// Style demo for the Fast Light Tool Kit (FLTK).
//
// Demo of a control panel for Fltk "style" changes.
//
// You can use this as-is, or modify it to your needs.
//
// To save & restore a style you should write the data to a file of
// your own design.  Most likely your program has it's own configuration
// that you want to save as well, and it is user friendly to put all
// this into the same file.
