|phoenix_title|  **wx.propgrid.DateProperty**
==========================================================================================================================================

Property representing :ref:`wx.DateTime`.          

**Supported special attributes:**

- "DateFormat": Determines displayed date format. 
- "PickerStyle": Determines window style used with :ref:`wx.adv.DatePickerCtrl`. Default is ``wx.adv.DP_DEFAULT`` | ``wx.adv.DP_SHOWCENTURY``. Using ``wx.adv.DP_ALLOWNONE`` enables additional support for unspecified property value.

===============


.. class:: wx.propgrid.DateProperty(PGProperty)

   **Possible constructors**::

       DateProperty(label=PG_LABEL, name=PG_LABEL, value=DateTime())
       
   
   Property representing DateTime.



   .. method:: __init__(self, label=PG_LABEL, name=PG_LABEL, value=DateTime())




      :param `label`: 
      :type `label`: string
      :param `name`: 
      :type `name`: string
      :param `value`: 
      :type `value`: wx.DateTime







   .. method:: DoSetAttribute(self, name, value)

      Reimplement this member function to add special handling for attributes of this property.                  

                


      :param `name`: 
      :type `name`: string
      :param `value`: 
      :type `value`: PGVariant




      :rtype: `bool`







      :returns: 

         Return ``False`` to have the attribute automatically stored in m_attributes. Default implementation simply does that and nothing else.  







      .. note:: 

         To actually set property attribute values from the application, use :meth:`wx.propgrid.PGProperty.SetAttribute`   instead.   








   .. method:: GetDatePickerStyle(self)



      :rtype: `long`








   .. method:: GetDateValue(self)



      :rtype: :ref:`DateTime`








   .. method:: GetFormat(self)



      :rtype: `string`








   .. method:: OnSetValue(self)

      This virtual function is called after m_value has been set.                  

                 



      .. note:: 

   

         - If m_value was set to Null variant (ie. unspecified value), :meth:`OnSetValue`   will not be called. 
         - m_value may be of any variant type. Typically properties internally support only one variant type, and as such :meth:`OnSetValue`   provides a good opportunity to convert supported values into internal type. 
         - Default implementation does nothing.  











   .. method:: SetDateValue(self, dt)




      :param `dt`: 
      :type `dt`: wx.DateTime







   .. method:: SetFormat(self, format)




      :param `format`: 
      :type `format`: string







   .. method:: StringToValue(self, variant, text, argFlags=0)

      Converts text into :ref:`Variant`  value appropriate for this property.                  




      :param `variant`: On function entry this is the old value (should not be NullVariant in normal cases). Translated value must be assigned back to it.  
      :type `variant`: PGVariant
      :param `text`: Text to be translated into variant.  
      :type `text`: string
      :param `argFlags`: If ``wx.propgrid.PG_FULL_VALUE`` is set, returns complete, storable value instead of displayable one (they may be different). If ``wx.propgrid.PG_COMPOSITE_FRAGMENT`` is set, text is interpreted as a part of composite property string value (as generated by :meth:`ValueToString`   called with this same flag).  
      :type `argFlags`: int










      :rtype: `bool`




      You might want to take into account that m_value is Null variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).                    



      :returns: 

         Returns ``True`` if resulting :ref:`Variant`  value was different.  







      .. note:: 

         Default implementation converts semicolon delimited tokens into child values. Only works for properties with children.  








   .. method:: ValueToString(self, value, argFlags=0)

      Converts property value into a text representation.                  




      :param `value`: Value to be converted.   
      :type `value`: PGVariant
      :param `argFlags`: If 0 (default value), then displayed string is returned. If ``wx.propgrid.PG_FULL_VALUE`` is set, returns complete, storable string value instead of displayable. If ``wx.propgrid.PG_EDITABLE_VALUE`` is set, returns string value that must be editable in textctrl. If ``wx.propgrid.PG_COMPOSITE_FRAGMENT`` is set, returns text that is appropriate to display as a part of string property's composite text representation.  
      :type `argFlags`: int








      :rtype: `string`



                  



      .. note:: 

         Default implementation calls :meth:`GenerateComposedValue` .
