[PyQt] Embedding QWidgets within a parent

Hmm, I've been through that tutorial several times, and I thought I was
getting the hang of stuff, but that tutorial doesn't seem to mention
anywhere anything about how to set parents or children. However, it seems
it might be easier than I thought it was - I hadn't realised that I could
do something like:

class webwidget(QtGui.QWidget):

  def __init__(self):
    super(webwidget, self).__init__()

    self.b = Browser()

    self.grid = QtGui.QGridLayout()


class Browser(QWebView):

    def __init__(self):

    def _result_available(self, ok):
        frame = self.page().mainFrame()

and that Google now does appear in my gui! :) (n.b. is there a better way
to do it - should I call load() somewhere else?) but, how does the comment
about children / parents relate to this?
