\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.

\func{void}{SetPageBreak}{\param{bool}{ pageBreak = true}}

Specifies a page break before this paragraph.

#define wxTEXT_ATTR_EFFECT_CAPITALS                 0x00000001
#define wxTEXT_ATTR_EFFECT_SMALL_CAPITALS           0x00000002
#define wxTEXT_ATTR_EFFECT_STRIKETHROUGH            0x00000004
#define wxTEXT_ATTR_EFFECT_DOUBLE_STRIKETHROUGH     0x00000008
#define wxTEXT_ATTR_EFFECT_SHADOW                   0x00000010

}

Of these, only wxTEXT\_ATTR\_EFFECT\_CAPITALS and wxTEXT\_ATTR\_EFFECT\_STRIKETHROUGH are implemented.
wxTEXT\_ATTR\_EFFECT\_CAPITALS capitalises text when displayed (leaving the case of the actual buffer
text unchanged), and wxTEXT\_ATTR\_EFFECT\_STRIKETHROUGH draws a line through text.

To set effects, you should also pass wxTEXT\_ATTR\_EFFECTS to \helpref{wxTextAttr::SetFlags}{wxtextattrsetflags}, and call\rtfsp
\helpref{wxTextAttrEx::SetTextEffectFlags}{wxtextattrexsettexteffectflags} with the styles (taken from the
above set) that you are interested in setting.

\membersection{wxTextAttrEx::SetURL}\label{wxtextattrexseturl}

\func{void}{SetURL}{\param{const wxString\& }{url}}

Sets the URL for the content. Sets the wxTEXT\_ATTR\_URL style; content with this style
causes wxRichTextCtrl to show a hand cursor over it, and wxRichTextCtrl generates
a wxTextUrlEvent when the content is clicked.

\membersection{wxTextAttrEx::operator=}\label{wxtextattrexoperatorassign}

\func{void operator}{operator=}{\param{const wxTextAttr\& }{attr}}

Assignment from a wxTextAttr object.

\func{void operator}{operator=}{\param{const wxTextAttrEx\& }{attr}}
