I don't know what you mean by "dragging the last row away". On this system, dragging any row out of the window returns the row back to the treeview as if the dragging operation was not valid. No row is really added or removed in that case. It just looks like a no-op so no signal handlers would be called because no row is modified. > Still I'd like to know whether it is the supposed way to handle DND in > TreeView. I think the error is in the code inside the signal handlers because the modified code I sent you outputs the statements I inserted when *any* row is moved anywhere in the treeview (this is true as much for the last row as for any other -- at least on this system). . I don't know enough about what you're trying to do, but I still think it's in the logic of the handlers. If all else fails, if you do what Jonner already suggested (i.e. write parallel C and C++ code to see if there is a difference in behavior), you'll probably have better success at finding the bug, if any. You should test in C and C++. If the C and C++ code are equivalent and you find a difference in behavior then I would say, yes file a bug. -- José Alburquerque _______________________________________________ gtkmm-list mailing list gtkmm-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtkmm-list
