[Qt-interest] Printing a (local) webpage with images

[Mathias Waack]

QTextDocument could be a solution, thanks Jason. It doesn't work for us 
because we're using some css features not supported there. 
We've solved this issue by creating a dialog containing the QWebView. If we 
print the QWebview from this dialog (in a slot connected to loadFinished) it 
works fine. Its an ugly workaround but it works for us.

PS: I consider this an ugly workaround because I assume we've just "solved" 
the async-load-problem by spending more time in the event loop. So the main 
question remains: how can I check whether an external object is loaded?
