QQmlPropertyCache: QQuickItem has FastProperty class info, but has not installed property accessors

286 views Asked by At

Built Raspberry Pi 2 linux distro including Qt5.4 + QtWebKit + QML plugin using Yocto on fido branch See tutorial

Testing with the following QML script

root@raspberrypi2:~# more webkit.qml
import QtWebKit 3.0

WebView {
    url: "http://www.nokia.com"
    preferredWidth: 490
    preferredHeight: 400
    scale: 0.5
    smooth: false
}

When running this script I am getting the following error:

root@raspberrypi2:~# /usr/bin/qt5/qmlscene --platform eglfs webkit.qml 
Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
QQmlPropertyCache: QQuickItem has FastProperty class info, but has not installed property accessors

Any pointers?

I had the same problem. The solution was to add the line

import QtQuick 2.0

to the QML file.
