For me, I've always wanted all the widgets in a window dialog displayed,
that's why I put them in there.  This latest experience is the first time
I've ever wanted to sometimes have one hidden.  I'd figured that since I
could set sensitivity, a GEntry's initial text, and so on, I'd be able to
preset the visibility of a widget as well.  Perhaps a better name than
"Set_Visible" for such a function is "Set_Visibility"?

Now perhaps I'm mistaken here, but I think I recall reading something that
if you use a sequence of Show calls that you might end up "watching the GUI
being constructed"; versus a Show_All where the whole thing pops onto the
display at once.

My GUIs tend to have a lot of post-Gtk_New tweaking done to them--such as
setting widget sensitivities and GEntry contents--so I like being able to
construct the whole thing with a single Glade-generated Gtk_New call,
configure it as needed, and then throw it up on the screen with a Show_All.
