| === What is the Window System? |
| |
| The windowing system is what creates the main application window, and makes it |
| possible to open components in the UI. The API for the windowing system is in the package |
| `org.openide.windows`. The implementation of the windowing system is in the module |
| `org.netbeans.core.windows` (core.windows in Mercurial repository, was core/windows in CVS). |
| |
| The window system defines link:DevFaqWindowsMode.asciidoc[Mode]s which are places in the main window |
| occupied by tabbed containers. link:DevFaqWindowsTopComponents.asciidoc[TopComponent]s are GUI |
| components (instances or subclasses of `org.openide.windows.TopComponent` which |
| can be put into these tabbed containers. |
| |
| There is a link:DevFaqModulesDeclarativeVsProgrammatic.asciidoc[programmatic API] for creating/opening |
| TopComponents - this is useful for testing components under development - just create an Action which |
| calls `new MyTopComponent().open()` to quickly try out GUI components. |
| |
| However, the main API modules use the link:DevFaqWindowsWstcrefAndFriends.asciidoc[declarative XML Window System API] to install their components, for the following reasons: |
| |
| * Scalability: Components do not need to be created/deserialized unless they really need to be opened |
| * Singletonization: You wouldn't want to have 5 Projects tabs in the IDE. Using the XML API correctly, you can easily refer to the singleton instance of your component once it's instantiated (almost) for free. |
| * Persistence: The window system associates components with unique IDs; to properly persist your component across sessions, you need to use the XML APIs |
