One thing that can be useful in some cases is to set the size request of
a widget to be a single pixel in one direction:

gtk_widget_set_size_request (entry, 1, -1);

(-1 means use the widget's value). This avoids arbitrary numbers.
gtk_entry_set_width_chars (entry, 0) is probably an even better match
for your case, since it will take the border of the entry into acount.
