| /** |
| * 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. |
