RE: Getting segmentation faults when setting text

["Dugas, Alan" <alan dugas analog com>]

The code looks ok assuming that text_entry_box is set to point to the gtkentry
in question prior to the call to gtk_signal_connect().  You might want to change
(GtkWidget *)text_entry_box to GTK_WIDGET(text_entry_box) to take advantage of
GTK's runtime error checking to make sure that text_entry_box is indeed pointing
to a gtkwidget before casting it into one.  In short, the former will force a
recasting of text_entry_box, the latter will check to make sure it's ok to
recast the variable before recasting it and send you a warning message if
something is wrong.
