Doing several FLTK windows + the irrlicht one
Posted: Sun Jan 02, 2011 3:13 pm
Just thought I'd share the code for this experiment.
Simply put, FLTK does what it does much better than the builtin GUI possibilities. One can fairly easily pop FLTK windows and have them affect Irrlicht properties, as demonstrated.

// I just prefer all my projects to be efficient.
