The currency field control com.sun.star.awt.UnoControlCurrencyField can be considered a specialization of the com.sun.star.awt.UnoControlNumericField. It is used for entering and displaying currency values. In addition to the currency value, reflected by the property Value, a currency symbol, set by the CurrencySymbol property, is displayed. If the PrependCurrencySymbol property is set to true, the currency symbol is displayed in front of the currency value.

  XTextComponent xTextComponent = null;
  try{
      // create a unique name by means of an own implementation...
      String sName = createUniqueName(m_xDlgModelNameContainer, "CurrencyField");
 
      // create a controlmodel at the multiservicefactory of the dialog model... 
      Object oCFModel = m_xMSFDialogModel.createInstance("com.sun.star.awt.UnoControlCurrencyFieldModel");

      // Set the properties at the model - keep in mind to pass the property names in alphabetical order! 
      xCFModelMPSet.setPropertyValues(
      new String[] {"Height", "Name", "PositionX", "PositionY", "Width"},
      new Object[] { new Integer(12), sName, new Integer(_nPositionX), new Integer(_nPositionY), new Integer(_nWidth)});
