* A component that displays a list of objects and allows the user to select |
|
57 |
* one or more items. A separate model, {@code ListModel}, maintains the |
|
58 |
* contents of the list. |
|
59 |
* <p> |
|
60 |
* It's easy to display an array or Vector of objects, using the {@code JList} |
|
61 |
* constructor that automatically builds a read-only {@code ListModel} instance |
|
62 |
* for you: |
|
63 |
* <pre> |
|
4378 | 64 |
* {@code |
2 | 65 |
* // Create a JList that displays strings from an array |
66 |
* |
|
67 |
* String[] data = {"one", "two", "three", "four"}; |
|
4378 | 68 |
* JList<String> myList = new JList<String>(data); |
2 | 69 |
* |
70 |
* // Create a JList that displays the superclasses of JList.class, by |
|
71 |
* // creating it with a Vector populated with this data |
|
72 |
* |
|
4378 | 73 |
* Vector<Class<?>> superClasses = new Vector<Class<?>>(); |
74 |
* Class<JList> rootClass = javax.swing.JList.class; |
|
75 |
* for(Class<?> cls = rootClass; cls != null; cls = cls.getSuperclass()) { |
|
2 | 76 |
* superClasses.addElement(cls); |
77 |
* } |
|
4378 | 78 |
* JList<Class<?>> myList = new JList<Class<?>>(superClasses); |
2 | 79 |
* |
80 |
* // The automatically created model is stored in JList's "model" |
|
81 |
* // property, which you can retrieve |
|
82 |
* |
|
4378 | 83 |
* ListModel<Class<?>> model = myList.getModel(); |
2 | 84 |
* for(int i = 0; i < model.getSize(); i++) { |
85 |
* System.out.println(model.getElementAt(i)); |
|
86 |
* } |
|
4378 | 87 |
* } |
2 | 88 |
* </pre> |
89 |
* <p> |
|
90 |
* A {@code ListModel} can be supplied directly to a {@code JList} by way of a |
|
91 |
* constructor or the {@code setModel} method. The contents need not be static - |
|
92 |
* the number of items, and the values of items can change over time. A correct |
|
93 |
* {@code ListModel} implementation notifies the set of |
|
94 |
* {@code javax.swing.event.ListDataListener}s that have been added to it, each |
|
95 |
* time a change occurs. These changes are characterized by a |
|
96 |
* {@code javax.swing.event.ListDataEvent}, which identifies the range of list |
|
97 |
* indices that have been modified, added, or removed. {@code JList}'s |
|
98 |
* {@code ListUI} is responsible for keeping the visual representation up to |
|
99 |
* date with changes, by listening to the model. |
|
100 |
* <p> |
|
101 |
* Simple, dynamic-content, {@code JList} applications can use the |
|
102 |
* {@code DefaultListModel} class to maintain list elements. This class |
|
103 |
* implements the {@code ListModel} interface and also provides a |
|
104 |
* <code>java.util.Vector</code>-like API. Applications that need a more |
|
105 |
* custom <code>ListModel</code> implementation may instead wish to subclass |
|
106 |
* {@code AbstractListModel}, which provides basic support for managing and |
|
107 |
* notifying listeners. For example, a read-only implementation of |
|
108 |
* {@code AbstractListModel}: |
|
109 |
* <pre> |
|
4378 | 110 |
* {@code |
2 | 111 |
* // This list model has about 2^16 elements. Enjoy scrolling. |
112 |
* |
|
4378 | 113 |
* ListModel<String> bigData = new AbstractListModel<String>() { |
2 | 114 |
* public int getSize() { return Short.MAX_VALUE; } |
4378 | 115 |
* public String getElementAt(int index) { return "Index " + index; } |
2 | 116 |
* }; |
4378 | 117 |
* } |
2 | 118 |
* </pre> |
119 |
* <p> |
|
120 |
* The selection state of a {@code JList} is managed by another separate |
|
121 |
* model, an instance of {@code ListSelectionModel}. {@code JList} is |
|
122 |
* initialized with a selection model on construction, and also contains |
|
123 |
* methods to query or set this selection model. Additionally, {@code JList} |
|
124 |
* provides convenient methods for easily managing the selection. These methods, |
|
125 |
* such as {@code setSelectedIndex} and {@code getSelectedValue}, are cover |
|
126 |
* methods that take care of the details of interacting with the selection |
|
127 |
* model. By default, {@code JList}'s selection model is configured to allow any |
|
128 |
* combination of items to be selected at a time; selection mode |
|
129 |
* {@code MULTIPLE_INTERVAL_SELECTION}. The selection mode can be changed |
|
130 |
* on the selection model directly, or via {@code JList}'s cover method. |
|
131 |
* Responsibility for updating the selection model in response to user gestures |
|
132 |
* lies with the list's {@code ListUI}. |
|
133 |
* <p> |
|
134 |
* A correct {@code ListSelectionModel} implementation notifies the set of |
|
135 |
* {@code javax.swing.event.ListSelectionListener}s that have been added to it |
|
136 |
* each time a change to the selection occurs. These changes are characterized |
|
137 |
* by a {@code javax.swing.event.ListSelectionEvent}, which identifies the range |
|
138 |
* of the selection change. |
|
139 |
* <p> |
|
140 |
* The preferred way to listen for changes in list selection is to add |
|
141 |
* {@code ListSelectionListener}s directly to the {@code JList}. {@code JList} |

