.. _wx.DataObjectSimple:

==========================================================================================================================================
|phoenix_title|  **wx.DataObjectSimple**
==========================================================================================================================================

This is the simplest possible implementation of the :ref:`wx.DataObject`  class.          

The data object of (a class derived from) this class only supports **one format**, so the number of virtual functions to be implemented is reduced. 

Notice that this is still an abstract base class and cannot be used directly, it must be derived. The objects supporting rendering the data must override :meth:`~wx.DataObjectSimple.GetDataSize`  and :meth:`~wx.DataObjectSimple.GetDataHere`  while the objects which may be set must override :meth:`~wx.DataObjectSimple.SetData`. Of course, the objects supporting both operations must override all three methods.

.. class:: wx.DataObjectSimple(DataObject)

   **Possible constructors**::

       DataObjectSimple(format=FormatInvalid)
       
       DataObjectSimple(formatName)
       
   
   This is the simplest possible implementation of the DataObject
   class.



   .. method:: __init__(self, *args, **kw)



      |overload| Overloaded Implementations:

      **~~~**

      
      **__init__** `(self, format=FormatInvalid)`
      
      Constructor accepts the supported format (none by default) which may also be set later with :meth:`SetFormat` .                  
      
      
      :param `format`: 
      :type `format`: wx.DataFormat
      
      
      
      
      
      
      **~~~**

      
      **__init__** `(self, formatName)`

   .. method:: GetAllFormats(self, dir=DataObject.Get)

                              Returns a list of wx.DataFormat objects which this data object
                              supports transferring in the given direction.  





   .. method:: GetDataHere(self, buf)

      Copies this data object's data bytes to the given buffer 

      :rtype: `bool`








   .. method:: GetDataSize(self)

      Gets the size of our data.                  

      Must be implemented in the derived class if the object supports rendering its data.                  

      :rtype: `int`








   .. method:: GetFormat(self)

      Returns the (one and only one) format supported by this object.                  

      It is assumed that the format is supported in both directions.
