[PyQt] Self-adjusting QTextEdit (PyQt4)

Hello folks,

I'm trying to write a notecard application, somewhat in the vein of 
Evernote --- basically a succession of little textboxes, one per note, 
stacked above one another. To that end I'd like a QTextEdit (or similar) 
that adjusts its height (with given width) so that it always shows all 
its text, never more, never less.

This is what I've come up with (complete runable example attached):

class MyText(gui.QTextEdit):
    def __init__(self, parent=None):
        gui.QTextEdit.__init__(self, parent)
        self.connect(self, core.SIGNAL("textChanged()"), self.updateGeometry)
        policy = gui.QSizePolicy(gui.QSizePolicy.MinimumExpanding,
    def heightForWidth(self, w):
        return self.document().size().toSize().height()

This does not work as I hoped, naturally. :(

How would I go about this?
