  • Hi

    I am using Qt5.7 with QML WebEngine on Win10 x64. Following the above instructions I am still unable to play flash content. Could someone help ?


  • Hi

    I have found that when using in QML WebEngineView component, one should enable in QML the flash plugin as

    WebEngineView {
                        id: webView
                        anchors.fill: parent
                        url: "http://"
                        Component.onCompleted: {
                            //enable flash plugin
                            webView.settings.pluginsEnabled = true

    Otherwise the instructions above are correct.
