Their most important function is to implement * the DWT 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 DWT allocates. * <p> * Applications which are built with DWT will <em>almost always</em> * require only a single display. In particular, some platforms * which DWT 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 DWT, 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 DWT 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 DWT 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 DWT 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>" * DWT 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 { /* Windows and Events */ Event [] eventQueue; EventTable eventTable, filterTable; bool disposing; /* Sync/Async Widget Communication */ Synchronizer synchronizer; Thread thread; bool allowTimers, runAsyncMessages; int lastModifiers; Caret currentCaret; Menu menuBar; NSApplication application; NSAutoreleasePool pool; NSPoint cascade = NSPoint(); Callback applicationDelegateCallback3; Callback windowDelegateCallback2, windowDelegateCallback3, windowDelegateCallback4, windowDelegateCallback5; Callback windowDelegateCallback6; Callback dialogCallback3; /* Menus */ // Menu menuBar; // Menu [] menus, popups; // static final int ID_TEMPORARY = 1000; // static final int ID_START = 1001; /* Display Shutdown */ Runnable [] disposeList; /* System Tray */ Tray tray; /* System Resources */ Image errorImage, infoImage, warningImage; Cursor [] cursors = new Cursor [DWT.CURSOR_HAND + 1]; /* Key Mappings. */ static int [] [] KeyTable = [ /* Keyboard and Mouse Masks */ // [58, DWT.ALT], // [56, DWT.SHIFT], // [59, DWT.CONTROL], // [55, DWT.COMMAND], /* Non-Numeric Keypad Keys */ [OS.NSUpArrowFunctionKey, DWT.ARROW_UP], [OS.NSDownArrowFunctionKey, DWT.ARROW_DOWN], [OS.NSLeftArrowFunctionKey, DWT.ARROW_LEFT], [OS.NSRightArrowFunctionKey, DWT.ARROW_RIGHT], [OS.NSPageUpFunctionKey, DWT.PAGE_UP], [OS.NSPageDownFunctionKey, DWT.PAGE_DOWN], [OS.NSHomeFunctionKey, DWT.HOME], [OS.NSEndFunctionKey, DWT.END], // [??, DWT.INSERT], /* Virtual and Ascii Keys */ [OS.NSDeleteCharacter, DWT.BS], // [36, DWT.CR], [OS.NSDeleteFunctionKey, DWT.DEL], // [53, DWT.ESC], // [76, DWT.LF], // [48, DWT.TAB], /* Functions Keys */ [OS.NSF1FunctionKey, DWT.F1], [OS.NSF2FunctionKey, DWT.F2], [OS.NSF3FunctionKey, DWT.F3], [OS.NSF4FunctionKey, DWT.F4], [OS.NSF5FunctionKey, DWT.F5], [OS.NSF6FunctionKey, DWT.F6], [OS.NSF7FunctionKey, DWT.F7], [OS.NSF8FunctionKey, DWT.F8], [OS.NSF9FunctionKey, DWT.F9], [OS.NSF10FunctionKey, DWT.F10], [OS.NSF11FunctionKey, DWT.F11], [OS.NSF12FunctionKey, DWT.F12], [OS.NSF13FunctionKey, DWT.F13], [OS.NSF14FunctionKey, DWT.F14], [OS.NSF15FunctionKey, DWT.F15], /* Numeric Keypad Keys */ // [67, DWT.KEYPAD_MULTIPLY], // [69, DWT.KEYPAD_ADD], // [76, DWT.KEYPAD_CR], // [78, DWT.KEYPAD_SUBTRACT], // [65, DWT.KEYPAD_DECIMAL], // [75, DWT.KEYPAD_DIVIDE], // [82, DWT.KEYPAD_0], // [83, DWT.KEYPAD_1], // [84, DWT.KEYPAD_2], // [85, DWT.KEYPAD_3], // [86, DWT.KEYPAD_4], // [87, DWT.KEYPAD_5], // [88, DWT.KEYPAD_6], // [89, DWT.KEYPAD_7], // [91, DWT.KEYPAD_8], // [92, DWT.KEYPAD_9], // [81, DWT.KEYPAD_EQUAL], /* Other keys */ // [??, DWT.CAPS_LOCK], // [71, DWT.NUM_LOCK], // [??, DWT.SCROLL_LOCK], // [??, DWT.PAUSE], // [??, DWT.BREAK], // [??, DWT.PRINT_SCREEN], [OS.NSHelpFunctionKey, DWT.HELP], ]; static String APP_NAME = "DWT"; static const String ADD_WIDGET_KEY = "dwt.internal.addWidget"; /* Multiple Displays. */ static Display Default; static Display [] Displays = new Display [4]; /* Package Name */ static const String PACKAGE_PREFIX = "dwt.widgets."; /* Timer */ Runnable timerList []; NSTimer nsTimers []; SWTWindowDelegate timerDelegate = cast(SWTWindowDelegate)(new SWTWindowDelegate()).alloc().init(); SWTApplicationDelegate applicationDelegate; /* Display Data */ Object data; String [] keys; Object [] values; /* * TEMPORARY CODE.
