Possible to have web view on top of OpenGL widget.
I have a Qt application which uses a QGLWidget to start a window and load an openGL application. All drawing is done with pure OpenGL in this application right now.
I am hoping to figure out a way to integrate and overlay a Web view (of some sort) over the OpenGL context. Ideally I can just have the new widget be on top of the OpenGL context, but if that is not possible I suppose I could resize the OpenGL context (say to half the window width) and have the Web on the other half.
Anyways, I have tried the following, and all I got was a white screen (but strangely if I click and drag I can copy the correct text out).
QMainWindow window; QGraphicsView* viewp = new QGraphicsView(); window.setCentralWidget(viewp); window.show(); viewp->setScene(new QGraphicsScene(viewp)); MyGLWidget* gl = new MyGLWidget(); viewp->setViewport(gl); gl->show(); QGraphicsWebView web view; webview.load(QUrl("http://qt.io")); viewp->scene()->addItem(&webview);
If I don't add the QGraphicsWebView, then I do see the OpenGL context, but rendered terribly. To me this means that a GL widget cannot be drawn inside a QGraphicsView. I have looked around quite a bit for ways to do this and haven't come up with anything useful.
FYI, I am using Qt5.4 right now, and am willing to look at the 5.5 rc1 release. I also don't have a preference between QWebView and QWebEngine.
