question: howto transfer objects between server and client?
Hello community,
maybe one of you can help me out with a question regarding the
transfer of objects betwen client an server:
I have three files:
### ClassA.py ###
class ClassA:
def setA(self, newA):
self.a = newA
def getA(self):
return self.a
### client.py ###
import xmlrpclib
from ClassA import *
a = ClassA()
a.setA(4711)
server = xmlrpclib.ServerProxy("http://localhost:";)
print server.getA(a)# <= here I would like to hand over an
object
### server.py ###
import SimpleXMLRPCServer
from ClassA import *
class Handler:
def getA(self, aClass):
return aClass.getA() # <- XMLRPC only transports simple types
and
dictionaries, but no objects
handler_object = Handler()
server = SimpleXMLRPCServer.SimpleXMLRPCServer(("localhost", ))
server.register_instance(handler_object)
print "Listening on port "
server.serve_forever()
The problem is, that though I hand a ClassA object to the XMLRPC
server, the server only receives a dictionary (only transfering simple
objects is a XMLRPC feature: http://docs.python.org/lib/module-xmlrpclib.html)
Since XMLRPC has limited features: Is there any other server/client
technique to transfer objects (not strings, or dictionaries, but self
defined object types) ?
Regards
Bernd

I love this python language ! Python is a really, really nice language and I often find that the solution is easier as I thought in the first place ... Thanks anyway !!

Question: wxpython and 3d engine example with model load ?
Hello, did anyone succeed in combining wxpython and a 3d engine (pyogre, crystalblend, panda3d, soya etc.) ? I would like to create an application, which uses wxpython tree, menu and grid elements and embedds a 3d view of some of the listed objects in an own detail window, so showing the object as a 3d model. I know there is PyOpenGL as well, but I need to load complete models (meshes done with cinema4d or blender) into the 3d view. So it would be very nice, if someone could post me a link to an example, where someone has successfully glued wxpython UI and a 3d engine view loading meshes into the 3d view.

wxstyledtextctrl and xml markup
Hello community, I want to create an editor for a self defined xml markup language. I want to use wxpython with wxstyledtextctrl and I have looked around at yellowbrain site, but there are no examples. I also watched the styledtextctrl examples with wxpython 2.8.4. What I am looking for is an example of how to do the autocompletion part for the styledtextctrl based on my self defined XML language. example: [...] Since I don't know styledtextctrl, I fear that I am about to write a complex handler for the autocompletion part, whereas there could be some easy to use features built into styledtextctrl. My problem is that I don't want to externalize the grammar of the XML instead of coding it inside the autocompletion handler. Are there any examples for wxstyledtextctrl, xml and autocompletion ?
