  • PyQt4.QtWebKit.QWebFrame missing findAllElements() method on debian

    - by user249095
    I recompiled PyQt4 from source, but the issue still exists. On another ArchLinux system, it works well. Can someone help me? Thanks! on Debian: import PyQt4.QtWebKit dir(PyQt4.QtWebKit.QWebFrame.findAllElements) Traceback (most recent call last): File "", line 1, in AttributeError: type object 'QWebFrame' has no attribute 'findAllElements' on ArchLinux: import PyQt4.QtWebKit dir(PyQt4.QtWebKit.QWebFrame.findAllElements) ['__call__', '__class__', '__cmp__', '__delattr__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__le__', '__lt__', '__module__', '__name__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__self__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

  • ImportError: No module named QtWebKit

    - by Hallik
    I am on centos5. I installed python26 source with a make altinstall. Then I did a: yum install qt4 yum install qt4-devel yum install qt4-doc From riverbankcomputing.co.uk I downloaded the source for sip 4.10.2, compiled and installed fine. Then from the same site I downloaded and compiled from source PyQt-x11-4.7.3 Both installs were using the python26 version (/usr/local/bin/python2.6). So configure.py, make, and make install worked with no errors. Finally, I tried to run this script, but got the error in the subject of this post: import sys import signal from PyQt4.QtCore import * from PyQt4.QtGui import * from PyQt4.QtWebKit import QWebPage def onLoadFinished(result): if not result: print "Request failed" sys.exit(1) #screen = QtGui.QDesktopWidget().screenGeometry() size = webpage.mainFrame().contentsSize() # Set the size of the (virtual) browser window webpage.setViewportSize(webpage.mainFrame().contentsSize()) # Paint this frame into an image image = QImage(webpage.viewportSize(), QImage.Format_ARGB32) painter = QPainter(image) webpage.mainFrame().render(painter) painter.end() image.save("output2.png") sys.exit(0) app = QApplication(sys.argv) signal.signal(signal.SIGINT, signal.SIG_DFL) webpage = QWebPage() webpage.connect(webpage, SIGNAL("loadFinished(bool)"), onLoadFinished) webpage.mainFrame().load(QUrl("http://www.google.com")) sys.exit(app.exec_()) Even in the beginning of the configure for pyqt4, I saw it say QtWebKit should be installed, but apparently it's not? What's going on? I just did a find, and it looks like it wasn't installed. What are my options? [root@localhost ~]# find / -name '*QtWebKit*' /root/PyQt-x11-gpl-4.7.3/sip/QtWebKit /root/PyQt-x11-gpl-4.7.3/sip/QtWebKit/QtWebKitmod.sip /root/PyQt-x11-gpl-4.7.3/cfgtest_QtWebKit.cpp

  • QTWebkit 4.6 and ico images, Rendering problem

    - by Red Serpent
    Hi I have a local html file which I'm trying to view using QTWebKit, there are some images in the file which are of type ".ico" which seems that QTWebKit is not able to render them as it gives a question mark icon instead. I tried opening the html file in firefox and its working fine and all images gets rendered. My question is, does QTWebKit support ico images, and if it does... what should I do to enable webkit to render ico images? Regards

  • Nokia annonce les prochaines versions de QtWebKit, QtWebKit 2.1 apportera le support de HTML5 sur Symbian et MeeGo

    Nokia annonce les prochaines versions de QtWebKit QtWebKit 2.1 apportera le support de HTML5 sur Symbian et MeeGo Mise à jour du 08/03/2011 par dourouc05 Après avoir été projet pionnier de la modularisation de Qt, qui devrait arriver pour Qt 4.8, QtWebKit fait enfin à nouveau entendre parler de lui, en annonçant les prochaines versions. QtWebKit 2.1 se focalisera sur le support des plateformes Nokia (c'est-à-dire Symbian et MeeGo), toujours en se basant sur Qt 4.7. Il corrigera un certain nombre de bogues et apportera le support d'un certain nombre d'éléments de HTML5. QtWebKit 2.2 sera, quant à lui, dirigé vers Qt...

  • Is QTWebKit still being actively developed? [closed]

    - by Brian M. Hunt
    I am considering recommending PhantomJS/CasperJS for a project, to provide continuous integration testing. Unfortunately those testing frameworks are based on QTWebKit, and it does not appear that there has been much activity on QTWebKit since September of 2011. It seems this is because of Nokia's financial troubles. QT has since been sold to Digia in August of this year, and can be found on qt.digia.com. It is not apparent whether QTWebKit will be actively developed. Before putting the effort into developing a PhantomJS/CasperJS testing framework, I would like to know whether the underlying QTWebKit framework is probably going to continue to be actively developed (or, alternatively, could be easily substituted with an alternative). I would suspect that since Digia just acquired QT it is a little too soon to tell what direction they will take the project. I would be interested in thoughts and comments on this issue.

  • Display using QtWebKit, whilst parsing xml

    - by Beren Scott
    I wish to use QtWebKit to load a url for display, but, that's the easy part, I can do that. What I wish to do is record / log xml as I go. My attention here is to record and database certain details on the fly, by recording those details. My problem is, how to do this all on the fly, without requesting the same url from the server twice, once for the xml, and the second time to view the url. My hope here, is to implement a very fast way of recording set data as the user passes over it. Take for example, rather then have to type out details displayed by a website, I wish to have those details chucked into a database as I the user views the website. Now, I am using QtWebKit, and I have everything pretty much solved viewing wise. I have a loadUrl() routine which calls load(url) inside the qwebview.h The problem is, how do I piggyback xml parsing on top of this?

  • QtWebKit problems playing HTML5 video

    - by oskar
    I have a simple Qt application that launches a window with a QWebView. I tried several sites using the video tag with h.264, and it either can't play the video at all (as in youtube or sublime video), or it renders the video poorly, with black lines covering parts of it, like when viewing the video here. Is this a known issue with QtWebKit, or have I neglected to do something that would make it work better? My code is below. #include <QtGui/QApplication> #include <QWebView> int main(int argc, char *argv[]) { QApplication a(argc, argv); QWebView *view = new QWebView(); view->load(QUrl("http://webkit.org/blog/140/html5-media-support/")); view->show(); return a.exec(); }

  • Very slow remote page load performance in QtWebKit (Windows)

    - by Gil
    I get very slow load times on QtWebKit on Windows 7, through ADSL. I am using the Qt Demo Browser, on a Core2 Quad, 64 bit Windows 7, 4GB ram, 2gb processor. through a VPN. Simplest example: google search page takes ~18 seconds to load, compared to 2.5 on Chrome (cash cleared). On larger pages, with scripts etc. it is worse. I tried Qt 4.6 and also the Qt 4.7 beta, but don't see any difference. I see the same results with Arora browser. Are there any settings, or patches that can be applied to fix this? Thanks

  • QtWebkit and hasPendingEvents() always True

    - by Deorf
    Hello. I use project webkit2png (slightly appended) to take screenshots in Linux. On the server running the latest version QtWebkit and Python 2.6 On some sites (eg 118114.cn) problem and the application hangs forever. Debug shows that the problem in this code snippet: while self.__loading:    if timeout 0 and time.time() = cancelAt:       raise RuntimeError("Request timed out on %s" % url)    while QApplication.hasPendingEvents():       QCoreApplication.processEvents() Full version of the source code is available here (lines 270-275) Somehow Loading-event hangs and hasPendingEvents can not be False. Most of the screenshots are created normally, but sometimes due to some URL drops my app: ( Does anyone know how to solve this problem and why the event hangs?

  • Retrieve position of a google maps v3 marker to Qt in a desktop app with QtWebKit

    - by nelas
    I'm building a Qt app with Python where you can point and click at a (google) map and get the coordinates of the location. The map is shown through a QWebView loading a simple HTML page and the user can create markers by clicking. Screenshot of the widget after clicking on the map: However, I'm having trouble to retrieve the just-clicked location coordinates back to Qt (so that I can use them as variables -- and, for example, show them in the QLineEdits on the topleft corner above, as current location of the marker). This is the relevant part of the HTML file: <script type="text/javascript"> var map; function initialize() { var local = new google.maps.LatLng(-23.4,-40.3); var myOptions = { zoom: 5, center: local, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); google.maps.event.addListener(map, 'rightclick', function(event) { placeMarker(event.latLng); }); } function placeMarker(location) { var clickedLocation = new google.maps.LatLng(location); var marker = new google.maps.Marker({ position: location, map: map }); map.setCenter(location); } function dummyTxt() { return 'This works.'; } </script> I've been trying with evaluateJavaScript, but was not able to retrieve the coordinates. I tried to created a function to access the position with marker.getPosition(), but with no luck. The dummy below works though.. newplace = QWebView.page().mainFrame().evaluateJavaScript(QString('dummyTxt()')) >>> print newplace.toString() This works. Any suggestions on how to get the coordinates back to Qt?

  • LIbrary issue: How do I set up QtWebKit to parse HTML?

    Nick Presta showed that you can parse HTML with qt here: Library Recommendation: C++ HTML Parser However, when I attempt to build this, I get an access violation on the "QWebFrame* frame = page.mainFrame();" line.

  • Is there a summary of differences in rendering/behavior between QtWebKit and Chrome/Safari WebKit?

    - by Gil
    I wrote a simple Qt application (Windows+Mac) that uses QtWebKit to render a web site inside a window. But I already saw differences in layout and behavior between our app and Chrome (that uses WebKit as well), e.g.: - different fonts are displayed for the same web page - an html anchor link with "javascript:someFunction()" is not working Is there somewhere a summary list of all such differences (not the entire QtWebKit bug list)? Also: is there a way to use a WebKit version more similar to Chrome in my application?

  • Automatic multi-page multi-column flowing text with QtWebkit (HTML/CSS/JS -> PDF)

    - by Peter Boughton
    I have some HTML documents that are converted to PDF, using software that renders using QtWebkit (not sure which version). Currently, the documents have specific tags to split into columns and pages - so whenever the wording changes, it is a manual time-consuming process to move these tags so that the columns and pages fit. Can anyone provide a way to have text auto-wrapped into the next column/page (as appropriate) when it reaches the bottom of the current container? Any HTML, CSS or JS supported by QtWebkit is ok (assuming it works in the PDF converter). (I have tested the webkit-column-* in CSS3 and it appears QtWebkit does not support this.) To make things more exciting, it also needs to: - put a header at the top of each page, with page X of Y numbering; - if an odd number of pages, add a blank page at the end (with no header); - have the ability to say "don't break inside this block" or "don't break after this header" I have put some quick example initial markup and target markup to help explain what I'm trying to do. (The actual documents are far more complicated than that, but I need a simple proof-of-concept before I attack the real ones.) Any suggestions? Update: I've got a partially working solution using Aaron's "filling up" suggestion - I'll post more details in a bit.

  • Utiliser QML et QtWebKit avec PySide, le binding Python de Qt, un article traduit par Thibaut Cuvelier

    Ce tutoriel sur PySide montre comment intégrer du code Python et QtWebKit avec QML. Le résultat sera un contenu HTML et une logique dans une application QML, tout en pouvant envoyer des messages entre le contexte JavaScript de la QWebView et le monde Python. Il utilisera JSON, alert() et evaluateJavaScript() pour échanger des structures de données arbitraires (valeurs, listes, dictionnaires) entre Python et JavaScript dans la QWebView.

  • Trying to issue a mouseclick event on a QWebElement in QWebView QtWebKit

    - by Bad Man
    I'm trying to send a mouse click event on a certain element in the QtWebKit DOM but I'm obviously doing it wrong: QWebElement el=this->page()->mainFrame()->findFirstElement("input[type=submit]"); el.setFocus(); QMouseEvent pressEvent(QMouseEvent::MouseButtonPress, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this->page()->mainFrame(), &pressEvent); QMouseEvent releaseEvent(QMouseEvent::MouseButtonRelease, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this->page()->mainFrame(), &releaseEvent); Any ideas? (p.s. I am extending QWebView if it wasn't obvious)

  • Capture Flash Audio in 4.7 Edge?

    - by emcmanus
    Is there a way to capture plugin (Flash) audio before it gets to the sound card? I'd like to record plugin audio, hopefully without actually playing the sound. Capturing audio at the device level is an absolute last resort, as the application would pick up all system audio rather than just the Webkit plugin. I'm aware of the recent switch back from QTMultimedia; is this possible with phonon? I spent the night looking for some way to access the phonon graph via QWebFrame (or any of the QtWebkit widgets) -- and didn't turn up much. I also started digging through QTWebkit, particularly NPAPI, without success. For reference, I'm using the edge version of 4.7 (6aa50af000f85cc4497749fcf0860c8ed244a60e) This seems to be a fairly challenging problem. Any hints would be greatly appreciated.

  • QWebFrame::evaluateJavaScript vs. script-tag in HTML

    - by jwg
    Hi, I want to develop an application that uses QtWebKit and JQuery. What I need to know is, is there any difference between reading JQuery from a file and evaluateJavaScript it, or embedding it as a script tag within the "page" that is displayed within the widget? If there is a difference, I am curious if anyone could explain why it would be. As far as I understood it, evaluateJavaScript() would feed the script parameter to the JavaScript interpreter, which interprets it in the current page's context. Thanks.

  • Qt: Force QWebView to click on a web element, even one not visible on the window

    - by Pirate for Profit
    So let's say I'm trying to click a link in the QWebView, here is what I have: // extending QWebView void MyWebView::click(const QString &selectorQuery) { QWebElement el = this->page()->mainFrame()->findFirstElement(selectorQuery); if (!el) return; el.setFocus(); QMouseEvent pressEvent(QMouseEvent::MouseButtonPress, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this, &pressEvent); QMouseEvent releaseEvent(QMouseEvent::MouseButtonRelease, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this, &releaseEvent); } And you call it as so: myWebView->click("a[href]"); // will click first link on page myWebView->click("input[type=submit]"); // submits a form THE ONLY PROBLEM IS: if the element is not visible in the window, it is impossible to click. What I mean is if you have to scroll down to see it, you can't click it. I imagine this has to do with the geometry, since the element doesn't show up on the screen it can't do the math to click it right. Any ideas to get around this? Maybe some way to make the window behave like a billion x billion pixels but still look 200x200?

  • Fact or fiction: Webkit’s rendering performance is much lower when used in Qt

    - by Jen
    Using Qt’s Webkit implementation renders much slower than directly implementing the Webkit engine -- is this true or just a myth? From my own experience, I found the load time of a complex page about twice as long in Qt’s “Fancy Browser” example as it does in Google Chrome (which also incorporates a port of Webkit), but I hardly think that is a fair comparison. Any insights on this?
