65 * A <code>Window</code> object is a top-level window with no borders and no
66 * menubar.
67 * The default layout for a window is <code>BorderLayout</code>.
68 * <p>
69 * A window must have either a frame, dialog, or another window defined as its
70 * owner when it's constructed.
71 * <p>
72 * In a multi-screen environment, you can create a <code>Window</code>
73 * on a different screen device by constructing the <code>Window</code>
74 * with {@link #Window(Window, GraphicsConfiguration)}. The
75 * <code>GraphicsConfiguration</code> object is one of the
76 * <code>GraphicsConfiguration</code> objects of the target screen device.
77 * <p>
78 * In a virtual device multi-screen environment in which the desktop
79 * area could span multiple physical screen devices, the bounds of all
80 * configurations are relative to the virtual device coordinate system.
81 * The origin of the virtual-coordinate system is at the upper left-hand
82 * corner of the primary physical screen. Depending on the location of
83 * the primary screen in the virtual device, negative coordinates are
84 * possible, as shown in the following figure.
85 * <p>
86 * <img src="doc-files/MultiScreen.gif"
87 * alt="Diagram shows virtual device containing 4 physical screens. Primary physical screen shows coords (0,0), other screen shows (-80,-100)."
88 * ALIGN=center HSPACE=10 VSPACE=7>
89 * <p>
90 * In such an environment, when calling <code>setLocation</code>,
91 * you must pass a virtual coordinate to this method. Similarly,
92 * calling <code>getLocationOnScreen</code> on a <code>Window</code> returns
93 * virtual device coordinates. Call the <code>getBounds</code> method
94 * of a <code>GraphicsConfiguration</code> to find its origin in the virtual
95 * coordinate system.
96 * <p>
97 * The following code sets the location of a <code>Window</code>
98 * at (10, 10) relative to the origin of the physical screen
99 * of the corresponding <code>GraphicsConfiguration</code>. If the
100 * bounds of the <code>GraphicsConfiguration</code> is not taken
101 * into account, the <code>Window</code> location would be set
102 * at (10, 10) relative to the virtual-coordinate system and would appear
103 * on the primary physical screen, which might be different from the
104 * physical screen of the specified <code>GraphicsConfiguration</code>.
105 *
106 * <pre>
107 * Window w = new Window(Window owner, GraphicsConfiguration gc);
108 * Rectangle bounds = gc.getBounds();
109 * w.setLocation(10 + bounds.x, 10 + bounds.y);
110 * </pre>
111 *
112 * <p>
113 * Note: the location and size of top-level windows (including
114 * <code>Window</code>s, <code>Frame</code>s, and <code>Dialog</code>s)
115 * are under the control of the desktop's window management system.
116 * Calls to <code>setLocation</code>, <code>setSize</code>, and
117 * <code>setBounds</code> are requests (not directives) which are
118 * forwarded to the window management system. Every effort will be
119 * made to honor such requests. However, in some cases the window
120 * management system may ignore such requests, or modify the requested
121 * geometry in order to place and size the <code>Window</code> in a way
122 * that more closely matches the desktop settings.
123 * <p>
124 * Due to the asynchronous nature of native event handling, the results
125 * returned by <code>getBounds</code>, <code>getLocation</code>,
126 * <code>getLocationOnScreen</code>, and <code>getSize</code> might not
127 * reflect the actual geometry of the Window on screen until the last
128 * request has been processed. During the processing of subsequent
129 * requests these values might change accordingly while the window
130 * management system fulfills the requests.
131 * <p>
132 * An application may set the size and location of an invisible
133 * {@code Window} arbitrarily, but the window management system may
134 * subsequently change its size and/or location when the
135 * {@code Window} is made visible. One or more {@code ComponentEvent}s
136 * will be generated to indicate the new geometry.
137 * <p>
138 * Windows are capable of generating the following WindowEvents:
139 * WindowOpened, WindowClosed, WindowGainedFocus, WindowLostFocus.

2145 * <code>false</code> the always-on-top state is set to normal. The
2146 * window remains in the top-most position but it`s z-order can be
2147 * changed as for any other window. Calling this method with a value
2148 * of <code>false</code> on a window that has a normal state has no
