The JColorChooser Class

The JColorChooser class allows you to create a standard dialog with a color palette from which users can select a color.

Properties

In addition to the typical UI properties of Swing components, the color chooser has the properties listed in Table 12-6. The chooserPanels property contains an array of all the chooser panels currently associated with this color chooser. You can get and set the entire array at once or, more commonly, you can add and remove chooser panels using some of the methods described later. The color property contains the currently selected color in the chooser. (This property is just a convenient access point for the selectedColor property of the selectionModel.) The previewPanel property contains the JComponent subclass that previews your color choice. (You can see an example of the default preview panel in Figure 12-7.) The selectionModel property dictates which selection model the chooser uses. The dragEnabled property allows you to drag colors from the chooser to another part of your application, but no transferHandler (inherited from JPanel) is in place to support this feature yet. You would need to supply a handler to make this property meaningful.
