[Interest] qtwebview with qtwebchannel

[Sylvain Pointeau]

Hello,

I finally succeeded to make it working on the simulator... *unfortunately
it does not work on the physical ipad.*

to make it working, I had to copy the resource files on the temp dir, to
pass the temp dir to QML, then use "file://"+mytemppath+"/index.html". Also
I removed all "qrc:/" in the html, and put manually the qwebchannel.js in
the qrc.

    QString tmploc =
QStandardPaths::writableLocation(QStandardPaths::TempLocation);

    QDir tmpdir(tmploc+"/");


    qDebug() << QFileInfo(tmpdir.absolutePath()).absoluteFilePath();


    QDirIterator it(":"/*, QDirIterator::Subdirectories*/);

    while (it.hasNext()) {

        QString tmpfile = it.next();

        QFileInfo file = QFileInfo(tmpdir.absolutePath() +
tmpfile.right(tmpfile.size()-1));

        QFile::remove(file.absoluteFilePath()); // remove previous
file to make sure we have the latest version

        QFile::copy(tmpfile, file.absoluteFilePath());

        qDebug() << tmpfile;

    }


.....


    QQmlApplicationEngine engine;


    QQmlContext *context = engine.rootContext();

    context->setContextProperty(QStringLiteral("mylocalpath"),
QFileInfo(tmpdir.absolutePath()).absoluteFilePath());


.....


and in QML:


            WebView {

                id: webView

                anchors.fill: parent

                anchors.margins: 5

                url: "file://"+mylocalpath+"/index.html"

                onLoadingChanged: {

                    if (loadRequest.errorString)

                        { console.error(loadRequest.errorString); }

                }

            }
