|phoenix_title|  **wx.grid.GridBlocks**
==========================================================================================================================================

Represents a collection of grid blocks that can be iterated over.          

This class provides read-only access to the blocks making up the grid selection in the most general case. 

Note that objects of this class can only be returned by :ref:`wx.grid.Grid`, but not constructed in the application code. 

The preferable way to iterate over it is using ``C++11`` range-for loop: ::

# For Python the returned GridBlocks object has a __iter__ method so iterating
# in the Python way is possible.
for block in self.grid.GetSelectedBlocks():
    do_something(block)

When not using ``C++11``, iteration has to be done manually: ::
