The widget appears as a button which contains a "color swatch" of the
currently selected color. When the button is pressed, the widget
presents the user with a color selection dialog where the color can be
selected. </P

>You can select the color to be displayed in a number of ways:
floating point values for the red, green and blue channels,
integers in the range 0 to 65,535, or integers in the range 0 to 255,
depending on your needs.</P
