    @class wxTextCtrl

    A text control allows text to be displayed and edited.

    It may be single line or multi-line. Notice that a lot of methods of the
    text controls are found in the base wxTextEntry class which is a common
    base class for wxTextCtrl and other controls using a single line text entry
    field (e.g. wxComboBox).

    @beginStyleTable
    @style{wxTE_PROCESS_ENTER}
           The control will generate the event @c wxEVT_TEXT_ENTER
           (otherwise pressing Enter key is either processed internally by the
           control or used for navigation between dialog controls).
    @style{wxTE_PROCESS_TAB}
           The control will receive @c wxEVT_CHAR events for TAB pressed -
           normally, TAB is used for passing to the next control in a dialog
           instead. For the control created with this style, you can still use
           Ctrl-Enter to pass to the next control from the keyboard.
    @style{wxTE_MULTILINE}
           The text control allows multiple lines. If this style is not
           specified, line break characters should not be used in the controls
           value.
    @style{wxTE_PASSWORD}
           The text will be echoed as asterisks.
    @style{wxTE_READONLY}
           The text will not be user-editable.
    @style{wxTE_RICH}
           Use rich text control under Win32, this allows to have more than
           64KB of text in the control even under Win9x. This style is ignored
           under other platforms.
    @style{wxTE_RICH2}
           Use rich text control version 2.0 or 3.0 under Win32, this style is
           ignored under other platforms
    @style{wxTE_AUTO_URL}
           Highlight the URLs and generate the wxTextUrlEvents when mouse
           events occur over them. This style is only supported for wxTE_RICH
           Win32 and multi-line wxGTK2 text controls.
    @style{wxTE_NOHIDESEL}
           By default, the Windows text control doesn't show the selection
           when it doesn't have focus - use this style to force it to always
           show it. It doesn't do anything under other platforms.
    @style{wxHSCROLL}
           A horizontal scrollbar will be created and used, so that text won't
           be wrapped. No effect under wxGTK1.
    @style{wxTE_NO_VSCROLL}
           For multiline controls only: vertical scrollbar will never be
           created. This limits the amount of text which can be entered into
           the control to what can be displayed in it under MSW but not under
           GTK2. Currently not implemented for the other platforms.
    @style{wxTE_LEFT}
           The text in the control will be left-justified (default).
    @style{wxTE_CENTRE}
           The text in the control will be centered (currently wxMSW and
           wxGTK2 only).
    @style{wxTE_RIGHT}
           The text in the control will be right-justified (currently wxMSW
           and wxGTK2 only).
    @style{wxTE_DONTWRAP}
           Same as wxHSCROLL style: don't wrap at all, show horizontal
           scrollbar instead.
    @style{wxTE_CHARWRAP}
           Wrap the lines too long to be shown entirely at any position
           (wxUniv and wxGTK2 only).
    @style{wxTE_WORDWRAP}
           Wrap the lines too long to be shown entirely at word boundaries
           (wxUniv and wxGTK2 only).
    @style{wxTE_BESTWRAP}
           Wrap the lines at word boundaries or at any other character if
           there are words longer than the window width (this is the default).
    @style{wxTE_CAPITALIZE}
           On PocketPC and Smartphone, causes the first letter to be
           capitalized.
    @endStyleTable

    Note that alignment styles (wxTE_LEFT, wxTE_CENTRE and wxTE_RIGHT) can be
    changed dynamically after control creation on wxMSW and wxGTK. wxTE_READONLY,
    wxTE_PASSWORD and wrapping styles can be dynamically changed under wxGTK but
    not wxMSW. The other styles can be only set during control creation.


    @section textctrl_text_format wxTextCtrl Text Format

    The multiline text controls always store the text as a sequence of lines
    separated by @c '\\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 GetInsertionPoint() or GetSelection() can @b not be used
    as indices into the string returned by GetValue() as they're going to be
    slightly off for platforms using @c "\\r\\n" as separator (as Windows
    does).

    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 GetRange(). And the indices themselves can only be passed to other
    methods, for example SetInsertionPoint() or SetSelection().

    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. This problem doesn't arise for
    single-line platforms however where the indices in the control do
    correspond to the positions in the value string.


    @section textctrl_styles wxTextCtrl Styles.

    Multi-line text controls support styling, i.e. provide a possibility to set
    colours and font for individual characters in it (note that under Windows
    @c wxTE_RICH style is required for style support). To use the styles you
    can either call SetDefaultStyle() before inserting the text or call
    SetStyle() 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
    SetDefaultStyle() doesn't change the text foreground colour (which stays
    red) while the last one doesn't change the background colour (which stays
    grey):

    @code
    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");
    @endcode


    @section textctrl_cpp_streams wxTextCtrl and C++ Streams

    This class multiply-inherits from @c std::streambuf (except for some really
    old compilers using non-standard iostream library), allowing code such as
    the following:

    @code
    wxTextCtrl *control = new wxTextCtrl(...);

    ostream stream(control)

    stream << 123.456 << " some text\n";
    stream.flush();
    @endcode

    Note that even if your compiler doesn't support this (the symbol
    @c wxHAS_TEXT_WINDOW_STREAM has value of 0 then) you can still use
    wxTextCtrl itself in a stream-like manner:

    @code
    wxTextCtrl *control = new wxTextCtrl(...);

    *control << 123.456 << " some text\n";
    @endcode

    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 @c std::cout to the text
    control. This may be done in the following way:

    @code
    #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);
    @endcode

    But wxWidgets provides a convenient class to make it even simpler so
    instead you may just do

    @code
    #include <iostream>

    wxTextCtrl *control = new wxTextCtrl(...);

    wxStreamToTextRedirector redirect(control);

    // all output to cout goes into the text control until the exit from
    // current scope
    @endcode

    See wxStreamToTextRedirector for more details.


    @section textctrl_event_handling Event Handling.

    The following commands are processed by default event handlers in
    wxTextCtrl: @c wxID_CUT, @c wxID_COPY, @c wxID_PASTE, @c wxID_UNDO, @c
    wxID_REDO. The associated UI update events are also processed
    automatically, when the control has the focus.

    @beginEventEmissionTable{wxCommandEvent}
    @event{EVT_TEXT(id, func)}
        Respond to a @c wxEVT_TEXT event, generated when the text
        changes. Notice that this event will be sent when the text controls
        contents changes -- whether this is due to user input or comes from the
        program itself (for example, if wxTextCtrl::SetValue() is called); see
        wxTextCtrl::ChangeValue() for a function which does not send this event.
        This event is however not sent during the control creation.
    @event{EVT_TEXT_ENTER(id, func)}
        Respond to a @c wxEVT_TEXT_ENTER event, generated when enter is
        pressed in a text control which must have wxTE_PROCESS_ENTER style for
        this event to be generated.
    @event{EVT_TEXT_URL(id, func)}
        A mouse event occurred over an URL in the text control (wxMSW and
        wxGTK2 only currently).
    @event{EVT_TEXT_MAXLEN(id, func)}
        This event is generated when the user tries to enter more text into the
        control than the limit set by wxTextCtrl::SetMaxLength(), see its description.

    This class can be used to (temporarily) redirect all output sent to a C++

        @c setup.h to be able to use it. Under Unix, specify @c --enable-std_iostreams
        switch when running configure for this.

    Example of usage:

    @code
    using namespace std;
    wxTextCtrl* text = new wxTextCtrl(...);
    {
        wxStreamToTextRedirector redirect(text);

        // this goes to the text control
