Of course. Custom widget names are not assigned by default. They have to
be specified with gtk_widget_set_name (), preferrably at construction
time of the widget. Just name your widgets and you will be able to refer
to them by name.

By "no extra precautions" I was referring to custom extra operations
beyond internal GTK functionality, like Glade's add ons. Names, however,
are a GTK-provided standard property of all widgets. Code created by
Glade always assigns widgets unique (but not comprehensible) names. It's
your responsibility to name widgets so that you can refer to them later.

Note that the names of your C source code variables and the names of
widgets are two completely independent items. C variable names are of
importance / existance only during compile and link time. Widgets (and
their names) only exist at runtime of your application.
