go catch the activate signal on every single GtkEntry widget
(rather than having widgets whose activate signal is *not*
caught not catch the Return keystroke, so that it passes on,
ultimately, to the window, which can activate the default
widget, i.e. the "OK" button); we have to catch the "key_press_event"
signal and have the handler check for ESC, so that we can have ESC
activate the "Cancel" button; in order to support Alt+<key> mnemonics
for buttons and the like, we may have to construct an accelerator
group by hand and set up the accelerators by hand (if that even
works - I've not tried it yet); we have to do a "gtk_widget_grab_focus()"
to keep some container widget from getting the initial focus, so that
you don't have to tab into the first widget in order to start typing
in it; and it now appears that you simply *can't* make a combo box
get the initial focus, at least not in the obvious fashion. Sigh.... */
