/*--------------------------- nsIAppShellComponent -----------------------------
| This interface describes the fundamental communications between the |
| application shell and its dynamically installable "components." Components |
| are self-contained bits of browser client application functionality. They |
| range in size from the general-purpose "Find dialog" up to the "browser." |
| |
| The interface has three main purposes: |
| o It provides a means for the app shell to identify and load components |
| dynamically. |
| o It enables those components to contribute to the browser client |
| application User Interface (e.g., by adding menu options, etc.). |
| o It gives the app shell (and other components) a way to broadcast |
| interesting events to other components. |
| |
| [Currently, only the first purpose is exploited.] |
| |
| All app shell components must: |
| 1. Implement this interface. |
| 2. Publish and implement additional interfaces, as necessary, to |
| support component-specific function. For example, the "find |
| component" also implements the nsIFindComponent interface which |
| adds functions specific to that component. |
| 3. Register (using the Mozilla XPCOM component registration facilities) |
| using a ContractID of the form: |
| @mozilla.org/appshell/component/foo;1 |
| where "foo" is a component-specific identifier (which should match the |
| component-specific interface name). |
| |
| The app shell will instantiate each such component at application start-up |
| and invoke the components Initialize() member function, passing a pointer |
| to the app shell and to the command-line service corresponding to the |
| command-line arguments used to start the app shell. |
| |
| The component should implement this function as necessary. Typically, a |
| component will register interest in an appropriate set of events (e.g., |
| browser windows opening). Some components, such as the browser, will |
| examine the command line argements and open windows. |
| |
| Upon return, the app shell will maintain a reference to the component and |
| notify it when events of interest occur. |
