| 62 | * <code>JOptionPane</code> makes it easy to pop up a standard dialog box that |
| 63 | * prompts users for a value or informs them of something. |
| 64 | * For information about using <code>JOptionPane</code>, see |
| 65 | * <a |
| 66 | href="http://java.sun.com/docs/books/tutorial/uiswing/components/dialog.html">How to Make Dialogs</a>, |
| 67 | * a section in <em>The Java Tutorial</em>. |
| 68 | * |
| 69 | * <p> |
| 70 | * |
| 71 | * While the <code>JOptionPane</code> |
| 72 | * class may appear complex because of the large number of methods, almost |
| 73 | * all uses of this class are one-line calls to one of the static |
| 74 | * <code>showXxxDialog</code> methods shown below: |
| 75 | * <blockquote> |
| 76 | * |
| 77 | * |
| 78 | * <table border=1 summary="Common JOptionPane method names and their descriptions"> |
| 79 | * <tr> |
| 80 | * <th>Method Name</th> |
| 81 | * <th>Description</th> |
| 82 | * </tr> |
| 83 | * <tr> |
| 84 | * <td>showConfirmDialog</td> |
| 85 | * <td>Asks a confirming question, like yes/no/cancel.</td> |
| 86 | * </tr> |
| 87 | * <tr> |
| 88 | * <td>showInputDialog</td> |
| 89 | * <td>Prompt for some input.</td> |
| 90 | * </tr> |
| 91 | * <tr> |
| 92 | * <td>showMessageDialog</td> |
| 93 | * <td>Tell the user about something that has happened.</td> |
| 94 | * </tr> |
| 95 | * <tr> |
| 96 | * <td>showOptionDialog</td> |
| 97 | * <td>The Grand Unification of the above three.</td> |
| 98 | * </tr> |
| 99 | * </table> |
| 100 | * |
| 101 | * </blockquote> |
| 102 | * Each of these methods also comes in a <code>showInternalXXX</code> |
| 103 | * flavor, which uses an internal frame to hold the dialog box (see |
| 104 | * {@link JInternalFrame}). |
| 105 | * Multiple convenience methods have also been defined -- overloaded |
| 106 | * versions of the basic methods that use different parameter lists. |
| 107 | * <p> |
| 108 | * All dialogs are modal. Each <code>showXxxDialog</code> method blocks |
| 109 | * the caller until the user's interaction is complete. |
| 110 | * <p> |
| 111 | * |
| 112 | * <table cellspacing=6 cellpadding=4 border=0 align=right summary="layout"> |
| 113 | * <tr> |
| 114 | * <td bgcolor=#FFe0d0 rowspan=2>icon</td> |
| 115 | * <td bgcolor=#FFe0d0>message</td> |
| 116 | * </tr> |
| 117 | * <tr> |
| 118 | * <td bgcolor=#FFe0d0>input value</td> |
| 119 | * </tr> |
| 120 | * <tr> |
| 121 | * <td bgcolor=#FFe0d0 colspan=2>option buttons</td> |
| 122 | * </tr> |
| 123 | * </table> |
| 124 | * |
| 125 | * The basic appearance of one of these dialog boxes is generally |
| 126 | * similar to the picture at the right, although the various |
| 127 | * look-and-feels are |
| 128 | * ultimately responsible for the final result. In particular, the |
| 129 | * look-and-feels will adjust the layout to accommodate the option pane's |
| 130 | * <code>ComponentOrientation</code> property. |
| 131 | * <br clear=all> |
| 132 | * <p> |
| 133 | * <b>Parameters:</b><br> |
| 134 | * The parameters to these methods follow consistent patterns: |
| 135 | * <blockquote> |
| 136 | * <dl compact> |
| 137 | * <dt>parentComponent<dd> |
| 138 | * Defines the <code>Component</code> that is to be the parent of this |
| 139 | * dialog box. |
| 140 | * It is used in two ways: the <code>Frame</code> that contains |
| 141 | * it is used as the <code>Frame</code> |
| 142 | * parent for the dialog box, and its screen coordinates are used in |
| 143 | * the placement of the dialog box. In general, the dialog box is placed |
| 144 | * just below the component. This parameter may be <code>null</code>, |
| 145 | * in which case a default <code>Frame</code> is used as the parent, |
| 146 | * and the dialog will be |
| 147 | * centered on the screen (depending on the L&F). |
