The date field control com.sun.star.awt.UnoControlDateField extends the text field control and is used for displaying and entering dates. The model is described in com.sun.star.awt.UnoControlDateFieldModel:

Properties of com.sun.star.awt.UnoControlDateFieldModel
Date	long. The date value displayed in the control. The type of the property is long and specified by the number format YYYYMMDD, where YYYY denotes fully qualified years, MM months, and DD days.
DateFormat	short. The DateFormat is a key that determines the number format of the displayed date.
DateMax	long. The maximum date that the user can enter
DateMin	long. The minimum date that the user can enter
DateShowCentury	This property is deprecated and should not be used.
Dropdown	boolean. The Dropdown property enables a calendar that the user can drop down to select a date.
Spin	boolean. The Spin property defines whether the control displays a spin button. This method reduces scrolling and selecting, to a one-step process.
StrictFormat	boolean. If set to true, only the allowed characters as specified by the DateFormat property are accepted. All other entries typed with the keyboard are ignored.

  public XPropertySet insertDateField(XSpinListener _xSpinListener, int _nPosX, int _nPosY, int _nWidth){
  XPropertySet xDFModelPSet = null;
  try{
      // create a unique name by means of an own implementation...
      String sName = createUniqueName(m_xDlgModelNameContainer, "DateField");
 
      // create a controlmodel at the multiservicefactory of the dialog model... 
      Object oDFModel = m_xMSFDialogModel.createInstance("com.sun.star.awt.UnoControlDateFieldModel");
      XMultiPropertySet xDFModelMPSet = (XMultiPropertySet) UnoRuntime.queryInterface(XMultiPropertySet.class, oDFModel);
 
      // Set the properties at the model - keep in mind to pass the property names in alphabetical order! 
      xDFModelMPSet.setPropertyValues(
      new String[] {"Dropdown", "Height", "Name", "PositionX", "PositionY", "Width"},
      new Object[] {Boolean.TRUE, new Integer(12), sName, new Integer(_nPosX), new Integer(_nPosY), new Integer(_nWidth)});
 
      // The controlmodel is not really available until inserted to the Dialog container 
      m_xDlgModelNameContainer.insertByName(sName, oDFModel);
      xDFModelPSet = (XPropertySet) UnoRuntime.queryInterface(XPropertySet.class, oDFModel);
 
      // The following properties may also be set with XMultiPropertySet but we
      // use the XPropertySet interface merely for reasons of demonstration 
      xDFModelPSet.setPropertyValue("DateFormat", new Short((short) 7));
      xDFModelPSet.setPropertyValue("DateMin", new Integer(20070401));
      xDFModelPSet.setPropertyValue("DateMax", new Integer(20070501));
      xDFModelPSet.setPropertyValue("Date", new Integer(20000415)); 
      Object oDFControl = m_xDlgContainer.getControl(sName);
 
      // add a SpinListener that is notified on each change of the controlvalue... 
      XSpinField xSpinField = (XSpinField) UnoRuntime.queryInterface(XSpinField.class, oDFControl);
      xSpinField.addSpinListener(_xSpinListener);
  }catch (com.sun.star.uno.Exception ex){
      /* perform individual exception handling here.
       * Possible exception types are:
       * com.sun.star.lang.IllegalArgumentException,
       * com.sun.star.lang.WrappedTargetException,

       * com.sun.star.beans.PropertyVetoException,
       * com.sun.star.beans.UnknownPropertyException,
       * com.sun.star.uno.Exception
       */
      ex.printStackTrace(System.out);
  }
      return xDFModelPSet;
  }

Although the date field control provides a spin button, there is no Step property. In this control, the interval steps of the spin button are set automatically and depend on the position of the cursor within the date display. This means that if, for example, the cursor is within the month section of the date display, only the months are controlled by the spin button.
