me too, and I wrote that code ;) unfortunately there is more than one way to shut down a gladevcp application: - you can kill the window which will get you a destroy event - the linuxcnc script however sends a signal to all running parties to catch the second scenario, see http://www.linuxcnc.org/docs/devel/html/gui/gladevcp.html#_saving_state_when_ctrl_c_is_pressed > > I was able to figure out what it was trying to do by putting print > statements into > /usr/lib/pymodules/python2.6/gladevcp/persistence.py > > What I found was that the getter() returned by get_value() would fail > when the window was being destroyed. yes, it's a chicken-and-egg problem - persistence.py cant do anything anymore if it is called too late in the shutdown process (eg if the widgets are already destroyed there's no way to retrieve their state anymore) let me know how it goes - Michael > > I resolved the problem by putting the 'on_destroy' signal on the same > widget that was being read first.
