It works well for most other pages. This is my codes in QtWebKit(r50477 + Qt4.6.0 + GCC4.4.0). // set the viewport size to the whole webpage size m_webview->page()->setViewportSize ( tmpSize ); //disable scrollbar m_webview->page()->mainFrame()->setScrollBarPolicy(Qt::Horizontal,Qt::ScrollBarAlwaysOff); m_webview->page()->mainFrame()->setScrollBarPolicy(Qt::Vertical,Qt::ScrollBarAlwaysOff); //paint webpage into image QImage im ( tmpSize , QImage::Format_RGB888); //QImage::Format_RGB32 QPainter painter ( & im ); m_webview->page()->mainFrame()->render ( & painter ); The tree i have tracked: .....QWebFramePrivate::renderPrivate(QPainter *painter, QWebFrame::RenderLayer layer, const QRegion &clip) ...........WebCore::FrameView::paintContents(GraphicsContext* p, const IntRect& rect) ................contentRenderer->layer()->paint(p, rect, m_paintRestriction, eltRenderer); //void RenderLayer::paint ......................void RenderLayer::paintLayer(....) ...........................void RenderBlock::paint(PaintInfo& paintInfo, int tx, int ty) ...............................void RenderBlock::paintObject(PaintInfo& paintInfo, int tx, int ty) ....................................paintBoxDecorations(paintInfo, tx, ty); //hang here now.... I am not familiar with the WebKit rendering codes. It is too hard for me now. Please help to fix this bug. Thanks. 174856 1 tiansjun 2009-12-25 02:36:19 -0800 Safari 4.0.4 for Win hangs(or load OK but hangs while refreshing) while loading this page. Arora 0.10.0 and Chrome 4.0.0249.30 finish loading soon. 174859 2 tiansjun 2009-12-25 03:58:02 -0800 Sorry, it seems a bug of Qt 4.6. Program hangs on QPainter::fillRect while invoking GraphicsContext::fillRect(FloatRect(0, 0, 1019, 44364), Color(-1))); Any one can help to report this bug to Qt community? Thanks.
