QGraphicsWebView rendering webpage issue

Yugan

Hi Guys,

I tried to render webpage using QGraphicsWebView here.

Page is rendering but some how text is not rendered correctly. Am using QT 5, is it problem in QT 5 becoz above is perfectly rendering using QT 4.7 or am i missing any thing that hampers text rendering in webpage.

Below the handling code

@ scene = new QGraphicsScene(ui->graphicsView);

ui->graphicsView->setScene(scene);
ui->graphicsView->setAttribute(Qt::WA_OpaquePaintEvent);

webView = new  QGraphicsWebView;
webView->setPalette(QApplication::palette("QWebView"));
webView->page()->setPalette(QApplication::palette("QWebPage"));

scene->addItem(webView);

glWid = new QGLWidget();

ui->graphicsView->setViewport(glWid);
ui->graphicsView->setViewportUpdateMode(QGraphicsView::FullViewportUpdate);

ui->graphicsView->setOptimizationFlags(QGraphicsView::DontSavePainterState);


QWebSettings *settings = QWebSettings::globalSettings();
settings->setAttribute(QWebSettings::JavascriptEnabled, true);

mainpage = new WebPage(this);
webView->setPage(mainpage);

webView->page()->mainFrame()->setScrollBarPolicy(Qt::Vertical, Qt::ScrollBarAlwaysOn);
webView->page()->mainFrame()->setScrollBarPolicy(Qt::Horizontal, Qt::ScrollBarAlwaysOff);

webView->resize(1024, 768);

webView->settings()->setAttribute(QWebSettings::PluginsEnabled, true);

webView->page()->settings()->setAttribute(QWebSettings::AcceleratedCompositingEnabled,true);
webView->page()->settings()->setAttribute(QWebSettings::AutoLoadImages,true);
webView->page()->settings()->setAttribute(QWebSettings::JavascriptEnabled,true);
webView->page()->settings()->setAttribute(QWebSettings::JavascriptCanOpenWindows,true);

webView->page()->setLinkDelegationPolicy(QWebPage::DelegateAllLinks);
webView->page()->setForwardUnsupportedContent(true);

webView->setUrl(QUrl(QStringLiteral("http://www.google.co.in")));@

Able to solve the problem.

Removed following code in above. It rendered perfectly.
@ glWid = new QGLWidget();

ui->graphicsView->setViewport(glWid);
ui->graphicsView->setViewportUpdateMode(QGraphicsView::FullViewportUpdate);

ui->graphicsView->setOptimizationFlags(QGraphicsView::DontSavePainterState);@

Hope it help someone.....!!

@tushar Note that you may want to use QOpenGLWidget these days instead of QGLWidget
