| 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}. | ||
