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

3232 * above conditions and its {@code GraphicsConfiguration} is

3234 * <p>
3235 * <b>Note</b>: If the lower edge of the window is out of the screen,
3236 * then the window is placed to the side of the {@code Component}
3237 * that is closest to the center of the screen. So if the
3238 * component is on the right part of the screen, the window
3239 * is placed to its left, and vice versa.
