- * Instances of this class are responsible for managing the
- * connection between SWT and the underlying operating
- * system. 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. The down side however, is that care must be taken
- * (only) when constructing multi-threaded applications to use the
- * inter-thread communication mechanisms which this class provides
- * when required.
- * </p><p>
- * All SWT API methods which may only be called from the user-interface
- * thread are distinguished in their documentation by indicating that
- * they throw the "<code>ERROR_THREAD_INVALID_ACCESS</code>"
- * SWT exception.
