          public void setPickerIconWidth(java.lang.Integer pickerIconWidth)

      If `showPickerIcon` is true for this item, this property governs the size of the picker icon. If unset, the picker icon will be sized as a square to fit in the available height for the icon.

      It is not recommended to change the pickerIconWidth from the default value if `spriting` is enabled because the image sprites are set up assuming specific, fixed dimensions of the picker icon. If the pickerIconWidth must be changed, then the `pickerIconStyle` should be changed to a custom CSS style name.

      Overrides:

      Overrides:
        `setShowPickerIcon` in class `FormItem`
      Parameters:
        `showPickerIcon` - Default value is true

    - #### getShowPickerIcon

          public java.lang.Boolean getShowPickerIcon()

      Should the pick button icon be shown for choosing colors from a ColorPicker
      Overrides:
        `getShowPickerIcon` in class `FormItem`
      Returns:
        Boolean

    - #### setSupportsTransparency

          public void setSupportsTransparency(java.lang.Boolean supportsTransparency)

      Determines whether the `ColorPicker` associated with this ColorItem allows the user to set transparency/opacity information whilst selecting a color. If false, no opacity slider is shown and all colors are 100% opaque.

      Note ColorItems are representations of HTML color strings, they do not implicitly support transparency. Setting supportsTransparency to true just allows the user to set opacity with the picker; if you actually want to capture that information, you will also need to override `ColorItem.pickerColorSelected()`.

      Parameters:
        `supportsTransparency` - Default value is false

    - #### getSupportsTransparency

          public java.lang.Boolean getSupportsTransparency()

      Determines whether the `ColorPicker` associated with this ColorItem allows the user to set transparency/opacity information whilst selecting a color. If false, no opacity slider is shown and all colors are 100% opaque.

      Note ColorItems are representations of HTML color strings, they do not implicitly support transparency. Setting supportsTransparency to true just allows the user to set opacity with the picker; if you actually want to capture that information, you will also need to override `ColorItem.pickerColorSelected()`.

      Returns:
        Boolean

    - #### addPickerColorSelectedHandler

          public com.google.gwt.event.shared.HandlerRegistration addPickerColorSelectedHandler(PickerColorSelectedHandler handler)

      Add a pickerColorSelected handler.

      Store the color value selected by the user from the color picker. You will need to override this method if you wish to capture opacity information from the `ColorPicker`

      Specified by:
        `addPickerColorSelectedHandler` in interface `HasPickerColorSelectedHandlers`
      Parameters:
        `handler` - the pickerColorSelected handler
      Returns:
        `HandlerRegistration` used to remove this handler

    - #### setDefaultProperties

          public static void setDefaultProperties(ColorItem colorItemProperties)

      Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

      Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

      Parameters:
        `colorItemProperties` - properties that should be used as new defaults when instances of this class are created
