__author__ = 'karim'

from gi.repository import Gtk


def tata(event, data):
    print('tata')

win = Gtk.Window()
win.set_title('test')
win.connect('delete-event', Gtk.main_quit)
win.connect('button-press-event', tata)
win.show_all()

Gtk.main()

but when i tried to bind enter-notify-event that has worked, when my mouse enter the win region, the console show me the message tata :

__author__ = 'karim'

from gi.repository import Gtk


def tata(event, data):
    print('tata')

win = Gtk.Window()
win.set_title('test')
win.connect('delete-event', Gtk.main_quit)

Documentation on button-press-event says:

To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_BUTTON_PRESS_MASK mask.

So import Gdk as well and then do 

win.set_events (Gdk.EventMask.BUTTON_PRESS_MASK)

That should make your example work.

In the text you also mention a frame. If you plan on doing the same thing with a GtkFrame note that only widgets with their own window can receive events, and containers like Frame typically do not have a window. You may have to put the frame inside a EventBox that can receive the events.
