You're making two mistakes:

(1) failing to add the dock-widget to a (default) dock-area
(2) trying implement your own toggle view action

Qt already has (2) covered, and does a much better job of it than your 
example code currently does (for one thing, it handles closing of the 
dock-widget by the user).

So comment out *all* the toggle_dock_widget_action code in your example 
(including the signal handler), and put the following in initUI:

         self.filter_widget = MyDockWidget()
         self.toggle_dock_widget_action = 
         self.toggle_dock_widget_action.setText('Show/Hide Filter Pane')
