|phoenix_title|  **wx.Size**
==========================================================================================================================================

A :ref:`wx.Size`  is a useful data structure for graphics operations.          

It simply contains integer `width`  and `height`  members. 

Note that the width and height stored inside a :ref:`wx.Size`  object may be negative and that :ref:`wx.Size`  functions do not perform any check against negative values (this is used to e.g. store the special -1 value in :ref:`wx.DefaultSize`  instance). See also :meth:`~wx.Size.IsFullySpecified`  and :meth:`~wx.Size.SetDefaults`  for utility functions regarding the special -1 value. 

:ref:`wx.Size`  is used throughout wxWidgets as well as :ref:`wx.Point`  which, although almost equivalent to :ref:`wx.Size`, has a different meaning: :ref:`wx.Point`  represents a position while :ref:`wx.Size`  represents the size.

      Returns ``True`` if neither of the size object components is equal to -1, which is used as default for the size values in wxWidgets (hence the predefined :ref:`wx.DefaultSize`  has both of its components equal to -1).                  

      This method is typically used before calling :meth:`SetDefaults` .                  

      :rtype: `bool`

      Scales the dimensions of this object by the given factors.

      :returns: 

         A reference to this object (so that you can concatenate other operations in the same line).

      Sets the width and height members.

   .. method:: SetDefaults(self, sizeDefault)

      Combine this size object with another one replacing the default (i.e. equal to -1) components of this object with those of the other.                  

      It is typically used like this: 

      ::

                  if not size.IsFullySpecified():

                      size.SetDefaults(GetDefaultSize())



                


      :param `sizeDefault`: 
      :type `sizeDefault`: wx.Size
