| /** |
| * 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> |
| * The <em>modality</em> of an instance may be specified using |
| * style bits. The modality style bits are used to determine |
| * whether input is blocked for other shells on the display. |
| * The <code>PRIMARY_MODAL</code> style allows an instance to block |
| * input to its parent. The <code>APPLICATION_MODAL</code> style |
| * allows an instance to block input to every other shell in the |
| * display. The <code>SYSTEM_MODAL</code> style allows an instance |
| * to block input to all shells, including shells belonging to |
| * different applications. |
| * </p><p> |
| * Note: The styles supported by this class are 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>. |
| * A modality style may also be "downgraded" to a less |
| * restrictive style. For example, most operating systems |
| * no longer support <code>SYSTEM_MODAL</code> because |
| * it can freeze up the desktop, so this is typically |
| * downgraded to <code>APPLICATION_MODAL</code>. |
| * <dl> |
| * <dt><b>Styles:</b></dt> |
| * <dd>BORDER, CLOSE, MIN, MAX, NO_TRIM, RESIZE, TITLE, ON_TOP, TOOL, SHEET</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> |
| * </p> |
| * <p> |
| * Note: Only one of the styles APPLICATION_MODAL, MODELESS, |
| * PRIMARY_MODAL and SYSTEM_MODAL may be specified. |
