up to now I worked with the following dnd function. It worked very well, I could drop files and http-adresses from browser.
Now I changed to Linux mint 19.2, dnd with files will not work anymore.
Unfortunately the dnd function aren't well described.
def create_drop_space cb
cb.drag_dest_set( Gtk::DestDefaults::ALL, [['text/plain', 0, 0]], Gdk::DragAction::COPY)
cb.signal_connect('drag_data_received') do |w, context, x, y, data, info, time|
type=data.text[0..4] # what is dropped ?
path=data.text[0..data.text.length] # length of dropped
save_dnd_data data, kwords
