[gtkada] Quitting program on the [X] button

[Rick Duley]

I am trying to gain an understanding of the thinking behind GtkAda so this
might seem a simple question but I'd still appreciate  knowing the answer.

Of the three buttons at top right of a top-level window, only the [X] button
requires an event handler to operate.

I think this is because the [X] button is the only button of the three which
requires control of the 'Main' loop.
Is that right?
