[IGSTK-Developers] GUI

[David Gobbi]

Hi Kevin,

Right now the View classes are still tightly tied to FLTK,
but there has been definite motion away from absolute
dependence of IGSTK on FLTK.

The Qt licensing issue is a biggie... TrollTech is very
explicit about their commercial licensing conditions.
Anybody working on Qt code that will eventually become
commercial, must hold a Qt commercial license before
they begin working on the code, otherwise the code is
strictly under the GPL and cannot be converted
to the Qt commercial license at a later date.

We can't have GPL code in IGSTK.  We possibly could have
Qt commercial code, but only if any developer who touched
that code held a Qt commercial license.  That's a hard thing
to regulate, but it is potentially doable.

 - David
