Re: Can TPad::AddExec call a method in PyROOT?

the tutorial makes use of finding the callable from the global space, and then calling it. Python methods can be bound, and then passed around as objects.

Something like:

     import __main__
     __main__.doSomething = self.doSomething
     self.can.AddExec( 'dynamic', 'TPython::Exec( "doSomething()" )' )

Not particularly pretty, but should work.
