I have an application done in QML or with QGraphicsWebView . I need to be able to display a qml webview that display a unity3D plugin web page. for example : http://download.unity3d.com/gallery/live-demos It works fine if for example I enter this url in the Qt (C++) browser demo, but when I try to load this url in a qml webview or a QGraphicsWebView … I see only a black screen … and when I quit my apps I see a crash report from unity3D ( I display QML using opengl viewport). what can be different from a normal qwebview … I was thinking that it was an opengl issue … but if I launch the c++ browser demo with -graphicssystem opengl … It works fine, it’s only when it’s using in QML (for information I use Windows Seven platform). I don’t know what’s happen ! Here an easy trouble example : you need to download unity3D plugin in chrome before :(http://unity3d.com/webplayer/) #include <QtGui/QApplication> #include <QWebView> #include <QGraphicsView> #include <QGraphicsWebView> static const QUrl URL = QUrl("http://download.unity3d.com/gallery/live-demos"); static const int RESOLUTION_X = 1920; static const int RESOLUTION_Y = 1080; int main(int argc, char *argv[]) { QApplication a(argc, argv); QWebView * view = new QWebView; view->settings()->setAttribute(QWebSettings::PluginsEnabled, true); view->setUrl(URL); view->setFixedSize(RESOLUTION_X, RESOLUTION_Y); view->setWindowTitle("WebView"); view->show(); //--------------------------------------------------------------------------------------------- QGraphicsScene * scene = new QGraphicsScene(); QGraphicsView * graphicsView = new QGraphicsView(scene); QGraphicsWebView * graphicsWebView = new QGraphicsWebView; graphicsWebView->settings()->setAttribute(QWebSettings::PluginsEnabled, true); graphicsWebView->setUrl(URL); scene->addItem(graphicsWebView); scene->setSceneRect(QRect(0, 0, RESOLUTION_X, RESOLUTION_Y)); graphicsWebView->resize(RESOLUTION_X, RESOLUTION_Y); graphicsView->setFixedSize(RESOLUTION_X, RESOLUTION_Y); graphicsView->setWindowTitle("GraphicsWebView"); graphicsView->show(); return a.exec(); }
