| 51 * Instances of this class represent the "windows" | |
| 52 * which the desktop or "window manager" is managing. | |
| 53 * Instances that do not have a parent (that is, they | |
| 54 * are built using the constructor, which takes a | |
| 55 * <code>Display</code> as the argument) are described | |
| 56 * as <em>top level</em> shells. Instances that do have | |
| 57 * a parent are described as <em>secondary</em> or | |
| 58 * <em>dialog</em> shells. | |
| 59 * <p> | |
| 60 * Instances are always displayed in one of the maximized, | |
| 61 * minimized or normal states: | |
| 62 * <ul> | |
| 63 * <li> | |
| 64 * When an instance is marked as <em>maximized</em>, the | |
| 65 * window manager will typically resize it to fill the | |
| 66 * entire visible area of the display, and the instance | |
| 67 * is usually put in a state where it can not be resized | |
| 68 * (even if it has style <code>RESIZE</code>) until it is | |
| 69 * no longer maximized. | |
| 70 * </li><li> | |
| 71 * When an instance is in the <em>normal</em> state (neither | |
| 72 * maximized or minimized), its appearance is controlled by | |
| 73 * the style constants which were specified when it was created | |
| 74 * and the restrictions of the window manager (see below). | |
| 75 * </li><li> | |
| 76 * When an instance has been marked as <em>minimized</em>, | |
| 77 * its contents (client area) will usually not be visible, | |
| 78 * and depending on the window manager, it may be | |
| 79 * "iconified" (that is, replaced on the desktop by a small | |
| 80 * simplified representation of itself), relocated to a | |
| 81 * distinguished area of the screen, or hidden. Combinations | |
| 82 * of these changes are also possible. | |
| 83 * </li> | |
| 84 * </ul> | |
| 85 * </p><p> | |
| 86 * The <em>modality</em> of an instance may be specified using | |
| 87 * style bits. The modality style bits are used to determine | |
| 88 * whether input is blocked for other shells on the display. | |
| 89 * The <code>PRIMARY_MODAL</code> style allows an instance to block | |
| 90 * input to its parent. The <code>APPLICATION_MODAL</code> style | |
| 91 * allows an instance to block input to every other shell in the | |
| 92 * display. The <code>SYSTEM_MODAL</code> style allows an instance | |
| 93 * to block input to all shells, including shells belonging to | |
| 94 * different applications. | |
| 95 * </p><p> | |
| 96 * Note: The styles supported by this class are treated | |
| 97 * as <em>HINT</em>s, since the window manager for the | |
| 98 * desktop on which the instance is visible has ultimate | |
| 99 * control over the appearance and behavior of decorations | |
| 100 * and modality. For example, some window managers only | |
| 101 * support resizable windows and will always assume the | |
| 102 * RESIZE style, even if it is not set. In addition, if a | |
| 103 * modality style is not supported, it is "upgraded" to a | |
| 104 * more restrictive modality style that is supported. For | |
| 105 * example, if <code>PRIMARY_MODAL</code> is not supported, | |
| 106 * it would be upgraded to <code>APPLICATION_MODAL</code>. | |
| 107 * A modality style may also be "downgraded" to a less | |
| 108 * restrictive style. For example, most operating systems | |
| 109 * no longer support <code>SYSTEM_MODAL</code> because | |
| 110 * it can freeze up the desktop, so this is typically | |
| 111 * downgraded to <code>APPLICATION_MODAL</code>. | |
| 112 * <dl> | |
| 113 * <dt><b>Styles:</b></dt> | |
| 114 * <dd>BORDER, CLOSE, MIN, MAX, NO_TRIM, RESIZE, TITLE, ON_TOP, TOOL</dd> | |

| 122 * <dt><code>SHELL_TRIM</code></dt> | |
| 123 * <dd> | |
| 124 * the result of combining the constants which are required | |

| 128 * <dt><code>DIALOG_TRIM</code></dt> | |
