## rich-edit-pane

A `text-edit-pane` that will automatically link up with any rich-edit formatting controls that are either on the same parent or on a toolbar of the parent. This is the class of widget-windows that are instantiated whenever a `rich-edit` is added to a window. Probably not of concern to applications unless it needs to intercept low-level window events of a `rich-edit` subclass or otherwise add methods to the widget-window of a `rich-edit`. See `os-widget-window`.

The character index at a specific position is returned by character-index-at-position and the location of that character (given the index) is returned by position-of-character-index.

See cg-rich-text.htm for information about rich text editing in Common Graphics.

A diagram of window and widget classes is shown in Widget and window classes in cgide.htm.

### GTK note

Formated editable text is not yet implemented on the GTK platform. It appears feasible to implement functions such as set-character-format and set-paragraph-format that modify the text formatting of an edit control, but not to implement functions such as rich-text and rich-edit-range that handle actual rich text strings.

Attempting to create a `rich-edit` widget or a `rich-edit-pane` window currently will error on GTK.
