Re: [gtkmm] PangoStyle problem

[Vladislav Grinchenko <3rdshift comcast net>]

Mark,

I don't know if this would help you, but in my app, granule, I have 
a text and a marker:

/* DeckPlayer.h */

	Gtk::TextView m_example;

	Glib::RefPtr<Gtk::TextBuffer::TagTable> m_tag_table;
	Glib::RefPtr<Gtk::TextBuffer::Tag> m_marker;

and then initialize it to a different color (in your case it
would be italic or whaterver - just change the property):

/* DeckPlayer.cpp */

	m_tag_table = m_example.get_buffer ()->get_tag_table ();
	m_marker->property_foreground () = "red";
	m_tag_table->add (m_marker);

Then when the time comes to change the text, I apply my
marker to the region of the text:

Glib::RefPtr<Gtk::TextBuffer> text_ref = m_example.get_buffer ();
...
Gtk::TextBuffer::iterator iter = text_ref->begin ();
...
text_ref->apply_tag (m_marker, iter, iter_next);

Sometimes, to see the changes immediately, I have to drain the
event queue.

hope this helps,
-Vlad

P.S. Another thing to look at might be the set_markup() method (if it
is applicable).
