This is of course a design choice, and you can easily implement a small
layer on top of GtkAda to do just that.
The advantage with pointers is that you can add or remove callbacks during
the life of a widget, which is harder to do with primitive operations where
you need flags to know whether to react to the event or not. Also you can
have multiple callbacks on the same signal, which, again, is harder to do
with primitive operations.
