When I run the program, the first item is selected initially on
Unix/Gtk. Clicking the item doesn't change the selection, and so the
callback isn't triggered.
If I add
(send lb select 0 #f)
before showing the frame, then the first item is not selected when the
frame appears, and clicking the first item triggers the callback.
I see that no item is initially selected on Mac OS X and Windows, so it
makes sense to change Unix/Gtk to be more consistent. In fact, the
current Gtk binding for `list-box%` goes out of its way to make
something selected, so I can easily disable it. I've pushed the change.
Does that sound right?
