|phoenix_title|  **wx.richtext.RichTextSelection**
==========================================================================================================================================

Stores selection information.          

The selection does not have to be contiguous, though currently non-contiguous selections are only supported for a range of table cells (a geometric block of cells can consist of a set of non-contiguous positions). 

The selection consists of an array of ranges, and the container that is the context for the selection. It follows that a single selection object can only represent ranges with the same parent container.
