F.3. Building a ColorChooser
We now present a ColorChooser application to demonstrate the GroupLayout layout manager. The application consists of three JSlider objects, each representing the values from 0 to 255 for specifying the red, green and blue values of a color. The selected values for each JSlider will be used to display a filled rectangle of the specified color. We build the application using Netbeans 5.5. For an more detailed introduction to developing GUI applications in the NetBeans IDE, see www.netbeans.org/kb/trails/matisse.html.
