Thanks Gonzalo,
Thanks Gonzalo. I was intrigued by that fact and looked a bit at the issue.

Use clicked instead of button-pressed, because this is not triggered
by touch device.
Makes sense, clicked is more general than button-pressed. From the
docs, "is emitted when the button has been activated (pressed and
released)".

I tested the behavior in GTK+3 and GTK+2, and it does behave differently:
In Gtk+2 I do get as well the press&release events with touch. In Gtk+3
I do not, only the clicked signal. Looking at the docs [1] the
button-release-event is only submitted when it is enabled using the
mask. Tried that, but the behavior is the same.
I am fine to go with 'clicked' as Gonzalo suggested but would be nice to
know the details as well.
