| 51 /** | |
| 52 * Instances of this class are responsible for managing the | |
| 53 * connection between SWT and the underlying operating | |
| 54 * system. Their most important function is to implement | |
| 55 * the SWT event loop in terms of the platform event model. | |
| 56 * They also provide various methods for accessing information | |
| 57 * about the operating system, and have overall control over | |
| 58 * the operating system resources which SWT allocates. | |
| 59 * <p> | |
| 60 * Applications which are built with SWT will <em>almost always</em> | |
| 61 * require only a single display. In particular, some platforms | |
| 62 * which SWT supports will not allow more than one <em>active</em> | |
| 63 * display. In other words, some platforms do not support | |
| 64 * creating a new display if one already exists that has not been | |
| 65 * sent the <code>dispose()</code> message. | |
| 66 * <p> | |
| 67 * In SWT, the thread which creates a <code>Display</code> | |
| 68 * instance is distinguished as the <em>user-interface thread</em> | |
| 69 * for that display. | |
| 70 * </p> | |
| 71 * The user-interface thread for a particular display has the | |
| 72 * following special attributes: | |
| 73 * <ul> | |
| 74 * <li> | |
| 75 * The event loop for that display must be run from the thread. | |
| 76 * </li> | |
| 77 * <li> | |
| 78 * Some SWT API methods (notably, most of the public methods in | |
| 79 * <code>Widget</code> and its subclasses), may only be called | |
| 80 * from the thread. (To support multi-threaded user-interface | |
| 81 * applications, class <code>Display</code> provides inter-thread | |
| 82 * communication methods which allow threads other than the | |
| 83 * user-interface thread to request that it perform operations | |
| 84 * on their behalf.) | |
| 85 * </li> | |
| 86 * <li> | |
| 87 * The thread is not allowed to construct other | |
| 88 * <code>Display</code>s until that display has been disposed. | |
| 89 * (Note that, this is in addition to the restriction mentioned | |
| 90 * above concerning platform support for multiple displays. Thus, | |
| 91 * the only way to have multiple simultaneously active displays, | |
| 92 * even on platforms which support it, is to have multiple threads.) | |
| 93 * </li> | |
| 94 * </ul> | |
| 95 * Enforcing these attributes allows SWT to be implemented directly | |
| 96 * on the underlying operating system's event model. This has | |
| 97 * numerous benefits including smaller footprint, better use of | |
| 98 * resources, safer memory management, clearer program logic, | |
| 99 * better performance, and fewer overall operating system threads | |
| 100 * required. The down side however, is that care must be taken | |
| 101 * (only) when constructing multi-threaded applications to use the | |
| 102 * inter-thread communication mechanisms which this class provides | |
| 103 * when required. | |
| 104 * </p><p> | |
| 105 * All SWT API methods which may only be called from the user-interface | |
| 106 * thread are distinguished in their documentation by indicating that | |
| 107 * they throw the "<code>ERROR_THREAD_INVALID_ACCESS</code>" | |
| 108 * SWT exception. | |
