Solve the following python programming problem given the following code:
def _wx_initialize_view_dock_control(self, view, view_dock_control) : 
    " Initializes a view dock control.

        fixme: We only need this method because of a problem with the dock
        window API in the 'SetStructureHandler' class. Currently we do not get
        a reference to the dock control in 'resolve_id' and hence we cannot set
        up the 'on_close' and trait change handlers etc.

        " 
    view_dock_control.set_name (view.name) 
    if (hasattr (view, 'ui') and (view_dock_control.ui is not None)) : 
        if (view.ui.view is not None) : 
            view_dock_control.export = view.ui.view.export 
view_dock_control.dockable = DockableViewElement (should_close = True, ui = view.ui) 
view_dock_control.on_close = self._wx_on_view_closed 
    def on_id_changed(view, trait_name, old, new) : 
        view_dock_control.id = view.id 
        return 
view.on_trait_change (on_id_changed, 'id') 
    def on_name_changed(view, trait_name, old, new) : 
        view_dock_control.set_name (view.name) 
        return 
view.on_trait_change (on_name_changed, 'name') 
    def on_activated_changed(view_dock_control, trait_name, old, new) : 
        if (view_dock_control._view is not None) : 
            view_dock_control._view.set_focus () 
return 
view_dock_control.on_trait_change (on_activated_changed, 'activated') 
    return
