I don't see any import of qt4reactor or Twisted (other than the implied import of Deferred) in this code. Firing a Deferred in this way should be totally fine though; you don't actually need the reactor for Deferreds to work (it's just important that if it's going to interact with any other Twisted code it needs to run on the main thread). Sorry I don't have a better suggestion, but I don't see much wrong with what you're doing here :). -g > url = 'http://www.google.com <http://www.google.com/>' > > mo = """ > var observer = new MutationObserver(function(mutations) { > for (var x = 0; x < mutations.length; x++) { > if (mutations[x].addedNodes.length > 0) { > alert('add nodes') > } > } > }); > var config = { attributes: true, childList: true, characterData: false } > var nti = document.querySelector('document.body') > observer.observe(nti, config); > """ > > page = QWebPage() > def alarmAction(qframe, msg): > print 'deferred action', qframe, msg > def mutationHook(): > d = defer.Deferred() > d.addCallback(alarmAction) > page.javaScriptAlert = d.callback > page.mainFrame().documentElement().evaluateJavaScript(mo) > > page.loadFinished(mutationHook) > page.mainFrame().setUrl(url) > > _______________________________________________ > Twisted-Python mailing list > Twisted-Python@twistedmatrix.com > http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
