===============
.. 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: `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, text, argFlags=0)
Converts text into `Variant` value appropriate for this property.
: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: `tuple`
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:
( `bool`, `variant` )
.. 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:`~wx.propgrid.PGProperty.GenerateComposedValue` .

See :meth:`~wx.propgrid.DateProperty.GetDatePickerStyle`
