[Paraview] Custom Qt Filter Panel

[Robert Maynard]

Thanks for the help. I have found the problem being how it qt / paraview
handles relative paths. Instead of the file using the path for plugin .so
being the root, it actually uses the runtime directory as the root
directory. Which means if I launch paraview from  my home directory, or from
the bin exactly I get different expectations on where my UI file should
reside.

The solution to this seems to be that the paraview developers have used a
:/pqWidgets link to handle this problem, but I would like to know if there
is a away for me to set the relative path starting directory to where the
.so or the source code resides.

(The way i found this out, was i dumped absolute file paths using QFileInfo
inside pqLoadedFormObjectPanel )
