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. - * </p><p> - * IMPORTANT: This class is not intended to be subclassed. - * </p> - * - * @see Decorations - * @see SWT - * @see <a href="http://www.eclipse.org/swt/snippets/#shell">Shell snippets</a> - * @see <a href="http://www.eclipse.org/swt/examples.php">SWT Example: ControlExample</a> - * @see <a href="http://www.eclipse.org/swt/">Sample code and further information</a> - */ -public class Shell extends Decorations { - Control lastActive; - boolean closing; - boolean moved, resized, opened, fullScreen, modified, center; - int oldX, oldY, oldWidth, oldHeight; - int oldWindowStyle, oldWindowState; - -/** - * Constructs a new instance of this class.
