How to find out why QML WebView page loading fails

I try to open a local page (WebOS app) using QML WebView

import QtQuick 1.1
import QtWebKit 1.0
import com.nokia.meego 1.0

Page 
{
    id: mainPage
    Flickable
    {
        id: appFlickable
        anchors.fill: parent
        clip: true

        contentHeight: appView.height
        contentWidth: appView.width

        WebView
        {
            id: appView
            preferredHeight: parent.height
            preferredWidth: parent.width
            url: appUrl
            settings.javascriptCanOpenWindows: true
            settings.javascriptEnabled: true
            settings.autoLoadImages: true
            settings.javascriptCanAccessClipboard: true
            settings.developerExtrasEnabled: true
            onLoadFailed: console.log("load failed")
            onLoadFinished: console.log("load finished")
        }
    }
}

I load it in main.cpp this way:

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QDeclarativeView view;
    view.rootContext()->setContextProperty("appUrl", argv[1]);
    view.setSource(QUrl("qrc:/qml/main.qml"));
    view.showFullScreen();
    return app.exec();
}

I'm always getting a load fail. Is there any way I can find out the problem, enable some web console to show me what fails.

Thanks

Marcin

Most likely WebView::onLoadFailed called on network errors (unreachable or invalid url etc.).

What you can try to do, is to listen to NetworkAccessManager's finished signal to check network reply for error.

connect (viewer.engine()->networkAccessManager(), SIGNAL(finished(QNetworkReply*)),
         logger, SLOT(onNetworkRequestFinished(QNetworkReply*)));

Where logger is a QObject with onNetworkRequestFinished slot. 

void Logger::onNetworkRequestFinished(QNetworkReply* reply)
{
    if (reply->error() != QNetworkReply::NoError) {
        qDebug() << "network error:" << reply->errorString();
    }
    reply->deleteLater();
}

For details refer to QNetworkReply documentation.
