HI Mike,
Text Tags are applied to the TextBuffer, once the text is loaded
into it. I use the Gtk::TextBuffer::create_tag() function, so the
tag is created and added to the textbuffer immediately, which
seems more convenient than constructing the tag and then adding it
to the buffer separately.
some sample code:
Gtk::TextView* AView = Gtk::manage(new Gtk::TextView());
Glib::RefPtr< Gtk::TextBuffer > ABuff =
AView->get_buffer();
Glib::RefPtr<Gtk::TextBuffer::Tag> refTagBold =
ABuff->create_tag();
refTagBold->property_weight() = Pango::WEIGHT_ULTRABOLD;
//set the text in the buffer, and identify what you want to
apply a tag to; then:
Gtk::TextBuffer::iterator start_it =
ABuff->get_iter_at_offset(start_of_highlight);
Gtk::TextBuffer::iterator end_it =
ABuff->get_iter_at_offset(end_of_highlight);
ABuff->apply_tag(refTagBold, start_it, end_it);
Ian.
