Their most important function is to implement - * the SWT event loop in terms of the platform event model. - * They also provide various methods for accessing information - * about the operating system, and have overall control over - * the operating system resources which SWT allocates. - * <p> - * Applications which are built with SWT will <em>almost always</em> - * require only a single display. In particular, some platforms - * which SWT supports will not allow more than one <em>active</em> - * display. In other words, some platforms do not support - * creating a new display if one already exists that has not been - * sent the <code>dispose()</code> message. - * <p> - * In SWT, the thread which creates a <code>Display</code> - * instance is distinguished as the <em>user-interface thread</em> - * for that display. - * </p> - * The user-interface thread for a particular display has the - * following special attributes: - * <ul> - * <li> - * The event loop for that display must be run from the thread. - * </li> - * <li> - * Some SWT API methods (notably, most of the public methods in - * <code>Widget</code> and its subclasses), may only be called - * from the thread. (To support multi-threaded user-interface - * applications, class <code>Display</code> provides inter-thread - * communication methods which allow threads other than the - * user-interface thread to request that it perform operations - * on their behalf.) - * </li> - * <li> - * The thread is not allowed to construct other - * <code>Display</code>s until that display has been disposed. - * (Note that, this is in addition to the restriction mentioned - * above concerning platform support for multiple displays. Thus, - * the only way to have multiple simultaneously active displays, - * even on platforms which support it, is to have multiple threads.) - * </li> - * </ul> - * Enforcing these attributes allows SWT to be implemented directly - * on the underlying operating system's event model. This has - * numerous benefits including smaller footprint, better use of - * resources, safer memory management, clearer program logic, - * better performance, and fewer overall operating system threads - * required.
