wxRichTextCtrl provides a generic implementation of a rich text editor that can handle different character
so does not behave exactly as a native wxTextCtrl, although common editing conventions
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
-be a bad choice if intended users rely on screen readers that would be unhappy

with non-native text input implementation. You might mitigate this by providing
the choice between wxTextCtrl and wxRichTextCtrl, with fewer features in the
former case.
\subsubsection{wxRichTextCtrl and styles}
-Styling attributes are represented by one of three classes: \helpref{wxTextAttr}{wxtextattr}, \helpref{wxTextAttrEx}{wxtextattrex} and \helpref{wxRichTextAttr}{wxrichtextattr}.
-wxTextAttr is shared across all controls that are derived from wxTextCtrl and

+wxTextAttr is shared across all controls that are derived from wxTextCtrlBase and
can store basic character and paragraph attributes. wxTextAttrEx derives
from wxTextAttr and adds some further attributes that are only supported
by wxRichTextCtrl. Finally, wxRichTextAttr is a more efficient version
The content is represented by a hierarchy of objects, all derived from
wxRichTextObject. An object might be an image, a fragment of text, a paragraph,

-paragraph style information is ignored by children of a paragraph (only
-character style is relevant to these objects).

images and potentially other types of object.

When Layout is called on an object, it is given a size which the object

lead to fragmentation after a lot of edit operations, potentially leading
to several objects with the same style where just one would do. So
