A color chooser provides one or more content panes from which users can select colors and a preview mechanism by which users can view the selected colors in context. You can display a color chooser in a dialog box, as shown in the following figure. The three command buttons (OK, Cancel, and Help) are part of the dialog box, not the color chooser. (A color chooser can also be implemented in a multiple-use dialog box.)Figure 120 JFC-Supplied Color Chooser
If your application requires a different method for choosing colors, you can add a content pane with that feature. You can also remove existing content panes. If you use only one content pane, the tabs disappear. In addition, you can specify your own preview panel or alter the supplied one.
The color chooser is a panel. The color panel can be inserted in a dialog box by using the
JDialog container. This operation is accomplished with the static method
CreateDialog on the
JColorChooser container. Alternately, this can be done with the
ShowDialog method, which creates, displays, and dismisses the dialog box.
