import 语句: | import QtWebView 1.15 |
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.

The URL of currently loaded web page. Changing this will trigger loading new content.
The URL is used as-is. URLs that originate from user input should be parsed with QUrl::fromUserInput() .
注意: The WebView does not support loading content through the Qt Resource system.
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.

加载指定 html content to the web view.

, which is the base URL, then an image referenced with the relative url,
diagram.png
,应该在
http://www.example.com/documents/diagram.png
.
注意: The WebView does not support loading content through the Qt Resource system.
