Be GTK+ Extras
This package contains a field entry widget, a basic date and ip widgets and a calendar date widget that has an integrated GtkCalendar in a popup to facilitate date entry.
The Field Entry widget is a conversion to C from C++ of the same widget from libview (VMWare).
The Calendar Date Entry widget is an adaptation of the GtkDateEntry widget from Andrea Zagli <azagli@libero.it>.
The first uses a liberal license and the second uses the LGPL so I settled on the LGPL for this work.
