+
+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.

+\texttt{wxTextPos} is the type containing the index of a position in a text

+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

+See also \helpref{window styles overview}{windowstyles} and

+
+\wxheading{wxTextCtrl text format}
+
+The multiline text controls always store the text as a sequence of lines
+separated by {\tt $\backslash$n} characters, i.e. in the Unix text format even
+on non-Unix platforms. This allows the user code to ignore the differences
+between the platforms but at a price: the indices in the control such as those
+returned by \helpref{GetInsertionPoint}{wxtextctrlgetinsertionpoint} or
+\helpref{GetSelection}{wxtextctrlgetselection} can {\bf not} be used as
+indices into the string returned by \helpref{GetValue}{wxtextctrlgetvalue} as
+they're going to be slightly off for platforms using
+{\tt $\backslash$r$\backslash$n} as separator (as Windows does), for example.
+
+Instead, if you need to obtain a substring between the $2$ indices obtained
+from the control with the help of the functions mentioned above, you should
+use \helpref{GetRange}{wxtextctrlgetrange}. And the indices themselves can
+only be passed to other methods, for example
+\helpref{SetInsertionPoint}{wxtextctrlsetinsertionpoint} or
+\helpref{SetSelection}{wxtextctrlsetselection}.
+
+To summarize: never use the indices returned by (multiline) wxTextCtrl as
+indices into the string it contains, but only as arguments to be passed back
+to the other wxTextCtrl methods.
+
+\wxheading{wxTextCtrl styles}
+
+Multi-line text controls support the styles, i.e. provide a possibility to set
+colours and font for individual characters in it (note that under Windows {\tt
+wxTE\_RICH} style is required for style support). To use the styles you can
+either call \helpref{SetDefaultStyle}{wxtextctrlsetdefaultstyle} before
+inserting the text or call \helpref{SetStyle}{wxtextctrlsetstyle} later to
+change the style of the text already in the control (the first solution is
+much more efficient).
+
+In either case, if the style doesn't specify some of the attributes (for
+example you only want to set the text colour but without changing the font nor
+the text background), the values of the default style will be used for them.
+If there is no default style, the attributes of the text control itself are
+used.
+
+So the following code correctly describes what it does: the second call
+to \helpref{SetDefaultStyle}{wxtextctrlsetdefaultstyle} doesn't change the
+text foreground colour (which stays red) while the last one doesn't change the
+background colour (which stays grey):
-\wxheading{Remarks}
+{\small%
+\begin{verbatim}
+ text->SetDefaultStyle(wxTextAttr(*wxRED));
+ text->AppendText("Red text\n");
+ text->SetDefaultStyle(wxTextAttr(wxNullColour, *wxLIGHT_GREY));
+ text->AppendText("Red on grey text\n");
+ text->SetDefaultStyle(wxTextAttr(*wxBLUE);
+ text->AppendText("Blue on grey text\n");

+Note that independently of this setting you can always use wxTextCtrl itself
+in a stream-like manner:
+
+{\small%
+\begin{verbatim}
+ wxTextCtrl *control = new wxTextCtrl(...);
+
+ *control << 123.456 << " some text\n";
+\end{verbatim}
+}%
+
+always works. However the possibility to create an ostream associated with
+wxTextCtrl may be useful if you need to redirect the output of a function
+taking an ostream as parameter to a text control.
+
+Another commonly requested need is to redirect {\bf std::cout} to the text
+control. This could be done in the following way:
+
+{\small%
+\begin{verbatim}
+ #include <iostream>
+
+ wxTextCtrl *control = new wxTextCtrl(...);
+
+ std::streambuf *sbOld = std::cout.rdbuf();
+ std::cout.rdbuf(*control);
+
+ // use cout as usual, the output appears in the text control
+ ...
+
+ std::cout.rdbuf(sbOld);
+\end{verbatim}
+}%
+
+But wxWidgets provides a convenient class to make it even simpler so instead
+you may just do
+
+{\small%
+\begin{verbatim}
+ #include <iostream>
+
+ wxTextCtrl *control = new wxTextCtrl(...);
+
+ wxStreamToTextRedirector redirect(control);
+
+ // all output to cout goes into the text control until the exit from current
+ // scope
+\end{verbatim}
+}%
+
+See \helpref{wxStreamToTextRedirector}{wxstreamtotextredirector} for more
+details.
+
+\wxheading{Event handling}
+
+The following commands are processed by default event handlers in wxTextCtrl: wxID\_CUT, wxID\_COPY,
+wxID\_PASTE, wxID\_UNDO, wxID\_REDO. The associated UI update events are also processed
+automatically, when the control has the focus.
+
+To process input from a text control, use these event handler macros to direct input to member
+functions that take a \helpref{wxCommandEvent}{wxcommandevent} argument.

Returns the number of lines in the text control buffer.
+\wxheading{Remarks}
+
+Note that even empty text controls have one line (where the insertion point
+is), so GetNumberOfLines() never returns 0.
+
+For gtk\_text (multi-line) controls, the number of lines is
+calculated by actually counting newline characters in the buffer. You
+may wish to avoid using functions that work with line numbers if you are
+working with controls that contain large amounts of text.
+
+
+\membersection{wxTextCtrl::GetRange}\label{wxtextctrlgetrange}
+
+\constfunc{virtual wxString}{GetRange}{\param{long}{ from}, \param{long}{ to}}
+
+Returns the string containing the text staring in the positions {\it from} and
+up to {\it to} in the control. The positions must have been returned by another
+wxTextCtrl method.
+
+Please note that the positions in a multiline wxTextCtrl do {\bf not}
+correspond to the indices in the string returned by
+\helpref{GetValue}{wxtextctrlgetvalue} because of the different new line
+representations ({\tt CR} or {\tt CR LF}) and so this method should be used to
+obtain the correct results instead of extracting parts of the entire value. It
+may also be more efficient, especially if the control contains a lot of data.
+
+
+\membersection{wxTextCtrl::GetSelection}\label{wxtextctrlgetselection}
+
+\constfunc{virtual void}{GetSelection}{\param{long*}{ from}, \param{long*}{ to}}
+
+Gets the current selection span. If the returned values are equal, there was
+no selection.
+
+Please note that the indices returned may be used with the other wxTextctrl
+methods but don't necessarily represent the correct indices into the string
+returned by \helpref{GetValue()}{wxtextctrlgetvalue} for multiline controls
+under Windows (at least,) you should use
+\helpref{GetStringSelection()}{wxtextctrlgetstringselection} to get the selected
+text.
+
+\wxheading{Parameters}
+
+\docparam{from}{The returned first position.}
+
+\docparam{to}{The returned last position.}
+
+\pythonnote{The wxPython version of this method returns a tuple

+\constfunc{wxTextCtrlHitTestResult}{HitTest}{\param{const wxPoint\& }{pt}, \param{wxTextCoord }{*col}, \param{wxTextCoord }{*row}}

+If {\it len} is $0$, the previously set max length limit, if any, is discarded
+and the user may enter as much text as the underlying native text control
+widget supports (typically at least 32Kb).
+
+If the user tries to enter more characters into the text control when it
+already is filled up to the maximal length, a
+{\tt wxEVT\_COMMAND\_TEXT\_MAXLEN} event is sent to notify the program about it
+(giving it the possibility to show an explanatory message, for example) and the
