Class Shell - * shares a significant amount of code with this class, - * and is a subclass. - *

    - * IMPORTANT: This class was intended to be abstract and - * should never be referenced or instantiated. - * Instead, the class Shell should be used. - *

    - *

    - * Instances are always displayed in one of the maximized, - * minimized or normal states: - *

      - *
    • - * When an instance is marked as maximized, the - * window manager will typically resize it to fill the - * entire visible area of the display, and the instance - * is usually put in a state where it can not be resized - * (even if it has style RESIZE) until it is - * no longer maximized. - *
    • - * When an instance is in the normal state (neither - * maximized or minimized), its appearance is controlled by - * the style constants which were specified when it was created - * and the restrictions of the window manager (see below). - *
    • - * When an instance has been marked as minimized, - * its contents (client area) will usually not be visible, - * and depending on the window manager, it may be - * "iconified" (that is, replaced on the desktop by a small - * simplified representation of itself), relocated to a - * distinguished area of the screen, or hidden. Combinations - * of these changes are also possible. - *
      • - *
    - *

    - * Note: The styles supported by this class must be treated - * as HINTs, since the window manager for the - * desktop on which the instance is visible has ultimate - * control over the appearance and behavior of decorations. - * For example, some window managers only support resizable - * windows and will always assume the RESIZE style, even if - * it is not set. - *
    - *
    Styles:
    - *
    BORDER, CLOSE, MIN, MAX, NO_TRIM, RESIZE, TITLE, ON_TOP, TOOL
    - *
    Events:
    - *
    (none)
    - *
    - * Class SWT provides two "convenience constants" - * for the most commonly required style combinations: - *
    - *
    SHELL_TRIM
    - *
    - * the result of combining the constants which are required - * to produce a typical application top level shell: (that - * is, CLOSE | TITLE | MIN | MAX | RESIZE) - *

    DIALOG_TRIM
    - *
    - * the result of combining the constants which are required - * to produce a typical application dialog shell: (that - * is, TITLE | CLOSE | BORDER) - *

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. - *

    - * Applications which are built with SWT will almost always - * require only a single display. In particular, some platforms - * which SWT supports will not allow more than one active - * display. In other words, some platforms do not support - * creating a new display if one already exists that has not been - * sent the dispose() message. - *

    - * In SWT, the thread which creates a Display - * instance is distinguished as the user-interface thread - * for that display. - *

    - * The user-interface thread for a particular display has the - * following special attributes: - *
      - *
    • - * The event loop for that display must be run from the thread. - *
      • - *
    • - * Some SWT API methods (notably, most of the public methods in - * Widget and its subclasses), may only be called - * from the thread. (To support multi-threaded user-interface - * applications, class Display provides inter-thread - * communication methods which allow threads other than the - * user-interface thread to request that it perform operations - * on their behalf.) - *
      • - *
    • - * The thread is not allowed to construct other - * Displays 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.) - *
      • - *
    - * 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. - *

    - * 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 "ERROR_THREAD_INVALID_ACCESS" - * SWT exception. - *
