libexo is an extension library for Xfce. While
Xfce ships with quite a few libraries that are
primarly targeted at desktop development, libexo
is targeted at application development, with a
focus on applications for Xfce. It contains
several additional widgets (e.g. an icon bar and
widgets that automatically ellipsize text),
provides a framework for editable toolbars,
light-weight session management support, functions
to automatically synchronize object properties,
and several miscelleanous utility and helper
functions useful for application developers.