| 148 | * <dt><a name=message>message</a><dd> |
| 149 | * A descriptive message to be placed in the dialog box. |
| 150 | * In the most common usage, message is just a <code>String</code> or |
| 151 | * <code>String</code> constant. |
| 152 | * However, the type of this parameter is actually <code>Object</code>. Its |
| 153 | * interpretation depends on its type: |
| 154 | * <dl compact> |
| 155 | * <dt>Object[]<dd>An array of objects is interpreted as a series of |
| 156 | * messages (one per object) arranged in a vertical stack. |
| 157 | * The interpretation is recursive -- each object in the |
| 158 | * array is interpreted according to its type. |
| 159 | * <dt>Component<dd>The <code>Component</code> is displayed in the dialog. |
| 160 | * <dt>Icon<dd>The <code>Icon</code> is wrapped in a <code>JLabel</code> |
| 161 | * and displayed in the dialog. |
| 162 | * <dt>others<dd>The object is converted to a <code>String</code> by calling |
| 163 | * its <code>toString</code> method. The result is wrapped in a |
| 164 | * <code>JLabel</code> and displayed. |
| 165 | * </dl> |
| 166 | * <dt>messageType<dd>Defines the style of the message. The Look and Feel |
| 167 | * manager may lay out the dialog differently depending on this value, and |
| 168 | * will often provide a default icon. The possible values are: |
| 169 | * <ul> |
| 170 | * <li><code>ERROR_MESSAGE</code> |
| 171 | * <li><code>INFORMATION_MESSAGE</code> |
| 172 | * <li><code>WARNING_MESSAGE</code> |
| 173 | * <li><code>QUESTION_MESSAGE</code> |
| 174 | * <li><code>PLAIN_MESSAGE</code> |
| 175 | * </ul> |
| 176 | * <dt>optionType<dd>Defines the set of option buttons that appear at |
| 177 | * the bottom of the dialog box: |
| 178 | * <ul> |
| 179 | * <li><code>DEFAULT_OPTION</code> |
| 180 | * <li><code>YES_NO_OPTION</code> |
| 181 | * <li><code>YES_NO_CANCEL_OPTION</code> |
| 182 | * <li><code>OK_CANCEL_OPTION</code> |
| 183 | * </ul> |
| 184 | * You aren't limited to this set of option buttons. You can provide any |
| 185 | * buttons you want using the options parameter. |
| 186 | * <dt>options<dd>A more detailed description of the set of option buttons |
| 187 | * that will appear at the bottom of the dialog box. |
| 188 | * The usual value for the options parameter is an array of |
| 189 | * <code>String</code>s. But |
| 190 | * the parameter type is an array of <code>Objects</code>. |
| 191 | * A button is created for each object depending on its type: |
| 192 | * <dl compact> |
| 193 | * <dt>Component<dd>The component is added to the button row directly. |
| 194 | * <dt>Icon<dd>A <code>JButton</code> is created with this as its label. |
| 195 | * <dt>other<dd>The <code>Object</code> is converted to a string using its |
| 196 | * <code>toString</code> method and the result is used to |
| 197 | * label a <code>JButton</code>. |
| 198 | * </dl> |
| 199 | * <dt>icon<dd>A decorative icon to be placed in the dialog box. A default |
| 200 | * value for this is determined by the <code>messageType</code> parameter. |
| 201 | * <dt>title<dd>The title for the dialog box. |
| 202 | * <dt>initialValue<dd>The default selection (input value). |
| 203 | * </dl> |
| 204 | * </blockquote> |
| 205 | * <p> |
| 206 | * When the selection is changed, <code>setValue</code> is invoked, |
| 207 | * which generates a <code>PropertyChangeEvent</code>. |
| 208 | * <p> |
| 209 | * If a <code>JOptionPane</code> has configured to all input |
| 210 | * <code>setWantsInput</code> |
| 211 | * the bound property <code>JOptionPane.INPUT_VALUE_PROPERTY</code> |
| 212 | * can also be listened |
| 213 | * to, to determine when the user has input or selected a value. |
| 214 | * <p> |
| 215 | * When one of the <code>showXxxDialog</code> methods returns an integer, |
