Detailed Description

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 instance.

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

Property Documentation

[read-only] canGoBack : bool

Holds true if it's currently possible to navigate back in the web history.


[read-only] canGoForward : bool

Holds true if it's currently possible to navigate forward in the web history.


[read-only] loadProgress : int

The current load progress of the web content, represented as an integer between 0 and 100.


[read-only] loading : bool

Holds true if the WebView is currently in the process of loading new content, false otherwise.

See also loadingChanged().


[read-only] title : string

The title of the currently loaded web page.


url : url

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().

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


Signal Documentation

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.

See also WebViewLoadRequest.


Method Documentation

void goBack()

Navigates back in the web history.


void goForward()

Navigates forward in the web history.


void loadHtml(string html, url baseUrl)

Loads the specified 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 is retrieved from http://www.example.com/documents/overview.html, which is the base URL, then an image referenced with the relative url, diagram.png, should be at http://www.example.com/documents/diagram.png.

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

See also url.


void reload()

Reloads the current 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()

Stops loading the current url.
