准备理一下菜单和工具栏相关的组件

TMainMenu                                           <- TMenu <- TComponent
TPopupMenu                                          <- TMenu <- TComponent
TPopupActionBar                       <- TPopupMenu <- TMenu <- TComponent

TActionList                             <- TCustomActionList <- TComponent
TActionManager  <- TCustomActionManager <- TCustomActionList <- TComponent

TControlBar <- TCustomControlBar <- TCustomControl <- TWinControl
TStatusBar                     <- TCustomStatusBar <- TWinControl
TCoolBar                            <- TToolWindow <- TWinControl
TToolBar                            <- TToolWindow <- TWinControl

TActionToolBar                                 <- TCustomActionToolBar <- TCustomActionDockBar <- TCustomActionBar <- TToolWindow <- TWinControl
TActionMainMenuBar <- TCustomActionMainMenuBar <- TCustomActionMenuBar <- TCustomActionDockBar <- TCustomActionBar <- TToolWindow <- TWinControl
