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:</p> * <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> * 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>.</p> * <dl> * <dt><b>Styles:</b></dt> * <dd>BORDER, CLOSE, MIN, MAX, NO_MOVE, 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> * <p> * Class <code>SWT</code> provides two "convenience constants" * for the most commonly required style combinations:</p> * <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> * Note: Only one of the styles APPLICATION_MODAL, MODELESS, * PRIMARY_MODAL and SYSTEM_MODAL may be specified. * </p><p> * IMPORTANT: This class is <em>not</em> 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> * @noextend This class is not intended to be subclassed by clients. */ public class Shell extends Decorations { long shellHandle, tooltipsHandle, tooltipWindow, group, modalGroup; boolean mapped, moved, resized, opened, fullScreen, showWithParent, modified, center; int oldX, oldY, oldWidth, oldHeight; int minWidth, minHeight; Control lastActive; ToolTip[] toolTips; boolean ignoreFocusOut, ignoreFocusIn; boolean ignoreFocusOutAfterGrab, grabbedFocus; Region originalRegion; static final int MAXIMUM_TRIM = 128; static final int BORDER = 3; /** * Constructs a new instance of this class.
