   **Possible constructors**::

       PropertyGridEvent(commandType=0, id=0)
       
       PropertyGridEvent(event)
       
   
   A property grid event holds information about events associated with
   PropertyGrid objects.

   .. method:: CanVeto(self)

      Returns ``True`` if you can veto the action that the event is signaling.                  

      :rtype: `bool`








   .. method:: GetColumn(self)

      Returns the column index associated with this event.                  

      For the column dragging events, it is the column to the left of the splitter being dragged                  

      :rtype: `int`








   .. method:: GetMainParent(self)

      Returns highest level non-category, non-root parent of property for which event occurred.                  

      Useful when you have nested properties with children. 

                

      :rtype: :ref:`wx.propgrid.PGProperty`







      .. note:: 

         If immediate parent is root or category, this will return the property itself.   








   .. method:: GetProperty(self)

      Returns property associated with this event.                  

                

      :rtype: :ref:`wx.propgrid.PGProperty`







      .. note:: 

         You should assume that this property can always be ``None``. For instance,  ``wxEVT_PG_SELECTED``   is emitted not only when a new property is selected, but also when selection is cleared by user activity.    








   .. method:: GetPropertyName(self)

      Returns name of the associated property.                  

                

      :rtype: `string`







      .. note:: 

         Property name is stored in event, so it remains accessible even after the associated property or the property grid has been deleted.   








   .. method:: GetPropertyValue(self)

      Returns value of the associated property.                  

      Works for all event types, but for  ``wxEVT_PG_CHANGING``   this member function returns the value that is pending, so you can call  :meth:`Veto`   if the value is not satisfactory. 

                

      :rtype: :ref:`PGVariant`







      .. note:: 

         Property value is stored in event, so it remains accessible even after the associated property or the property grid has been deleted.   







      .. seealso:: :meth:`GetPropertyValue`     








   .. method:: GetValidationFailureBehavior(self)

      Returns current validation failure flags.                  

      :rtype: :ref:`wx.propgrid.PGVFBFlags`








   .. method:: SetCanVeto(self, canVeto)

      Set if event can be vetoed.                  


      :param `canVeto`: 
      :type `canVeto`: bool







   .. method:: SetProperty(self, p)

      Changes the property associated with this event.                  


      :param `p`: 
      :type `p`: wx.propgrid.PGProperty







   .. method:: SetValidationFailureBehavior(self, flags)

      Set override validation failure behaviour.                  

      Only effective if :meth:`Veto`   was also called, and only allowed if event type is  ``wxEVT_PG_CHANGING`` .                   


      :param `flags`: 
      :type `flags`: wx.propgrid.PGVFBFlags







   .. method:: SetValidationFailureMessage(self, message)

      Sets custom failure message for this time only.                  

      Only applies if ``wx.propgrid.PG_VFB_SHOW_MESSAGE`` is set in validation failure flags.                  


      :param `message`: 
      :type `message`: string







   .. method:: Veto(self, veto=True)

      Call this from your event handler to veto action that the event is signaling.                  

      You can only veto a shutdown if :meth:`wx.propgrid.PropertyGridEvent.CanVeto`   returns ``True``. 

                


      :param `veto`: 
      :type `veto`: bool






      .. note:: 

         Currently only  ``wxEVT_PG_CHANGING``   supports vetoing.    








   .. method:: WasVetoed(self)

      Returns ``True`` if event was vetoed.                  

      :rtype: `bool`
