Example 1
@Override
public int[] getValue(ColorSwtParameter p) {
	String key = p.getParamID();
	Color existing;

	boolean is_override = COConfigurationManager.getStringParameter(
			key).length() > 0;
	if (!is_override) {
		return getDefaultValue(p);
	}

	// getSchemedColor will return white when it can't find a key starting with "config."
	// but we just checked that above, so we are ok
	existing = ColorCache.getSchemedColor(display, key);

	return existing == null ? null : new int[] {
		existing.getRed(),
		existing.getGreen(),
		existing.getBlue()
	};
