[Qt-interest] QWebPage in a thread

[Jason H]

You might actually be able to do this. 

QWebPage and its like are only derived from QObject. You'd have to create the painter for the system from a QPixmap, which is owned by the read. You can then emit the pixmap(s) when you are done and display them. 

I beleive the limitation is that you cannot access the screen (the paint device for it) from another thread. 

I think this topic came up a few months ago on this list, search on QWebPage...

Subject: [Qt-interest] QWebPage in a thread

 
Hi, does anyone have experience using QWebPage in a threaded environment? 

Currently I'm loading HTML-content into a QWebPage and rendering parts of it to QPixmaps using QWebFrame's render-function. I would like to make this threaded since it takes some time especially with large HTML-pages. I'm wondering if this is possible or if anyone has a better way of doing this? 

Am I right assuming that a QWebPage can't be created outside the GUI-thread? 

PS. What I'm essentially doing is pagination of html-content.
