Gtk drop-drag events dont work

Detlef_R · February 16, 2014, 8:48pm

Hi, I want to realize drag-drop events on iconview. I run application
two times and two same widget open. I want to drop a icon from one to
other. drag-drop and drag-data-get signals run but I couldn’t drop the
icon.

drag-drop and drag-data-get signals return some variables I get, but I
coulnd’t get which icon dragged and dropped through signals. I can get
iconview variable through the signals, so I dont get which icon dragged
or dropped.

Can you help me? How can I run drag-drop events?

Thanks.

                        Gdk::DragAction::COPY |
                        Gdk::DragAction::MOVE)
          
          
signal_connect("drag-data-received") do |_widget, context, _x, _y, selection_data, _info, _time|
            context.targets.each do |target|
              if target.name == "test" ||
                 selection_data.type == Gdk::Selection::TYPE_STRING
                data_len = selection_data.data.size
                puts "drag-data-received signal:"
                puts selection_data.data.pack("C#{data_len}")
                puts selection_data.text
              else
                next
              end
            end
