The FLTK use case seems to overlap heavily with wxWidgets. Are there reasons to choose one over the other?
replies(1):
FLTK draws the controls on its own - for the better (incredibly fast, consistent across platforms, flicker free since 1998, super easy to implement new widgets) and for the worse (bad support for complex text layout in Asian and bidi languages, no support for accessibility)
I would say it’s the wrong tool for a mass-market product or if you need non European language support.
It’s the perfect tool for internal projects that only require European/English languages.
In between those, depend on the details.
