.. class:: wx.propgrid.IntProperty(NumericProperty)

   **Possible constructors**::

       IntProperty(label=PG_LABEL, name=PG_LABEL, value=0)
       
       IntProperty(label, name, value)
       
   
   Basic property with integer value.

      :type `label`: string

   .. method:: AddSpinStepValue(self, stepScale)

      Returns what would be the new value of the property after adding SpinCtrl editor step to the current value.                  

      Current value range and wrapping (if enabled) are taken into account. This member has to be implemented in derived properties. 




      :param `stepScale`: SpinCtrl editor step is first multiplied by this factor and next added to the current value.  
      :type `stepScale`: long






      :rtype: :ref:`PGVariant`



                  



      :returns: 

         Value which property would have after adding SpinCtrl editor step.  







      .. note:: 

         Current property value is not changed.   








   .. method:: DoGetValidator(self)

      Returns pointer to the :ref:`wx.Validator`  that should be used with the editor of this property (``None`` for no validator).                  

      Setting validator explicitly via SetPropertyValidator will override this. 

      In most situations, code like this should work well (macros are used to maintain one actual validator instance, so on the second call the function exits within the first macro): 

      ::

          class MyPropertyClass(wx.propgrid.IntProperty):
              ...
              def DoGetValidator(self):
                  validator = MyValidator(...)

                  ... prepare validator...

                  return validator



                

      :rtype: :ref:`Validator`







      .. note:: 

         You can get common filename validator by returning :meth:`wx.propgrid.FileProperty.GetClassValidator` . :ref:`wx.propgrid.DirProperty`, for example, uses it.   








   .. staticmethod:: GetClassValidator()



      :rtype: :ref:`Validator`








   .. method:: IntToValue(self, number, argFlags=0)

      Converts integer (possibly a choice selection) into :ref:`Variant`  value appropriate for this property.                  




      :param `number`: Integer to be translated into variant.   
      :type `number`: int
      :param `argFlags`: If ``PG_FULL_VALUE``  is set, returns complete, storable value instead of displayable one.  
      :type `argFlags`: int










      :rtype: `tuple`



                  



      :returns: 

         ( `bool`, `variant` ) 







      .. note:: 

   

         - If property is not supposed to use choice or spinctrl or other editor with int-based value, it is not necessary to implement this method. 
         - Default implementation simply assign given int to m_value. 
         - 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. 
         - You might want to take into account that m_value is Mull variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).  











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

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




      :param `text`: Text to be translated into variant.  
      :type `text`: string
      :param `argFlags`: If ``PG_FULL_VALUE``  is set, returns complete, storable value instead of displayable one (they may be different). If ``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:: ValidateValue(self, value, validationInfo)

      Implement this function in derived class to check the value.                  

      Return ``True`` if it is ok. Returning ``False`` prevents property change events from occurring. 

                


      :param `value`: 
      :type `value`: PGVariant
      :param `validationInfo`: 
      :type `validationInfo`: wx.propgrid.PGValidationInfo




      :rtype: `bool`







      .. note:: 

   

         - Default implementation always returns ``True``.  











   .. 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 ``PG_FULL_VALUE``  is set, returns complete, storable string value instead of displayable. If ``PG_EDITABLE_VALUE``  is set, returns string value that must be editable in textctrl. If ``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` .
