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 */ public class Display : Device { /* Events Dispatching and Callback */ int gdkEventCount;
