Public method to initialize the value of the Fl_Scheme_Choice widget.
Normally you don't need to call this unless you change the current scheme by calling Fl::scheme(const char *).
The Fl_Scheme_Choice widget does this automatically when the widget is shown (when receiving the FL_SHOW event) which should always be after Fl_Window::show(argc, argv) which may set the current scheme by interpreting the commandline.

Internal Fl_Scheme_Choice callback function (protected).
You don't need to set a callback for this widget. The default callback changes the scheme (Fl::scheme()) and redraws all open windows.
You may override the callback if changing the scheme shall redraw other windows or don't redraw the window at all.
