    Remarks
    Modules are automatically notified whenever one of its panes are activated, deactivated, opened, or closed. This means a Module doesn’t have to listen to the Framework’s ActivePaneChanged event and from here filter for its panes; instead, Modules are given direct notification that one of their panes changed.
