In Sugar, there's always one and only one active activity. You can see which it is by looking at the icon below the XO in the favorites view or by looking at the selected activity button in the top frame. This is the activity that will be brought to the front when you go to the Activity zoom level. I'm guessing Measure uses its "active activity" status to decide if it should update itself or not, but from earlier emails I think the desired behavior is rather to stop updating while the activity window is not visible. For this, the activity author can use the information that the window manager (or is it X?) provides to each top level window, in pygtk: http://pygtk.org/docs/pygtk/class-gtkwidget.html#signal-gtkwidget--visibility-notify-event Just listen for that signal and check the value of event.state, it can be one of gtk.gdk.VISIBILITY_FULLY_OBSCURED, gtk.gdk.VISIBILITY_PARTIAL or gtk.gdk.VISIBILITY_UNOBSCURED. You will want to stop updating the screen when fully obscured and update it otherwise. Faisal, could you please update the almanac with this info?
