Question

main.qml：

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

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

main.cpp中：

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();

它适用于Linux和Android，但在Windows上我有这个错误：

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

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

解决方案：

请勿使用windeployqt。

为Windows安装Qt 5.7。使用Process Explorer和手动复制依赖项。

QML WebView组件尚未就绪
