# `wxStyledTextCtrl`
[🔗](https://github.com/erlang/otp/blob/OTP-29.0.3/lib/wx/src/gen/wxStyledTextCtrl.erl#L58)

A wxWidgets implementation of the Scintilla source code editing component.

As well as features found in standard text editing components, Scintilla includes
features especially useful when editing and debugging source code. These include support
for syntax styling, error indicators, code completion and call tips.

The selection margin can contain markers like those used in debuggers to indicate
breakpoints and the current line. Styling choices are more open than with many editors,
allowing the use of proportional fonts, bold and italics, multiple foreground and
background colours and multiple fonts.

`m:wxStyledTextCtrl` is a 1 to 1 mapping of "raw" scintilla interface, whose
documentation can be found in the Scintilla website ([http://www.scintilla.org/](http://www.scintilla.org/)).

Please see `m:wxStyledTextEvent` for the documentation of all event types you can use
with `m:wxStyledTextCtrl`.

This class is derived, and can use functions, from:

* `m:wxControl`

* `m:wxWindow`

* `m:wxEvtHandler`
