| 40 | +/** | |
| 41 | + * <code>JColorChooser</code> provides a pane of controls designed to allow | |
| 42 | + * a user to manipulate and select a color. | |
| 43 | + * For information about using color choosers, see | |
| 44 | + * <a | |
| 45 | + href="http://java.sun.com/docs/books/tutorial/uiswing/components/colorchooser.html">How to Use Color Choosers</a>, | |
| 46 | + * a section in <em>The Java Tutorial</em>. | |
| 47 | + * | |
| 48 | + * <p> | |
| 49 | + * | |
| 50 | + * This class provides three levels of API: | |
| 51 | + * <ol> | |
| 52 | + * <li>A static convenience method which shows a modal color-chooser | |
| 53 | + * dialog and returns the color selected by the user. | |
| 54 | + * <li>A static convenience method for creating a color-chooser dialog | |
| 55 | + * where <code>ActionListeners</code> can be specified to be invoked when | |
| 56 | + * the user presses one of the dialog buttons. | |
| 57 | + * <li>The ability to create instances of <code>JColorChooser</code> panes | |
| 58 | + * directly (within any container). <code>PropertyChange</code> listeners | |
| 59 | + * can be added to detect when the current "color" property changes. | |
| 60 | + * </ol> | |
| 61 | + * <p> | |
| 62 | + * <strong>Warning:</strong> Swing is not thread safe. For more | |
| 63 | + * information see <a | |
| 64 | + * href="package-summary.html#threading">Swing's Threading | |
| 65 | + * Policy</a>. | |
| 66 | + * <p> | |
| 67 | + * <strong>Warning:</strong> | |
| 68 | + * Serialized objects of this class will not be compatible with | |
| 69 | + * future Swing releases. The current serialization support is | |
| 70 | + * appropriate for short term storage or RMI between applications running | |
| 71 | + * the same version of Swing. As of 1.4, support for long term storage | |
| 72 | + * of all JavaBeans<sup><font size="-2">TM</font></sup> | |
| 73 | + * has been added to the <code>java.beans</code> package. | |
| 74 | + * Please see {@link java.beans.XMLEncoder}. | |
