[gtkmm] How to set visible cursor position

[DarkDragon <darkdragon ghost pl>]

I'd like to pass the TextView's TextBuffer word by word,
placeing the cursor and view to current word and tagging it red.
Is there an example of doing such a thing? I managed to do tagging and
iterating
word by word, but do not know how to change cursor and view position.
Any help wold be appreciated:)
