QML WebView组件尚未准备好

Question

main.qml：

ApplicationWindow {
  visible: true
  visibility: "Maximized"
  title: "My title"

  WebView {
    id: webView
    objectName: "webView"
    anchors.fill: parent
    url: initialUrl
  }
}

main.cpp：

QQmlApplicationEngine engine;
QQmlContext *context = engine.rootContext();
context->setContextProperty(QString("initialUrl"), "http://google.com/");

QQmlComponent component(&engine, QUrl("qrc:/qml/main.qml"));
qDebug() << component.status();
component.create();

它是在Linux和Android上工作的，但是在Windows上我有这样的错误：

warning: QQmlComponent::Status(Ready) // This "qDebug() << component.status();" from my code

warning: QQmlComponent: Component is not ready
warning: QObject::connect: invalid null parameter
warning: QObject::connect: invalid null parameter

怎么修呢？QT5.7.0 (msvc 2015编译器)

解决方案：

不要使用windeployqt。

安装QT5.7 for Windows。使用Process和手动复制依赖项。
