Class ColorChooserBox

  • All Implemented Interfaces:
    EventHandler, PenListener
    public class ColorChooserBox
extends Window
implements PenListener
    Shows a color dialog that can be used to select a color. There are several ways to choose a color:
    • Using a color matrix
    • Using a websafe palette
    • Writting the red, green and blue components
    • Writting the color in hexdecimal.
    Here's a sample code: 
     ColorChooserBox ccb = new ColorChooserBox(getBackColor());
 ccb.popup();
 if (ccb.choosenColor != -1) // user pressed cancel?
 {
    int color = ccb.choosenColor; // no, color was selected
 }
