Hi Jim,
thanks for links, it looks interesting, I'll try it, but I don't know if
this is right way. I can see that pyjamas code is little bit unstable,
Pyjamas Desktop needs some patches and non-standard packages, so it will
be a problem for deployment.
But I was looking at the Zope view capabilities again, and may by best
solution will be write a XML-RPC view and remote client program based on
XML-RPC (wxPython GUI) which will be able to view and/or modify content
in Zope instance.
Any advices? Can I control whole Zope instance content using remote
XML-RPC client or there is problem with some type of content? I know
that XML-RPC has just few supported data types and I am not sure if this
is sufficient for all content types in Zope. At this time I think that I
will need just boolean, string, integer, float and binary data types,
but I am not completely sure, I am just at the beginning of analyze.
