详细描述

WebView is a component for displaying web content which is implemented using native APIs on the platforms where this is available, thus it does not necessarily require including a full web browser stack as part of the application.

To make the Qt WebView module function correctly across all platforms, it is necessary to call QtWebView::initialize () right after creating the QGuiApplication 实例。

注意： Due to platform limitations overlapping the WebView and other QML components is not supported.

[read-only] title : string

The title of the currently loaded web page.

url : url

信号文档编制

cookieAdded ( string domain , string name )

This signal is emitted when a cookie is added.

The parameters provide information about the domain 和 name of the added cookie.

注意： When Qt WebEngine module is used as backend, cookieAdded signal will be emitted for any cookie added to the underlying QWebEngineCookieStore , including those added by websites. In other cases cookieAdded signal is only emitted for cookies explicitly added with setCookie ().

注意： 相应处理程序是 onCookieAdded .

cookieRemoved ( string domain , string name )

This signal is emitted when a cookie is deleted.

The parameters provide information about the domain 和 name of the deleted cookie.

注意： 相应处理程序是 onCookieRemoved .

loadingChanged ( WebViewLoadRequest loadRequest )

This signal is emitted when the state of loading the web content changes. By handling this signal it's possible, for example, to react to page load errors.

The loadRequest parameter holds the url and status of the request, as well as an errorString containing an error message for a failed request.

注意： 相应处理程序是 onLoadingChanged .
