- add fl_draw_radio(...) to standardize radio button drawing - src/Fl_Light_Button.cxx: use fl_contrast() to determine color of radio button and check (light) button check marks, and use new fl_draw_radio() method - src/Fl_Menu.cxx: same as src/Fl_Light_Button.cxx and use fl_draw_check() instead of "manually" drawing the check mark (forgotten in an earlier update)
README - Fast Light Tool Kit (FLTK) Version 1.4.0
WHAT IS FLTK?
The Fast Light Tool Kit is a cross-platform C++ GUI toolkit for
UNIX®/Linux® (X11 or Wayland), Microsoft® Windows®, and macOS®.
FLTK provides modern GUI functionality without the bloat and
supports 3D graphics via OpenGL® and its built-in GLUT
emulation. It was originally developed by Mr. Bill Spitzak
and is currently maintained by a small group of developers
across the world with a central repository on GitHub.
