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

101 * <dt><b>Events:</b></dt>
102 * <dd>Activate, Close, Deactivate, Deiconify, Iconify</dd>
103 * </dl>
104 * Class <code>DWT</code> provides two "convenience constants"
105 * for the most commonly required style combinations:
106 * <dl>
107 * <dt><code>SHELL_TRIM</code></dt>
108 * <dd>
109 * the result of combining the constants which are required
110 * to produce a typical application top level shell: (that
111 * is, <code>CLOSE | TITLE | MIN | MAX | RESIZE</code>)
112 * </dd>
113 * <dt><code>DIALOG_TRIM</code></dt>
114 * <dd>
115 * the result of combining the constants which are required
116 * to produce a typical application dialog shell: (that
117 * is, <code>TITLE | CLOSE | BORDER</code>)
118 * </dd>
119 * </dl>
120 * </p>
121 * <p>
122 * Note: Only one of the styles APPLICATION_MODAL, MODELESS,
123 * PRIMARY_MODAL and SYSTEM_MODAL may be specified.
