+// 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.

+////////////////////////////////////////////////////////////////
+// This is the part you want to copy to another program.  The
+// program should call "show_style_panel()" in response to a button
+// that the user presses.
