// TextBox utility class
 
//
// This class is part of the Open Inventor Medical utility library.
//
// The medical utility classes are provided as a prebuilt library named
// "fei_inventor_medical", that can be used directly in an Open Inventor
// application. The classes in the prebuilt library are documented and
// supported by Thermo Fisher Scientific. These classes are also provided as source code.
//
// Please see $OIVHOME/include/Medical/InventorMedical.h for the full text.
