I'm not interested in making the fl_message work with drag-n-drop events or an application specific clipboard.  When I use a fl_message to display an error message to my users, I'd like for them to be able to copy/paste that message into an email for error reporting (and other use cases).

My wish is that this would be a simple behavior flag to turn on/off.  I suspect it will involve inheriting a custom fl_message_copyable and implementing an event handler with some magic sauce...  I have no experience with the system clipboard through FLTK, so I'm not sure where to start here.

Best,

Rob
