documentation:

--- Adds a style value in a region of a TextEdit widget.
--- The region is specified a start and end position similarly
--- to <code>getCursorPosition</code>.
--- Different styles can be combined, e.g., to get bold blue text on a
--- red background. If <code>Bold</code>, <code>Italic</code> and
--- <code>Underline</code> are combined, currently all but one of these are
--- ignored.
--- This is an experimental function and might be changed in the future.
