I have added view->page()->settings()->setAttribute(QWebSettings::PluginsEnabled,true);

but still no luck even with gnash

even if seems that is opened if you trace it with strace

stat(“/usr/lib/gnash/libgnashplugin.so”, {st_mode=S_IFREG|0644, st_size=57592, …}) = 0
open(“/usr/lib/gnash/libgnashplugin.so”, O_RDONLY) = 12

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

You need xvfb! not a full blown Xserver.
For the compilation, qmake is able to regenerate the configuration so you shouldn’t need to do anything by hand either, if you have all the libs. Well in theory. Maybe a problem in your distribution/installation, i don’t know.

For the includes, wordpress strip em out so i don’t know either which ones are involved maybe you use a different version of QT.

Finally about Flash, i don’t know either if that works. if it renders through QT somehow, that should work out. Using an open source flash plugin probably works (you only need the still image anyway)
Good luck

And when running this app, you still need X server:

./wkthumb http://google.com google.png
wkthumb: cannot connect to X server

After 5 minutes of trying to compile this, I came into the following:

* change each #include to #include
* replace #include with these includes:

#include
#include
#include

* compile the program with the following command:

g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4 -I/usr/include/qt4/QtWebKit -I. -I. -I. -o wkthumb.o wkthumb.cpp

* link the program with the following command:

g++ -Wl,-O1 -o wkthumb wkthumb.o -L/usr/lib -lQtGui -lQtCore -lQtWebKit -lpthread

I’m not sure how to port these compile&link instructions to qmake (probably some changes to wkthumb.pro are needed).

Quick (damn short!) and elegant. Moreover, exactly what I need right now. I’ve used webscreenie with mentioned Xfvb, but this was not elegant.

Will this script render external objects like Flash? It seems that the only way to get screenshots with Flash is to use a full blown XServer. Has anybody been able to do this without the XServer on Linux (or even better, Ubuntu 9.04)?
