\section{\class{wxTextAttrEx}}\label{wxtextattrex}
wxTextAttrEx is an extended version of wxTextAttr with more paragraph attributes.
Currently it is only used with \helpref{wxRichTextCtrl}{wxrichtextctrl}.
It is intended that eventually, the members of wxTextAttrEx will
be folded into wxTextAttr, and wxTextAttr will be the official
cross-platform API for text controls that support attributes.
However, for now, wxTextAttrEx is provided as a means of enabling
extra functionality in wxRichTextCtrl, while retaining some compatibility
with the wxTextAttr API.
The most efficient method of accessing wxRichTextCtrl functionality
is a third attribute class, \helpref{wxRichTextAttr}{wxrichtextattr}, which
optimizes its storage to allow it to be used for implementing objects
in a buffer, as well as access to that buffer.
This section only documents the additional members; see \helpref{wxTextAttr}{wxtextattr} for
the remaining functions.

\wxheading{Constants}
The following values can be passed to SetAlignment to determine
paragraph alignment.
{\small
\begin{verbatim}
enum wxTextAttrAlignment
{
wxTEXT_ALIGNMENT_DEFAULT,
wxTEXT_ALIGNMENT_LEFT,
wxTEXT_ALIGNMENT_CENTRE,
wxTEXT_ALIGNMENT_CENTER = wxTEXT_ALIGNMENT_CENTRE,
wxTEXT_ALIGNMENT_RIGHT,
wxTEXT_ALIGNMENT_JUSTIFIED
};
\end{verbatim}
}
These values are passed in a bitlist to SetFlags to determine
what attributes will be considered when setting the attributes
for a text control.
