| 43 | /** | ||
| 44 | * A <code>Frame</code> is a top-level window with a title and a border. | ||
| 45 | * <p> | ||
| 46 | * The size of the frame includes any area designated for the | ||
| 47 | * border. The dimensions of the border area may be obtained | ||
| 48 | * using the <code>getInsets</code> method, however, since | ||
| 49 | * these dimensions are platform-dependent, a valid insets | ||
| 50 | * value cannot be obtained until the frame is made displayable | ||
| 51 | * by either calling <code>pack</code> or <code>show</code>. | ||
| 52 | * Since the border area is included in the overall size of the | ||
| 53 | * frame, the border effectively obscures a portion of the frame, | ||
| 54 | * constraining the area available for rendering and/or displaying | ||
| 55 | * subcomponents to the rectangle which has an upper-left corner | ||
| 56 | * location of <code>(insets.left, insets.top)</code>, and has a size of | ||
| 57 | * <code>width - (insets.left + insets.right)</code> by | ||
| 58 | * <code>height - (insets.top + insets.bottom)</code>. | ||
| 59 | * <p> | ||
| 60 | * The default layout for a frame is <code>BorderLayout</code>. | ||
| 61 | * <p> | ||
| 62 | * A frame may have its native decorations (i.e. <code>Frame</code> | ||
| 63 | * and <code>Titlebar</code>) turned off | ||
| 64 | * with <code>setUndecorated</code>. This can only be done while the frame | ||
| 65 | * is not {@link Component#isDisplayable() displayable}. | ||
| 66 | * <p> | ||
| 67 | * In a multi-screen environment, you can create a <code>Frame</code> | ||
| 68 | * on a different screen device by constructing the <code>Frame</code> | ||
| 69 | * with {@link #Frame(GraphicsConfiguration)} or | ||
| 70 | * {@link #Frame(String title, GraphicsConfiguration)}. The | ||
| 71 | * <code>GraphicsConfiguration</code> object is one of the | ||
| 72 | * <code>GraphicsConfiguration</code> objects of the target screen | ||
| 73 | * device. | ||
| 74 | * <p> | ||
| 75 | * In a virtual device multi-screen environment in which the desktop | ||
| 76 | * area could span multiple physical screen devices, the bounds of all | ||
| 77 | * configurations are relative to the virtual-coordinate system. The | ||
| 78 | * origin of the virtual-coordinate system is at the upper left-hand | ||
| 79 | * corner of the primary physical screen. Depending on the location | ||
| 80 | * of the primary screen in the virtual device, negative coordinates | ||
| 81 | * are possible, as shown in the following figure. | ||
| 82 | * <p> | ||
| 83 | * <img src="doc-files/MultiScreen.gif" | ||
| 84 | * alt="Diagram of virtual device encompassing three physical screens and one primary physical screen. The primary physical screen | ||
| 85 | * shows (0,0) coords while a different physical screen shows (-80,-100) coords." | ||
| 86 | * ALIGN=center HSPACE=10 VSPACE=7> | ||
| 87 | * <p> | ||
| 88 | * In such an environment, when calling <code>setLocation</code>, | ||
| 89 | * you must pass a virtual coordinate to this method. Similarly, | ||
| 90 | * calling <code>getLocationOnScreen</code> on a <code>Frame</code> | ||
| 91 | * returns virtual device coordinates. Call the <code>getBounds</code> | ||
| 92 | * method of a <code>GraphicsConfiguration</code> to find its origin in | ||
| 93 | * the virtual coordinate system. | ||
| 94 | * <p> | ||
| 95 | * The following code sets the | ||
| 96 | * location of the <code>Frame</code> at (10, 10) relative | ||
| 97 | * to the origin of the physical screen of the corresponding | ||
| 98 | * <code>GraphicsConfiguration</code>. If the bounds of the | ||
| 99 | * <code>GraphicsConfiguration</code> is not taken into account, the | ||
| 100 | * <code>Frame</code> location would be set at (10, 10) relative to the | ||
| 101 | * virtual-coordinate system and would appear on the primary physical | ||
| 102 | * screen, which might be different from the physical screen of the | ||
| 103 | * specified <code>GraphicsConfiguration</code>. | ||
| 104 | * | ||
| 105 | * <pre> | ||
| 106 | * Frame f = new Frame(GraphicsConfiguration gc); | ||
| 107 | * Rectangle bounds = gc.getBounds(); | ||
| 108 | * f.setLocation(10 + bounds.x, 10 + bounds.y); | ||
| 109 | * </pre> | ||
| 110 | * | ||
| 111 | * <p> | ||
| 112 | * Frames are capable of generating the following types of | ||
| 113 | * <code>WindowEvent</code>s: | ||
| 114 | * <ul> | ||
| 115 | * <li><code>WINDOW_OPENED</code> | ||
| 116 | * <li><code>WINDOW_CLOSING</code>: | ||
| 117 | * <br>If the program doesn't | ||
| 118 | * explicitly hide or dispose the window while processing | ||
| 119 | * this event, the window close operation is canceled. | ||
| 120 | * <li><code>WINDOW_CLOSED</code> | ||
| 121 | * <li><code>WINDOW_ICONIFIED</code> | ||
| 122 | * <li><code>WINDOW_DEICONIFIED</code> | ||
| 123 | * <li><code>WINDOW_ACTIVATED</code> | ||
| 124 | * <li><code>WINDOW_DEACTIVATED</code> | ||
| 125 | * <li><code>WINDOW_GAINED_FOCUS</code> | ||
