What are you doing in order to update the views? I can imagine that you
can get a performance problem when you are doing something that causes
the whole document to be reformatted. 

I made some experiments with the QText stuff a week ago or so and couldn't
really make much sense from the document/view separation. For example,
the undo/redo mechanism is in the QTextEdit class, which makes no sense.
You can't have two different undo histories in different views.
I find that quite unfortunate because in principle the rich text abilities
are something really interesting. For example, for editing html text one
could mark up headings with a bigger font without developing with a
completely different codebase which is used for editing program code etc.
