[PyKDE] Building PyQt as 1 shared library

[Peter Kropf]

To start, merging qttable into qt was fairly easy. I modified qtmod.sip,
adding %Include qtable.sip. Then rebuilding PyQt resulted in the qtable code
being included and accessable from python. Instead of:

    from qttable import QTable 

the python code now reads:

    from qt import QTable

As to why I want to do this, it has to do with deployment issues on Solaris.
(See my posting from yesterday titled "qttable and installer confusion on
windows and solaris" for details.) We're using Gordon McMillan's Installer
(which is a great tool) to create executables for distribution. All is well
when running in the development environment (Windows and Solaris) and in the
Windows distribution. But on Solaris we have runtime issues. I've been able
to trace the problem back to the fact that qt and qtable are two seperate
shared libraries. Why that matters, I don't know yet and it's very
frustrating. However by building qtable into the qt shared library, I'm able
to create a distribution package on Solaris that works.
