[webkit-qt] prevent mainframe from scrolling

[Felipe Crochik]

Just created a small sample project:
source: http://www.crochik.com/webkit/webviewbug.zip
deb for harmattan: http://www.crochik.com/webview/webviewbug_0.0.1_armel.deb

The qml page is really simple:

import QtQuick 1.1

import com.nokia.meego 1.0

import QtWebKit 1.0

PageStackWindow {

    id: window

    initialPage: mainPage;

    Page {

        id: mainPage

        Flickable {

                contentWidth: 500

                contentHeight: 500

                interactive: true

            WebView {

                width: 400

                height: 400

                anchors.centerIn: parent

                url: "http://www.crochik.com/webkit/scroll.html"

            }

        }

    }

}



Thanks,
Felipe
