[STR New] Link: http://www.fltk.org/str.php?L2904 Version: 1.3-feature No, perhaps you misunderstand: it is not necessary to copy/paste anything from gtk. What we'd have to do would be something like this: (note that this is essentially what the Win32 and OSX cases do...) - We write a (probably C language) wrapper for launching GtkFileChooserDialog programmatically from within fltk, and passing in the various options that fltk knows and converting them to the GtkFileChooserDialog equivalents. (Turns out this might be quite straightforward, I had a brief look at the GTK+ docs last night and it seems do-able!) - At runtime, if someone wants a file-chooser, we use dlopen (or something...) to check for the presence of the required gtk/glib .so files and load them if available, then use our GtkFileChooserDialog wrapper. - if the gtk .so are not available, we use our stock fltk file-chooser instead, as we do at present. - Of course, on subsequent calls to the file-chooser we don't have to re-check for gtk, we already know the answer... As I say, this is very similar to what we do on other platforms, and only one file will contain any gtk+ code, so we are not importing large chunks of another toolkit or anything, just using their public API and calling the existing libs. Also, by loading the gtk libs via dlopen that ensures we do not need to link against those libs if we are not using them. Well, something like that, anyway. FWIW, I wrote a simple wrapper to test opening GtkFileChooserDialog in "Open File" and "Save As" mode, and it seemed to work and wasn't all that much code, so I think this can be made to function. Though creating the code to map all the fltk options onto GTK options is going to be non-trivial! Also, and this may be relevant, the GtkFileChooserDialog API seems to be more or less identical in gtk+2 and gtk+3 so there's a fair chance we could write one version of our wrapper function that would work in either case, regardless of what version of GTK the end-user had installed... Maybe...
