On Windows this is optional, but FLTK uses it. X DnD is somewhat better as they realized it is the same thing as cut & paste. On Windows it looks like DnD is a complete mess and no code is shared at all between it and the clipboard. > Third (again I know for sure only from Windows) the OS can convert > some compatible formats (e.g. UTF-8 text and "ANSI" text, as it is > called in Windows, or Wide Character format, and also some different > graphics formats like bitmaps and JPEG). I don't think this works on Windows. FLTK converts the UTF8 to UTF16 and back again when going to the clipboard. I'm not sure what happens with UTF8 but I believe it fails to work in far too many applications. > The question is: in which cases could FLTK improve it to provide > multiple clipboard formats? I can only think of Fl_Help_View (html > and oridinary text). Anything else? I think the clipboard should remain text and contain a URL for any non-text data. _______________________________________________ fltk-dev mailing list fltk-dev@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-dev
