just call:
domDocu= part.document ()
html= domDocu.toString ().string ()
that's a QString.

yes, under certain circumstances that happens. I think it's because
the KHTMLPart has no parentWidet or no parent or both. if you setup the
whole apparatus for showing the part, everythings works just fine.
Thanks a lot Marcos. I was using Jim Bublitz's
doc/examples/pyKHTMLPart.py and modified it from there. It appears to
me that parentWidget for the KHTMLPart is not 0:
class pyPartsMW(KParts.MainWindow):
def __init__(self, *args):
...
self.w = KHTMLPart(self, "HTMLart", self)
self.w.openURL (KURL("http://www.kde.org";))
domDocu = self.w.document ()
html = domDocu.toString().string()
...
Then I got the error message:
terminate called after throwing an instance of 'DOM::DOMException'
where .toString() is called. Is there any other reason leading to this
other than the 0 values when initiate the KHTMLPart object?
