So I started to playing around with GTK Drag and drop, read couple of articles and managed to get what I wanted - path to dragged file/directory when dropping it on rows of treeview but I can't seem to get to highlight row that mouse pointer is above.

I used:

Code:
gtk_drag_dest_set(users_view,(GtkDestDefaults)(GTK_DEST_DEFAULT_ALL | GTK_DEST_DEFAULT_HIGHLIGHT),typ_drag,1, GDK_ACTION_COPY);

g_signal_connect(G_OBJECT(users_view),"drag_data_received",G_CALLBACK(drag_data_received_handl),NULL);

void
drag_data_received_handl
(GtkWidget *widget, GdkDragContext *context, gint x, gint y,
        GtkSelectionData *selection_data, guint target_type, guint time,
        gpointer data)
{
   gchar** names;
   gchar* name;

      

        /* Deal with what we are given from source */
        if((selection_data != NULL) && (gtk_selection_data_get_length(selection_data) >= 0))
        {

                /* Check that we got the format we can use */
                switch (target_type)
                {
            case 1:
               {
                  names = gtk_selection_data_get_uris(selection_data);
                  name = g_filename_from_uri(names[0],NULL,NULL);
                  std::cout << name << std::endl;
                  g_strfreev(names);
                  g_free(name);
                               
                                break;
               }

                        default:
                                g_print("Something else");
                }

        }


        gtk_drag_finish (context, TRUE,FALSE, time);
}


EDIT: Now I see the problem, usually You should use drag-motion signal and then highlight widget with highlight drag function but because I use GTK_DEST_DEFAULT_ALL GTK autmatically sets all drag and drops events and therfore drag-motion is never called in my code.

Is there a soultion to fix it without writting whole DnD by myself?
