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

   **Possible constructors**::

       FontProperty(label=PG_LABEL, name=PG_LABEL, value=Font())
       
   
   Property representing Font.



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




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







   .. method:: ChildChanged(self, thisValue, childIndex, childValue)

      Called after value of a child property has been altered.                  

      Must return new value of the whole property (after any alterations warranted by child's new value). 

      Note that this function is usually called at the time that value of this property, or given child property, is still pending for change, and as such, result of :meth:`GetValue`   or m_value should not be relied on. 

      Sample pseudo-code implementation: 

      ::

          # TBW






      :param `thisValue`: Value of this property. Changed value should be returned (in previous versions of :ref:`wx.propgrid.PropertyGrid`  it was only necessary to write value back to this argument).   
      :type `thisValue`: PGVariant
      :param `childIndex`: Index of child changed (you can use Item(childIndex) to get child property).   
      :type `childIndex`: int
      :param `childValue`: (Pending) value of the child property.  
      :type `childValue`: PGVariant










      :rtype: :ref:`PGVariant`



                  



      :returns: 

         Modified value of the whole property.   








   .. method:: OnEvent(self, propgrid, wnd_primary, event)

      Events received by editor widgets are processed here.                  

      Note that editor class usually processes most events. Some, such as button press events of TextCtrlAndButton class, can be handled here. Also, if custom handling for regular events is desired, then that can also be done (for example, :ref:`wx.propgrid.SystemColourProperty`  custom handles  ``wxEVT_CHOICE``   to display colour picker dialog when 'custom' selection is made). 

      If the event causes value to be changed, :meth:`SetValueInEvent`   should be called to set the new value. 

      The parameter `event`  is the associated :ref:`wx.Event`. 




      :param `propgrid`: 
      :type `propgrid`: wx.propgrid.PropertyGrid
      :param `wnd_primary`: 
      :type `wnd_primary`: wx.Window
      :param `event`: 
      :type `event`: wx.Event




      return ``True`` if any changes in value should be reported. 



      :rtype: `bool`



                  



      .. note:: 

   

         - If property uses choice control, and displays a dialog on some choice items, then it is preferred to display that dialog in IntToValue instead of OnEvent.  











   .. 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:: RefreshChildren(self)

      Refresh values of child properties.                  

      Automatically called after value is set.                   





   .. 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` .