| 216 | * the possible values are: |
| 217 | * <ul> |
| 218 | * <li><code>YES_OPTION</code> |
| 219 | * <li><code>NO_OPTION</code> |
| 220 | * <li><code>CANCEL_OPTION</code> |
| 221 | * <li><code>OK_OPTION</code> |
| 222 | * <li><code>CLOSED_OPTION</code> |
| 223 | * </ul> |
| 224 | * <b>Examples:</b> |
| 225 | * <dl> |
| 226 | * <dt>Show an error dialog that displays the message, 'alert': |
| 227 | * <dd><code> |
| 228 | * JOptionPane.showMessageDialog(null, "alert", "alert", JOptionPane.ERROR_MESSAGE); |
| 229 | * </code><p> |
| 230 | * <dt>Show an internal information dialog with the message, 'information': |
| 231 | * <dd><code> |
| 232 | * JOptionPane.showInternalMessageDialog(frame, "information",<br> |
| 233 | * <ul><ul>"information", JOptionPane.INFORMATION_MESSAGE);</ul></ul> |
| 234 | * </code><p> |
| 235 | * <dt>Show an information panel with the options yes/no and message 'choose one': |
| 236 | * <dd><code>JOptionPane.showConfirmDialog(null, |
| 237 | * <ul><ul>"choose one", "choose one", JOptionPane.YES_NO_OPTION);</ul></ul> |
| 238 | * </code><p> |
| 239 | * <dt>Show an internal information dialog with the options yes/no/cancel and |
| 240 | * message 'please choose one' and title information: |
| 241 | * <dd><code>JOptionPane.showInternalConfirmDialog(frame, |
| 242 | * <ul><ul>"please choose one", "information",</ul></ul> |
| 243 | * <ul><ul>JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.INFORMATION_MESSAGE);</ul></ul> |
| 244 | * </code><p> |
| 245 | * <dt>Show a warning dialog with the options OK, CANCEL, title 'Warning', and |
| 246 | * message 'Click OK to continue': |
| 247 | * <dd><code> |
| 248 | * Object[] options = { "OK", "CANCEL" };<br> |
| 249 | * JOptionPane.showOptionDialog(null, "Click OK to continue", "Warning", |
| 250 | * <ul><ul>JOptionPane.DEFAULT_OPTION, JOptionPane.WARNING_MESSAGE,</ul></ul> |
| 251 | * <ul><ul>null, options, options[0]);</ul></ul> |
| 252 | * </code><p> |
| 253 | * <dt>Show a dialog asking the user to type in a String: |
| 254 | * <dd><code> |
| 255 | * String inputValue = JOptionPane.showInputDialog("Please input a value"); |
| 256 | * </code><p> |
| 257 | * <dt>Show a dialog asking the user to select a String: |
| 258 | * <dd><code> |
| 259 | * Object[] possibleValues = { "First", "Second", "Third" };<br> |
| 260 | * Object selectedValue = JOptionPane.showInputDialog(null, |
| 261 | * <ul><ul>"Choose one", "Input",</ul></ul> |
| 262 | * <ul><ul>JOptionPane.INFORMATION_MESSAGE, null,</ul></ul> |
| 263 | * <ul><ul>possibleValues, possibleValues[0]);</ul></ul> |
| 264 | * </code><p> |
| 265 | * </dl> |
| 266 | * <b>Direct Use:</b><br> |
| 267 | * To create and use an <code>JOptionPane</code> directly, the |
| 268 | * standard pattern is roughly as follows: |
| 269 | * <pre> |
| 270 | * JOptionPane pane = new JOptionPane(<i>arguments</i>); |
| 271 | * pane.set<i>.Xxxx(...); // Configure</i> |
| 272 | * JDialog dialog = pane.createDialog(<i>parentComponent, title</i>); |
| 273 | * dialog.show(); |
| 274 | * Object selectedValue = pane.getValue(); |
| 275 | * if(selectedValue == null) |
| 276 | * return CLOSED_OPTION; |
| 277 | * <i>//If there is <b>not</b> an array of option buttons:</i> |
| 278 | * if(options == null) { |
| 279 | * if(selectedValue instanceof Integer) |
| 280 | * return ((Integer)selectedValue).intValue(); |
| 281 | * return CLOSED_OPTION; |
| 282 | * } |
| 283 | * <i>//If there is an array of option buttons:</i> |
| 284 | * for(int counter = 0, maxCounter = options.length; |
| 285 | * counter < maxCounter; counter++) { |
| 286 | * if(options[counter].equals(selectedValue)) |
| 287 | * return counter; |
| 288 | * } |
| 289 | * return CLOSED_OPTION; |
| 290 | * </pre> |
