Actually I gather he's doing something different in the places I left
in....

Dialog boxes are generally optimised to be used in one of two ways:
1) as a modal dialog, where you add some buttons with associated
values, call the "run" method as Ed did, and get a return value
corresponding to the button.
2) as a non-modal dialog, where you use to "show" method as Harry did,
but you also override the dialog class's "on_response" method to handle
the button presses.

In both cases you need to do the hiding yourself, for example after
calling "run" or within the on_response method.
