RAD Studio
Using Action Lists

Note: The contents of this topic apply to setting up toolbars and menus for cross-platform development. For Windows development you can also use the methods described here. However, using action bands instead is simpler and offers more options. The action lists will be handled automatically by the Action Manager. See Organizing actions for toolbars and menus for details.
Action lists maintain a list of actions that your application can take in response to something a user does. By using action objects, you centralize the functions performed by your application from the user interface. This lets you share common code for performing actions (for example, when a toolbar button and menu item do the same thing), as well as providing a single, centralized way to enable and disable actions depending on the state of your application.
