nit: class forward declarations should be at top of the file, not inside the
class.

In this case it's an internal class that needs to be forward declared for the
map below.

+  typedef std::map<chromeos::BrowserView*, NotificationTrayButton*>
+      TrayButtonMap;
+
+  // Protected methods from StatusIcon.
+  virtual void UpdatePlatformContextMenu(ui::MenuModel* model) OVERRIDE;

+  void Clicked();
+
+  // Notification registrar for listening to browser window events.
+  content::NotificationRegistrar registrar_;
+
+  // Map of tray icons for each browser window.
+  TrayButtonMap tray_button_map_;
+
+  // Notification balloon.
+  DesktopNotificationBalloon notification_;
+
+  // A copy of the last set image. Required to initialize the tray icon
+  // in any new browser windows.
+  scoped_ptr<SkBitmap> last_image_;
