I assume you use the source code generation feature of glade. Then, there
is also a file generated called support.[ch]. It defines only one public
function: lookup_widget (root_widget, widget_name). The root_wiget is a
pointer to the widget created by the create_* functions in interface.h,
the widget_name is the name you gave the widget within glade. Of course
you can only find a widget which is contained somewhere in the
root_widget.

If you have the reference to your desired widget (e.g. the textentry
widget) you can use the functions described in GTK/GNOME API docs at
developer.gnome.org to change the settings.

If you are completely new to GTK/GNOME I also suggest you to read the
greate "Gtk and GNOME Application Development" Book, which is also
available online under http://developer.gnome.org/doc/GGAD/
