StyledTextEditor is an enhanced Gtk.TextView to edit :class:`.StyledText`.
StyledTextEditor is a gui object for :class:`.StyledTextBuffer`. It offers
:meth:`set_text` and :meth:`get_text` convenience methods to set and get the
buffer's text.
StyledTextEditor provides a formatting toolbar, which can be retrieved
by the :meth:`get_toolbar` method.
StyledTextEdit defines a new signal: 'match-changed', which is raised
whenever the mouse cursor reaches or leaves a matched string in the text.
The feature uses the regexp pattern mathing mechanism of
:class:`.StyledTextBuffer`.
The signal's default handler highlights the URL strings. URL's can be
followed from the editor's popup menu or by pressing the <CTRL>Left
mouse button.
:ivar last_match: previously matched string, used for generating the
'match-changed' signal.
