[Sugar-devel] Launching a native python activity window

[TONY ANDERSON]

Hi, 

I have been using localhost and then have a cgi script in python use 
sugar-launch to launch the activity. 

The python script goes something like:

from subprocess import call

call('sugar-launch Memorize',shell=True)y

Ah, the develop activity. It actually has a nice simple hack


        from jarabe.model import bundleregistry
        from sugar3.activity import activityfactory

        registry = bundleregistry.get_registry()
        bundle = registry.get_bundle(self.bundle.get_bundle_id())
        activityfactory.create(bundle)


But that is launching an activity from a python activity. Maybe you need to
make some sort of shim for the web activity.
