Re: creating hypertext documents

[Noah Levitt <nlevitt columbia edu>]

You can do basic hypertext pretty easily with a GtkTextView.
Use a tag to make the link blue and underlined, then
g_object_set_data the link target on that tag. Connect to
button release events (actually you'll probably find that
you need to connect to "event-after" and check that it's a
button release, otherwise an annoying problem comes up) and
look at the tags on the text where the click comes from. If
one of the tags has the link target in its
g_object_get_data, follow the link. Also, use motion notify
to see if the mouse is hovering over a link, and turn the
cursor into a hand. See gucharmap/gucharmap/gucharmap-charmap.c
for an example of how to do this.
