I haven't used the text buffer/view to do anything very
sophisticated.  This is just a suggestion:

At the position in the text buffer where the text should go, insert
two GtkTextMark objects (you'll need to get a GtkTextIter at this
position first).  Store these in the object containing/derived from
GtkTextBuffer/View, and create methods that use them:

Now you have the marks, you can keep them there for the lifetime of
the object.  When it comes to inserting text, you can delete the text
between the marks using gtk_text_buffer_delete() (convert them both to
iterators first).  Next, you can insert the new text between them
using gtk_text_buffer_insert().

This is just from reading the API reference.  You'll need to test it
first, but it should be fairly straightforward.


Regards,
Roger
