Hi Joel,
probably the easiest way to interface with IB (don't know about MyTrack)
would be via IB's C++ API directly from Python using wrapper classes as
indicated.
This is much preferable to using Jython. Python (and its VM) being written
in C, naturally the connection to the C and C++ world is the most
straightforward. You will then continue to have access to all Python
libraries including wxPython and others. There are quite a few Python libs
that have not been ported to Java because Java already has the respective
capabilities, such as a good graphics library.
Therefore, Jython is good if and when you want to mainly live in Java land.
If you plan on using Swing or Eclipse in your coding, and Python only as a
secondary language, then the use of Jython would be indicated. The great
thing about Jython is that you can use all of the *Java* libs from Python,
not vice versa.
Another way to link to Java from Python would be via Java's JNI plus Python
wrappers, but as IB offers a C++ API, why bother?
Best regards,
Michael Suesserott
