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.

Hello,
As a fairly newcomer to gtkmm.
I wonder if someone could point me in the use of tags in a textview
window.
I have a vector of strings that I wish to show in column form, similar
to say
the unix ls command.
I have examined the Textview::Tagtable in Dev help but I am still not
sure
how to place these tags in the intended buffer.
Thankyou
Mike Lear
