/*C+ NumericInput
*
*    DESCRIPTION:
*
*    A NumericInput object displays text and allows the user to enter any
*    number of numeric characters (integer value).  The user may click
*    on increment and decrement arrows to change the integer value.
*
*    INHERITED CLASSES:
*
*    UIInputTextItem - All input text items, numeric or Numeric,
*                      inherit this.  UIInputTextItem is used to
*                      provide a foundationof functionality specific
*                      to input text items.
*
*    ORDINARY DATA MEMBERS:
*
*    int     value;	  - The initial value of item.
*    Boolean valueSet;    - Specifies an initial value has been set.
*    int     minValue;    - The minimum value of the item.
*    Boolean minValueSet; - Specifies that a minimum value has been set.
*    int     maxValue;    - The maximum value of the item.
*    Boolean maxValueSet; - Specifies that a maximum value has been set.
*
*    PUBLIC MEMBER FUNCTIONS:
*
*    int   getValue (int&)
*          - Gets the value of the numeric field of the Numeric object.
*    void  setValue (int)
*          - Sets the value of the numeric field of the Numeric object.
*            Default: XView default.
*
*    void  setMinValue (int min)
*    void  setMaxValue (int max)
*    void  setMinAndMaxValues (int min, int max)
*          - Allows setting of the minimum and/or maximum values allowed by the
*            Numeric object.  Default: XView defaults.
*
*    PROTECTED MEMBER FUNCTIONS:
*
*    virtual void createObject (UIObject *)
*          - Creates the XView object.
*
*    PRIVATE MEMBER FUNCTIONS:
*
*    void setNumericInputDefaults ()
*         - Initializes data members.
