[[PUI]] is the standard GUI engine used in FlightGear, it is part of [[PLIB]] and is using raw, fixed-pipeline, [[OpenGL]] code internally (no [[OpenSceneGraph]]). PUI provides a fairly basic, but robust, set of widgets. PUI is also used for rendering the [[Menubar]].

FlightGear uses a GUI widget set that is implemented on top of [[OpenGL]].  This has many advantages from a portability standpoint and from the standpoint of integrating with window systems.  [[PUI]] doesn't have every feature under the sun, but it was never meant to.  It's relatively small, lean, mean, and written on top of [[OpenGL]] which makes life *much* easier for us.


[[PUI]] already is a separate distinct library within Plib.  It depends on some central utility stuff, but that's about it.  So it is pretty stripped down and separate already.<ref>https://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg26011.html</ref>

We are to some extent hamstrung by the rather old GUI toolkit we use. However, replacing that is going to be non-trivial, and it would affect not just the core GUI but also all the dialog boxes that have been set up for particular aircraft.<ref>https://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg25985.html</ref>
