| /**
|
| * 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>.
|
| * <dl>
|
| * <dt><b>Styles:</b></dt>
|
| * <dd>BORDER, CLOSE, MIN, MAX, NO_TRIM, RESIZE, TITLE</dd>
|
| * <dd>APPLICATION_MODAL, MODELESS, PRIMARY_MODAL, SYSTEM_MODAL</dd>
|
| * <dt><b>Events:</b></dt>
|
| * <dd>Activate, Close, Deactivate, Deiconify, Iconify</dd>
|
| * </dl>
|
| * Class <code>SWT</code> provides two "convenience constants"
|
| * for the most commonly required style combinations:
|
| * <dl>
|
| * <dt><code>SHELL_TRIM</code></dt>
|
| * <dd>
|
| * the result of combining the constants which are required
|
| * to produce a typical application top level shell: (that
|
| * is, <code>CLOSE | TITLE | MIN | MAX | RESIZE</code>)
|
| * </dd>
|
| * <dt><code>DIALOG_TRIM</code></dt>
|
| * <dd>
|
| * the result of combining the constants which are required
|
| * to produce a typical application dialog shell: (that
|
| * is, <code>TITLE | CLOSE | BORDER</code>)
|
| * </dd>
|
| * </dl>
