting pygtkglext working under win32 and hence can't test
the use of hwnd in place of xid for the gtkglext code. But I expect
to have this resolved soon. If you need this platform, let me know
and I can provide you with an installer.
Here is some demo code and the gtkglext render window class
