\section{\class{wxTextAttr}}\label{wxtextattr}

wxTextAttr represents the character and paragraph attributes, or style, for a range of text in a\rtfsp
\helpref{wxTextCtrl}{wxtextctrl}.

When setting up a wxTextAttr object, pass a bitlist mask to SetFlags to indicate
which style elements should be changed. As a convenience, when you call a
setter such as SetFont, the relevant bit will be set.

\wxheading{Typedefs}

\texttt{wxTextPos} is the type containing the index of a position in a text
control. \texttt{wxTextCoord} contains the index of a column or a row in the
control.

Note that although both of these types should probably have been unsigned, due
to backwards compatibility reasons, are defined as \texttt{long} currently.
Their use (instead of plain \texttt{long}) is still encouraged as it makes the
code more readable.

\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.

\membersection{wxTextAttr::wxTextAttr}\label{wxtextattrctor}

\func{}{wxTextAttr}{\void}

\func{}{wxTextAttr}{\param{const wxColour\& }{colText}, \param{const wxColour\& }{colBack = wxNullColour},
 \param{const wxFont\& }{font = wxNullFont}, \param{wxTextAttrAlignment }{alignment = wxTEXT\_ALIGNMENT\_DEFAULT}}

The constructors initialize one or more of the text foreground colour, background
colour, font, and alignment. The values not initialized in the constructor can be set
later, otherwise \helpref{wxTextCtrl::SetStyle}{wxtextctrlsetstyle} will use
the default values for them.


\membersection{wxTextAttr::GetAlignment}\label{wxtextattrgetalignment}

\constfunc{wxTextAttrAlignment}{GetAlignment}{\void}

Returns the paragraph alignment.


\membersection{wxTextAttr::GetBackgroundColour}\label{wxtextattrgetbackgroundcolour}

\constfunc{const wxColour\&}{GetBackgroundColour}{\void}

Return the background colour specified by this attribute.


\membersection{wxTextAttr::GetFont}\label{wxtextattrgetfont}

\constfunc{const wxFont\&}{GetFont}{\void}

Return the text font specified by this attribute.


\membersection{wxTextAttr::GetLeftIndent}\label{wxtextattrgetleftindent}

\constfunc{int}{GetLeftIndent}{\void}

Returns the left indent in tenths of a millimetre.


\membersection{wxTextAttr::GetLeftSubIndent}\label{wxtextattrgetleftsubindent}

\constfunc{int}{GetLeftSubIndent}{\void}

Returns the left sub indent for all lines but the first line in a paragraph in
tenths of a millimetre.


\membersection{wxTextAttr::GetRightIndent}\label{wxtextattrgetrightindent}

\constfunc{int}{GetRightIndent}{\void}

Returns the right indent in tenths of a millimetre.


\membersection{wxTextAttr::GetTabs}\label{wxtextattrgettabs}

\constfunc{const wxArrayInt\&}{GetTabs}{\void}

Returns the array of integers representing the tab stops. Each
array element specifies the tab stop in tenths of a millimetre.


\membersection{wxTextAttr::GetTextColour}\label{wxtextattrgettextcolour}

\constfunc{const wxColour\&}{GetTextColour}{\void}

Return the text colour specified by this attribute.


\membersection{wxTextAttr::HasAlignment}\label{wxtextattrhasalignment}

\constfunc{bool}{HasAlignment}{\void}

Returns {\tt true} if this style specifies the text alignment.

\constfunc{bool}{HasBackgroundColour}{\void}

Returns {\tt true} if this style specifies the background colour to use.


\membersection{wxTextAttr::HasFont}\label{wxtextattrhasfont}

\constfunc{bool}{HasFont}{\void}

Returns {\tt true} if this style specifies the font to use.


\membersection{wxTextAttr::HasLeftIndent}\label{wxtextattrhasleftindent}
