int drag_data_received( GTK2.TreePath path, GTK2.SelectionData sel ); //! Asks to insert a row before the path dest, deriving the contents of the //! row from the sel. If this dest is outside the tree so that inserting //! before it is impossible, false will be returned. Also, false may be //! returned if the new row is not created for some model-specific reason. //! //! int row_drop_possible( GTK2.TreePath path, GTK2.SelectionData sel ); //! Determines whether a drop is possible before past, at the same depth as //! path. i.e., can we drop the data in sel at that location. path does not //! have to exist; the return value will almost certainly be false if the //! parent of path doesn't exist, though. //! //!
