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</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 { - Menu activeMenu; - boolean fullScreen, wasMaximized, modified; - Control lastActive; - private QMainWindow mainWindow; - private QDialog dialogWindow; - private QStyle oldStyle; - - /** - * Constructs a new instance of this class.
