|
83 |
* The diagram at right shows the structure of a <code>JRootPane</code>. |
|
84 |
* A <code>JRootpane</code> is made up of a <code>glassPane</code>, |
|
85 |
* an optional <code>menuBar</code>, and a <code>contentPane</code>. |
|
86 |
* (The <code>JLayeredPane</code> manages the <code>menuBar</code> |
|
87 |
* and the <code>contentPane</code>.) |
|
88 |
* The <code>glassPane</code> sits over the top of everything, |
|
89 |
* where it is in a position to intercept mouse movements. |
|
90 |
* Since the <code>glassPane</code> (like the <code>contentPane</code>) |
|
91 |
* can be an arbitrary component, it is also possible to set up the |
|
92 |
* <code>glassPane</code> for drawing. Lines and images on the |
|
93 |
* <code>glassPane</code> can then range |
|
94 |
* over the frames underneath without being limited by their boundaries. |
|
95 |
* <p> |
|
96 |
* Although the <code>menuBar</code> component is optional, |
|
97 |
* the <code>layeredPane</code>, <code>contentPane</code>, |
|
98 |
* and <code>glassPane</code> always exist. |
|
99 |
* Attempting to set them to <code>null</code> generates an exception. |
|
100 |
* <p> |
|
101 |
* To add components to the <code>JRootPane</code> (other than the |
|
102 |
* optional menu bar), you add the object to the <code>contentPane</code> |
|
103 |
* of the <code>JRootPane</code>, like this: |
|
104 |
* <pre> |
|
105 |
* rootPane.getContentPane().add(child); |
|
106 |
* </pre> |
|
107 |
* The same principle holds true for setting layout managers, removing |
|
108 |
* components, listing children, etc. All these methods are invoked on |
|
109 |
* the <code>contentPane</code> instead of on the <code>JRootPane</code>. |
|
110 |
* <blockquote> |
|
111 |
* <b>Note:</b> The default layout manager for the <code>contentPane</code> is |
|
112 |
* a <code>BorderLayout</code> manager. However, the <code>JRootPane</code> |
|
113 |
* uses a custom <code>LayoutManager</code>. |
|
114 |
* So, when you want to change the layout manager for the components you added |
|
115 |
* to a <code>JRootPane</code>, be sure to use code like this: |
|
116 |
* <pre> |
|
117 |
* rootPane.getContentPane().setLayout(new BoxLayout()); |
|
118 |
* </pre></blockquote> |
|
119 |
* If a <code>JMenuBar</code> component is set on the <code>JRootPane</code>, |
|
120 |
* it is positioned along the upper edge of the frame. |
|
121 |
* The <code>contentPane</code> is adjusted in location and size to |
|
122 |
* fill the remaining area. |
|
123 |
* (The <code>JMenuBar</code> and the <code>contentPane</code> are added to the |
|
124 |
* <code>layeredPane</code> component at the |
|
125 |
* <code>JLayeredPane.FRAME_CONTENT_LAYER</code> layer.) |
|
126 |
* <p> |
|
127 |
* The <code>layeredPane</code> is the parent of all children in the |
|
128 |
* <code>JRootPane</code> -- both as the direct parent of the menu and |
|
129 |
* the grandparent of all components added to the <code>contentPane</code>. |
|
130 |
* It is an instance of <code>JLayeredPane</code>, |
|
131 |
* which provides the ability to add components at several layers. |
|
132 |
* This capability is very useful when working with menu popups, |
|
133 |
* dialog boxes, and dragging -- situations in which you need to place |
|
134 |
* a component on top of all other components in the pane. |
|
135 |
* <p> |
|
136 |
* The <code>glassPane</code> sits on top of all other components in the |
|
137 |
* <code>JRootPane</code>. |
|
138 |
* That provides a convenient place to draw above all other components, |
|
139 |
* and makes it possible to intercept mouse events, |
|
140 |
* which is useful both for dragging and for drawing. |
|
141 |
* Developers can use <code>setVisible</code> on the <code>glassPane</code> |
|
142 |
* to control when the <code>glassPane</code> displays over the other children. |
|
143 |
* By default the <code>glassPane</code> is not visible. |
|
144 |
* <p> |
|
145 |
* The custom <code>LayoutManager</code> used by <code>JRootPane</code> |
|
146 |
* ensures that: |
|
147 |
* <OL> |
|
148 |
* <LI>The <code>glassPane</code> fills the entire viewable |
|
149 |
* area of the <code>JRootPane</code> (bounds - insets). |
|
150 |
* <LI>The <code>layeredPane</code> fills the entire viewable area of the |
|
151 |
* <code>JRootPane</code>. (bounds - insets) |
|
152 |
* <LI>The <code>menuBar</code> is positioned at the upper edge of the |
|
153 |
* <code>layeredPane</code>. |
|
154 |
* <LI>The <code>contentPane</code> fills the entire viewable area, |
|
155 |
* minus the <code>menuBar</code>, if present. |
|
156 |
* </OL> |
|
157 |
* Any other views in the <code>JRootPane</code> view hierarchy are ignored. |
|
158 |
* <p> |
|
159 |
* If you replace the <code>LayoutManager</code> of the <code>JRootPane</code>, |
|
160 |
* you are responsible for managing all of these views. |
|
161 |
* So ordinarily you will want to be sure that you |
|
162 |
* change the layout manager for the <code>contentPane</code> rather than |
|
163 |
* for the <code>JRootPane</code> itself! |
|
164 |
* <p> |
|
165 |
* The painting architecture of Swing requires an opaque |
|
166 |
* <code>JComponent</code> |
|
21278 | 167 |
* to exist in the containment hierarchy above all other components. This is |
2 | 168 |
* typically provided by way of the content pane. If you replace the content |
169 |
* pane, it is recommended that you make the content pane opaque |
|
170 |
* by way of <code>setOpaque(true)</code>. Additionally, if the content pane |
|
171 |
* overrides <code>paintComponent</code>, it |
|
172 |
* will need to completely fill in the background in an opaque color in |
|
173 |
* <code>paintComponent</code>. |
|
174 |
* <p> |
|
175 |
* <strong>Warning:</strong> Swing is not thread safe. For more |
|

181 |
* Serialized objects of this class will not be compatible with |

|
183 |
* appropriate for short term storage or RMI between applications running |
|
184 |
* the same version of Swing. As of 1.4, support for long term storage |
|
20458 | 185 |
* of all JavaBeans™ |
