| 64 | /** | ||
| 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. | ||
