[pygtk] TextView selection event

[Dmitry Shamov]

Hello I am writing an application with PyGTK and collided with a
problem: I want to toolbar buttons cut, copy to be enabled when you
receive the allocation.
To do this, TextView, I follow the event move-cursor. But if the
cursor is moved with the keyboard, everything works fine. But if you
move it with the mouse, this event is not triggered.
somebody had the same problem?
GTK 2.14.2
