    - #### setDefaultProperties

          public static void setDefaultProperties(CheckboxItem checkboxItemProperties)

      Class level method to set the default properties of this class. If set, then all subsequent instances of this class will automatically have the default properties that were set when this method was called. 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 effect 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.

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

    - #### setShowUnsetImage

          public void setShowUnsetImage(java.lang.Boolean showUnsetImage)

      Determines what image to display when the value for this checkbox is unset. Set to true to display the `unsetImage` for null values, or false to use the `uncheckedImage` for both null and explicitly unchecked values.

      If this attribute is not set, the `unsetImage` for null values if `allowEmptyValue` is true for this item, otherwise the unchecked image will be used.

      Parameters:
