I have modified the #include this way (add the greater and less then signs)
#include Qt
#include QtGui
#include QWebView
#include QWebFrame

and in wkthumb.pro i have added

QT += network script webkit
CONFIG += qt

all worked ok
the only issue i have now is with flash loading

[...] While a better solution would still be to bypass QT and render ‘by hand’ to and image file, or hack QT to do so (without requiring any X server connection, and using fewer dependency than large QT libraries…), I decided to run my script again, and I ran into troubles with python-qt4 on some debian systems (and older Fedora system, as a reader pointed out).

Maybe it is of interests of people on Fedora that fc9 packages you can find for PyQt4 (e.g: PyQt4-4.4.2-2.fc9.i386.rpm) do not have WebKit support and silently fail to run the script.

Installing PyQt4-4.4.3-1.fc10.i386.rpm and sip-4.7.7-3.fc10.i386.rpm (even if they are fc10 they installed smoothly on my fc9) fixed my problem and let me build thumbnails!

Thank you for the great post!

I tested it on windows (Python 2.5.2, PyQT 4.4.3) and it worked out of the box.

I did a few change:
self.web.setGeometry(0, 0, 800, 600); just after QWebView instantiation to make the default webport 800×600 instead of 640×480.

And changed thumb generation using the SmoothTransformation and cutting the result back to the requested size:
thumb = QImage(img.scaled(int(self.dim[0]), int(self.dim[1]), Qt.KeepAspectRatioByExpanding, Qt.SmoothTransformation).copy(0,0,int(self.dim[0]), int(self.dim[1])))

It’s way better now, but I have to understand why I can’t get it to work on my linux+Xvfb environment. Don’t even know where to start from

The page load is completed (I have logs for all the requests in the webserver). I also tried changing the connect to a different even like load started / progress but no way to see a call.

I use PyQt4-4.4.2, qt-4.4.1, qt-x11-4.4.1, sip-4.7.6, xorg-x11-server-Xvfb-1.4.99.901-29.20080415

Can I ask you what versions did you use?
