詳細描述

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.

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

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

loadingChanged ( WebViewLoadRequest loadRequest )

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

void goBack ()

Navigates back in the web history.

void goForward ()

Navigates forward in the web history.

void loadHtml ( string html , url baseUrl )

加載指定 html content to the web view.

This method offers a lower-level alternative to the url property, which references HTML pages via URL.

External objects such as stylesheets or images referenced in the HTML document should be located relative to baseUrl . For example, if html 檢索自 http://www.example.com/documents/overview.html , which is the base URL, then an image referenced with the relative url, diagram.png ，應該在 http://www.example.com/documents/diagram.png .

注意： The WebView does not support loading content through the Qt Resource system.

另請參閱 url .

void reload ()

重新加載當前 url .

void runJavaScript ( string script , variant callback )

Runs the specified JavaScript. In case a callback function is provided, it will be invoked after the script finished running.

runJavaScript("document.title", function(result) { console.log(result); });

void stop ()

停止加載當前 url .
