.. _wx.Object:

==========================================================================================================================================
|phoenix_title|  **wx.Object**
==========================================================================================================================================

This is the root class of many of the wxWidgets classes.          

It declares a virtual destructor which ensures that destructors get called for all derived class objects where necessary. 

:ref:`wx.Object`  is the hub of a dynamic object creation scheme, enabling a program to create instances of a class only knowing its string class name, and to query the class hierarchy. 

The class contains optional debugging versions of **new**  and **delete**, which can help trace memory allocation and deallocation problems. 

:ref:`wx.Object`  can be used to implement :ref:`reference counted <reference counting>`  objects, such as :ref:`wx.Pen`, :ref:`wx.Bitmap`  and others (see :ref:`this list <stock items>`). See :ref:`wx.RefCounter`  and :ref:`Reference Counting <reference counting>`  for more info about reference counting.

================================================================================ ================================================================================

.. class:: wx.Object(object)

   **Possible constructors**::

       Object()
       
       Object(other)
       
   
   This is the root class of many of the wxWidgets classes.



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



      |overload| Overloaded Implementations:

      **~~~**

      
      **__init__** `(self)`
      
      Default constructor; initializes to ``None`` the internal reference data.                   
      
      
      
      
      **~~~**

      
      **__init__** `(self, other)`
      
      Copy constructor.                  
      
      Sets the internal ``Object.m_refData``  pointer to point to the same instance of the ObjectRefData-derived class pointed by  ``other``   and increments the refcount of  ``Object.m_refData``.                  
      
      
      :param `other`: 
      :type `other`: wx.Object
      
      
      
      
      
      
      **~~~**






   .. method:: Destroy(self)

      Deletes the C++ object this Python object is a proxy for.  





   .. method:: GetClassName(self)

      Returns the class name of the C++ class using ``RTTI``. 

      :rtype: :ref:`wx.Char`








   .. method:: GetRefData(self)

      Returns the ``Object.m_refData``  pointer, i.e. the data referenced by this object.                  

                

      :rtype: :ref:`wx.ObjectRefData`







      .. seealso:: :meth:`Ref` , :meth:`UnRef` , ``Object.m_refData``, :meth:`SetRefData` , :ref:`wx.ObjectRefData`    








   .. method:: IsSameAs(self, obj)

      Returns ``True`` if this object has the same data pointer as `obj`.                  

      Notice that ``True`` is returned if the data pointers are ``None`` in both objects. 

      This function only does a `shallow`  comparison, i.e. it doesn't compare the objects pointed to by the data pointers of these objects. 

                


      :param `obj`: 
      :type `obj`: wx.Object




      :rtype: `bool`







      .. seealso:: :ref:`Reference Counting <reference counting>`    








   .. method:: Ref(self, clone)

      Makes this object refer to the data in `clone`.                  




      :param `clone`: The object to 'clone'.  
      :type `clone`: wx.Object




                  



      .. note:: 

         First this function calls :meth:`UnRef`   on itself to decrement (and perhaps free) the data it is currently referring to. It then sets its own ``Object.m_refData``  to point to that of `clone`, and increments the reference count inside the data.  







      .. seealso:: :meth:`UnRef` , :meth:`SetRefData` , :meth:`GetRefData` , :ref:`wx.ObjectRefData`    








   .. method:: SetRefData(self, data)

      Sets the ``Object.m_refData``  pointer.                  

                


      :param `data`: 
      :type `data`: wx.ObjectRefData






      .. seealso:: :meth:`Ref` , :meth:`UnRef` , :meth:`GetRefData` , :ref:`wx.ObjectRefData`    








   .. method:: UnRef(self)

      Decrements the reference count in the associated data, and if it is zero, deletes the data.                  

      The ``Object.m_refData``  member is set to ``None``. 

                 



      .. seealso:: :meth:`Ref` , :meth:`SetRefData` , :meth:`GetRefData` , :ref:`wx.ObjectRefData`    








   .. method:: UnShare(self)

      This is the same of :meth:`AllocExclusive`   but this method is public.                   





   .. attribute:: ClassName

      See :meth:`~wx.Object.GetClassName`


   .. attribute:: RefData
