[Pypentago-devel] New GUI/Connection interaction approach

[Florian M. <flo...@ai...>]

I have been thinking about a different approach on how the Interface and
the Connection might interact. At the moment, the GUI functions to be
called are hard-coded into the Connection code. While this is okay, it
might be hindering if we plan to use a different GUI tool-kit or
refactor the GUI code.

So what I have thought about is a hook system. This means that the
connection code offers hooks that can be set by the GUI code, which are
executed after particular functions have been called. This would
emphasize the separation of GUI and Connection.

I have also thought about doing major changes to the easy_twisted
library which should allow it to send other data than strings. I could
either use JSON, where there is a module for Python, or write the
serialisation myself, which would of course be some work. This would
have the advantage that we could send lists and tuples over the network
with nearly no limitations(JSON has the limitation that dictionary keys
have to be strings).

So what do you think?

Best regards,
Florian Mayer
