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. - *

- -/** - * Instances of this class are selectable user interface - * objects that represent a range of positive, numeric values. - *

    - * At any given moment, a given scroll bar will have a - * single selection that is considered to be its - * value, which is constrained to be within the range of - * values the scroll bar represents (that is, between its - * minimum and maximum values). - *

    - * Typically, scroll bars will be made up of five areas: - *

      - *
    1. an arrow button for decrementing the value
      2. - *
    2. a page decrement area for decrementing the value by a larger amount
      3. - *
    3. a thumb for modifying the value by mouse dragging
      4. - *
    4. a page increment area for incrementing the value by a larger amount
      5. - *
    5. an arrow button for incrementing the value
      6. - *
    - * Based on their style, scroll bars are either HORIZONTAL - * (which have a left facing button for decrementing the value and a - * right facing button for incrementing it) or VERTICAL - * (which have an upward facing button for decrementing the value - * and a downward facing buttons for incrementing it). - *

    - * On some platforms, the size of the scroll bar's thumb can be - * varied relative to the magnitude of the range of values it - * represents (that is, relative to the difference between its - * maximum and minimum values). Typically, this is used to - * indicate some proportional value such as the ratio of the - * visible area of a document to the total amount of space that - * it would take to display it. SWT supports setting the thumb - * size even if the underlying platform does not, but in this - * case the appearance of the scroll bar will not change. - *

    - * Scroll bars are created by specifying either H_SCROLL, - * V_SCROLL or both when creating a Scrollable. - * They are accessed from the Scrollable using - * getHorizontalBar and getVerticalBar. - *

    - * Note: Scroll bars are not Controls. On some platforms, scroll bars - * that appear as part of some standard controls such as a text or list - * have no operating system resources and are not children of the control. - * For this reason, scroll bars are treated specially. To create a control - * that looks like a scroll bar but has operating system resources, use - * Slider. - *

-/** - * Instances of this class represent the "windows" - * which the desktop or "window manager" is managing. - * Instances that do not have a parent (that is, they - * are built using the constructor, which takes a - * Display as the argument) are described - * as top level shells. Instances that do have - * a parent are described as secondary or - * dialog shells. - *

    - * 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 - * and modality. For example, some window managers only - * support resizable windows and will always assume the - * RESIZE style, even if it is not set. In addition, if a - * modality style is not supported, it is "upgraded" to a - * more restrictive modality style that is supported. For - * example, if PRIMARY_MODAL is not supported, - * it would be upgraded to APPLICATION_MODAL. - *

    - *
    Styles:
    - *
    BORDER, CLOSE, MIN, MAX, NO_TRIM, RESIZE, TITLE
    - *
    APPLICATION_MODAL, MODELESS, PRIMARY_MODAL, SYSTEM_MODAL
    - *
    Events:
    - *
    Activate, Close, Deactivate, Deiconify, Iconify
    - *
    - * 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) - *
