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. - * </p> - * <dl> - * <dt><b>Styles:</b></dt> - * <dd>(none)</dd> - * <dt><b>Events:</b></dt> - * <dd>Close, Dispose, Settings</dd> - * </dl> - * <p> - * IMPORTANT: This class is <em>not</em> intended to be subclassed. - * </p> - * @see #syncExec - * @see #asyncExec - * @see #wake - * @see #readAndDispatch - * @see #sleep - * @see Device#dispose - * @see <a href="http://www.eclipse.org/swt/snippets/#display">Display snippets</a> - * @see <a href="http://www.eclipse.org/swt/">Sample code and further information</a> - * @noextend This class is not intended to be subclassed by clients. - */ - -public class Display extends Device { - - /** - * the handle to the OS message queue - * (Warning: This field is platform dependent) - * <p> - * <b>IMPORTANT:</b> This field is <em>not</em> part of the SWT - * public API.
