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.
