We'd need to see your "scc.glade" file to be sure, but basically, calling the "show" method on the "w_cadcli" object only shows it, not the objects it contains. Again, to be clear, showing a container object doesn't automatically show the objects it contains. In glade, use the "common" tab of the property editor to make sure that the "visible" property is set to "Yes" for all of the widgets in the windows you want to show. In general, if you always do that, you'll be able to show or hide the entire window by simply calling "show" or "hide" on the window object, like you're trying to do.
But this is just a guess; post your "scc.glade" file if the above advice doesn't work. Greg -- http://mail.python.org/mailman/listinfo/python-list
