In the following code, variable src_actions of type GTKDragAction is returned:

padgettr/rfm/blob/76fed73021058aad0d4c184cd94a9483be940734/rfm.c#L1450

      
        
            GdkDragAction src_actions;
            GdkDragAction selected_action;
            gint bx,by;
            gchar *dest_path=NULL;
            RFM_dndMenu *dndMenu=g_object_get_data(G_OBJECT(window), "rfm_dnd_menu");
            
            
/* src_actions holds the bit mask of possible actions if
             * suggested_action is GDK_ACTION_ASK. We ignore suggested
             * action and always ask - see drag_motion_handl() below.
             */
            src_actions=gdk_drag_context_get_actions(context);
            selected_action=gdk_drag_context_get_selected_action(context);
            
            
if (selected_action!=GDK_ACTION_ASK)
               g_warning ("drag_data_received_handl(): selected action is not ask!\n");
            
            
selection_length=gtk_selection_data_get_length(selection_data);
            if (target_type==TARGET_URI_LIST && selection_length>0) {
               /* Setup destination */
               gtk_icon_view_convert_widget_to_bin_window_coords(GTK_ICON_VIEW(widget), x, y, &bx, &by);
               tree_path=gtk_icon_view_get_path_at_pos(GTK_ICON_VIEW(widget), bx, by);

and later in this function, src_actions is used in conditional expression.

the src_actions variable has value:

GDK_ACTION_ASK | GDK_ACTION_COPY | GDK_ACTION_MOVE

i want to add value GDK_ACTION_LINK into the returned src_actions, how?

i had also created an issue here: issue when adding Link option besides copy and move in drag and drop · Issue #2 · padgettr/rfm · GitHub
