[Qt-interest] webkit with no GUI

[Benjamin]

Hi,

I have no idea if you can make Webkit work without a gui, but it seem that
the problem come from the call to QApplication::style(). You could try to
make a subclass of QApplication, overriding ::style() to return your own
QStyle.

Please respond if it works, I'm curious if webkit could work on the commande
line :-)

regards,
Benjamin
