I saw that, but I can't use the keyboard (arrows are affected to other functions). > Without further information I assume that your problem is that you have > a handler for that signal but you don't want that handler to be executed > if you change the value by program (using "set_value()").

When I change the value of the first, I need to refresh the second, and changing the second must update the first. But the way they are refreshed is not symetrical; that's why I need to stop the signal when the value is changed from teh code (with set_value() method). You idea seems fine, but I don't see how to implement it, as I use glade for building gui, and wTree.signal_autoconnect(myDict) to connect signals... Any idea? It is also possible to block signals, but this needs to know the handler_id, which is not possible using glade, am I wrong: http://www.pygtk.org/pygtk2tutorial/ch-MovingOn.html#sec-MoreOnSignalHandlers -- Frédéric http://www.gbiloba.org _______________________________________________ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
