After looking into Fl::dnd() in fl_dnd_x.cxx, I figured it was something like that. I tried to cheat and inject the event using Fl::add_check() which simply did Fl::pushed(dnd_box). Where dnd_box is my widget that does all the DND event handling. That didn't work. So the dnd_box widget simply provides DND receiving capability. I wrote a DND test app that allows one to drag an image file onto a Fl_Box. The DND widget then calls its callback which in turns uses Fl_Shared_Image to load the image and apply it to the Fl_Box. I was successfull at dragging the image off the box onto a konqueror window by calling Fl::dnd() when the FL_DRAG event was seen (The image path was copied to the selection buffer using Fl::copy()). I gave it more thought and I don't think I can do DND sending without doing it within the same FLTK app, atleast not for what I am trying to do anyway. The DND test app works great if the file path is prefixed with a protocol (file://, http://, smb://) that is known to the receiver. That's where my problem begins. I'm trying to drag files off of a MP3 player that uses MTP (libmtp). Konqueror, and I figure Nautilus too, know nothing about MTP. So, the mtp app I wrote will need to download the file from the device before calling Fl::dnd(). But, Fl::dnd() can only be called during a FL_DRAG which would result in a very complicated synchronisation and error handling solution. I think what I'm going to do is stick with the user right-clicking on the table rows (the files) and selecting "Download file(s)". Perhaps in the future I will integrate a file browser plane into the app. This way the drag and drop will only occur within the fltk app which I think is easy to implement. Thanks for you assistance. -- Alvin _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
