wxRichTextCtrl provides a generic, ground-up implementation of a text control
capable of showing multiple styles and images.
+wxRichTextCtrl sends notification events: see \helpref{wxRichTextEvent}{wxrichtextevent}.
+It also sends the standard wxTextCtrl events wxEVT\_COMMAND\_TEXT\_ENTER and wxEVT\_COMMAND\_TEXT\_UPDATED,
+and wxTextUrlEvent when URL content is clicked.
+
+For more information, see the \helpref{wxRichTextCtrl overview}{wxrichtextctrloverview}.

function that takes a wxRichTextEvent argument.

wxRichTextCtrl provides a generic implementation of a rich text editor that can handle different character

are followed. Users may miss the built-in spelling correction on Mac OS X, or any
special character input that may be provided by the native control. It would also

the choice between wxTextCtrl and wxRichTextCtrl, with fewer features in the
former case.
