[vbox-dev] How to create an object implementing VirtualBoxCallback from python?

[Nikolay Igotti]

    Hi Francisco,

 Few days ago generic mechanism was implemented  for callback handlers 
creation, see function createCallback() in VirtualBoxManager.
One can use it like this:

class MyCallback
    def onMachineStateChange (self, ...):
       ....
   # implement all  methods of IVirtualBoxCallback here

 cb = mgr.createCallback('IVirtualBoxCallback', MyCallback)
 mgr.vbox.registerCallback(cb)

This approach shall work for both XPCOM and MS COM targets.

  Thanks,
    Nikolay
