Extending SimpleApp

You may want to extend SimpleApp to provide a custom layout. Make sure you create three regions with predefined itemId’s that will be used by SimpleApp. You can use the following methods defined by SimpleApp: main_panel_config, status_bar_config, and menu_bar_config, e.g.:

class MySimpleApp < Netzke::Basepack::SimpleApp

  def configuration
    super.merge(
      :items => [my_custom_navigation_config, main_panel_config, menu_bar_config, status_bar_config]
    )
  end

  def my_custom_navigation_config
    {
      :item_id => 'navigation',
      :region => :east,
      :width => 200
    }
  end

  ...
end

The JS side of the component will have those regions referenced as this.mainPanel, this.statusBar, and this.menuBar.