2 | 149 |
* Painting of cells in a {@code JList} is handled by a delegate called a |
150 |
* cell renderer, installed on the list as the {@code cellRenderer} property. |
|
151 |
* The renderer provides a {@code java.awt.Component} that is used |
|
152 |
* like a "rubber stamp" to paint the cells. Each time a cell needs to be |
|
153 |
* painted, the list's {@code ListUI} asks the cell renderer for the component, |
|
154 |
* moves it into place, and has it paint the contents of the cell by way of its |
|
155 |
* {@code paint} method. A default cell renderer, which uses a {@code JLabel} |
|
156 |
* component to render, is installed by the lists's {@code ListUI}. You can |
|
157 |
* substitute your own renderer using code like this: |
|
158 |
* <pre> |
|
4378 | 159 |
* {@code |
2 | 160 |
* // Display an icon and a string for each object in the list. |

4378 | 194 |
* } |
2 | 195 |
* </pre> |
196 |
* <p> |
|
197 |
* Another job for the cell renderer is in helping to determine sizing |
|
198 |
* information for the list. By default, the list's {@code ListUI} determines |
|
199 |
* the size of cells by asking the cell renderer for its preferred |
|
200 |
* size for each list item. This can be expensive for large lists of items. |
|
201 |
* To avoid these calculations, you can set a {@code fixedCellWidth} and |
|
202 |
* {@code fixedCellHeight} on the list, or have these values calculated |
|
203 |
* automatically based on a single prototype value: |
|
21592 | 204 |
* <a name="prototype_example"></a> |
2 | 205 |
* <pre> |
4378 | 206 |
* {@code |
207 |
* JList<String> bigDataList = new JList<String>(bigData); |
|
2 | 208 |
* |
209 |
* // We don't want the JList implementation to compute the width |
|
210 |
* // or height of all of the list cells, so we give it a string |
|
211 |
* // that's as big as we'll need for any cell. It uses this to |
|
212 |
* // compute values for the fixedCellWidth and fixedCellHeight |
|
213 |
* // properties. |
|
214 |
* |
|
215 |
* bigDataList.setPrototypeCellValue("Index 1234567890"); |
|
4378 | 216 |
* } |
2 | 217 |
* </pre> |
218 |
* <p> |
|
219 |
* {@code JList} doesn't implement scrolling directly. To create a list that |
|
220 |
* scrolls, make it the viewport view of a {@code JScrollPane}. For example: |
|
221 |
* <pre> |
|
222 |
* JScrollPane scrollPane = new JScrollPane(myList); |
|
223 |
* |
|
224 |
* // Or in two steps: |
|
225 |
* JScrollPane scrollPane = new JScrollPane(); |
|
226 |
* scrollPane.getViewport().setView(myList); |
|
227 |
* </pre> |
|
228 |
* <p> |
|
229 |
* {@code JList} doesn't provide any special handling of double or triple |
|
230 |
* (or N) mouse clicks, but it's easy to add a {@code MouseListener} if you |
|
231 |
* wish to take action on these events. Use the {@code locationToIndex} |
|
232 |
* method to determine what cell was clicked. For example: |
|
233 |
* <pre> |
|
234 |
* MouseListener mouseListener = new MouseAdapter() { |
|
235 |
* public void mouseClicked(MouseEvent e) { |
|
236 |
* if (e.getClickCount() == 2) { |
|
237 |
* int index = list.locationToIndex(e.getPoint()); |
|
238 |
* System.out.println("Double clicked on Item " + index); |
|
239 |
* } |
|
240 |
* } |
|
241 |
* }; |
|
242 |
* list.addMouseListener(mouseListener); |
|

* </pre> |

* Called to set or clear the drop location during a DnD operation. |
|
1341 |
* In some cases, the component may need to use it's internal selection |
|
1342 |
* temporarily to indicate the drop location. To help facilitate this, |
|
1343 |
* this method returns and accepts as a parameter a state object. |
|
1344 |
* This state object can be used to store, and later restore, the selection |
|
1345 |
* state. Whatever this method returns will be passed back to it in |
|
1346 |
* future calls, as the state parameter. If it wants the DnD system to |
|
1347 |
* continue storing the same state, it must pass it back every time. |
|
1348 |
* Here's how this is used: |
|
1349 |
* <p> |
|
1350 |
* Let's say that on the first call to this method the component decides |
|
1351 |
* to save some state (because it is about to use the selection to show |
|
1352 |
* a drop index). It can return a state object to the caller encapsulating |
|
1353 |
* any saved selection state. On a second call, let's say the drop location |
|
1354 |
* is being changed to something else. The component doesn't need to |
|
1355 |
* restore anything yet, so it simply passes back the same state object |
|
1356 |
* to have the DnD system continue storing it. Finally, let's say this |
|
1357 |
* method is messaged with <code>null</code>. This means DnD |
|
1358 |
* is finished with this component for now, meaning it should restore |
|
1359 |
* state. At this point, it can use the state parameter to restore |
|
1360 |
* said state, and of course return <code>null</code> since there's |
|
1361 |
* no longer anything to store. |
|
1362 |
* |
|
1363 |
* @param location the drop location (as calculated by |
|
1364 |
* <code>dropLocationForPoint</code>) or <code>null</code> |
|
1365 |
* if there's no longer a valid drop location |
|
1366 |
* @param state the state object saved earlier for this component, |
|
1367 |
* or <code>null</code> |
|
1368 |
* @param forDrop whether or not the method is being called because an |
