-/**
- * 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
- * <code>Display</code> as the argument) are described
- * as <em>top level</em> shells. Instances that do have
- * a parent are described as <em>secondary</em> or
- * <em>dialog</em> shells.
- * <p>
- * Instances are always displayed in one of the maximized,
- * minimized or normal states:
- * <ul>
- * <li>
- * When an instance is marked as <em>maximized</em>, 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 <code>RESIZE</code>) until it is
- * no longer maximized.
- * </li><li>
- * When an instance is in the <em>normal</em> 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).
- * </li><li>
- * When an instance has been marked as <em>minimized</em>,
- * 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.
- * </li>
- * </ul>
- * </p>
- * <p>
- * Note: The styles supported by this class must be treated
- * as <em>HINT</em>s, 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 <code>PRIMARY_MODAL</code> is not supported,
- * it would be upgraded to <code>APPLICATION_MODAL</code>.

- * <dt><b>Events:</b></dt>
- * <dd>Activate, Close, Deactivate, Deiconify, Iconify</dd>

- * Class <code>SWT</code> provides two "convenience constants"
- * for the most commonly required style combinations:
- * <dl>

-/**
- * Instances of this class are selectable user interface
- * objects that represent a range of positive, numeric values.
- * <p>
- * At any given moment, a given slider will have a
- * single <em>selection</em> that is considered to be its
- * value, which is constrained to be within the range of
- * values the slider represents (that is, between its
- * <em>minimum</em> and <em>maximum</em> values).
- * </p><p>
- * Typically, sliders will be made up of five areas:
- * <ol>
- * <li>an arrow button for decrementing the value</li>
- * <li>a page decrement area for decrementing the value by a larger amount</li>
- * <li>a <em>thumb</em> for modifying the value by mouse dragging</li>
- * <li>a page increment area for incrementing the value by a larger amount</li>
- * <li>an arrow button for incrementing the value</li>
- * </ol>
- * Based on their style, sliders are either <code>HORIZONTAL</code>
- * (which have a left facing button for decrementing the value and a
- * right facing button for incrementing it) or <code>VERTICAL</code>
- * (which have an upward facing button for decrementing the value
- * and a downward facing buttons for incrementing it).
- * </p><p>
- * On some platforms, the size of the slider'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 slider will not change.
