QWebEngineSettings::DisallowUnknownUrlSchemes

1

Disallows all navigation requests to URLs with unknown schemes.

QWebEngineSettings::AllowUnknownUrlSchemesFromUserInteraction

Allows navigation requests to URLs with unknown schemes that are issued from user-interaction (like a mouse-click), whereas other navigation requests (for example from JavaScript) are suppressed.

QWebEngineSettings::AllowAllUnknownUrlSchemes

3

Allows all navigation requests to URLs with unknown schemes.

QWebEngineSettings::AutoLoadImages

0

Automatically dowloads images for web pages. When this setting is disabled, images are loaded from the cache. Enabled by default.

QWebEngineSettings::JavascriptEnabled

1

Enables the running of JavaScript programs in the MainWorld. Enabled by default.

QWebEngineSettings::JavascriptCanOpenWindows

2

Allows JavaScript programs to open popup windows without user interaction. Enabled by default.

QWebEngineSettings::JavascriptCanAccessClipboard

3

Allows JavaScript programs to read from and write to the clipboard. Writing to the clipboard is always allowed if it is specifically requested by the user. See JavascriptCanPaste to also allow pasting the content of the clipboard content from JavaScript. Disabled by default.

QWebEngineSettings::LinksIncludedInFocusChain

4

Includes hyperlinks in the keyboard focus chain. Enabled by default.

QWebEngineSettings::LocalStorageEnabled

5

Enables support for the HTML 5 local storage feature. Enabled by default.

QWebEngineSettings::LocalContentCanAccessRemoteUrls

6

Allows locally loaded documents to ignore cross-origin rules so that they can access remote resources that would normally be blocked, because all remote resources are considered cross-origin for a local file. Remote access that would not be blocked by cross-origin rules is still possible when this setting is disabled (default). Note that disabling this setting does not stop XMLHttpRequests or media elements in local files from accessing remote content. Basically, it only stops some HTML subresources, such as scripts, and therefore disabling this setting is not a safety mechanism.

QWebEngineSettings::XSSAuditingEnabled

7

Monitors load requests for cross-site scripting attempts. Suspicious scripts are blocked and reported in the inspector's JavaScript console. Enabled by default.

QWebEngineSettings::SpatialNavigationEnabled

8

Enables the Spatial Navigation feature, which means the ability to navigate between focusable elements, such as hyperlinks and form controls, on a web page by using the Left, Right, Up and Down arrow keys. For example, if a user presses the Right key, heuristics determine whether there is an element they might be trying to reach towards the right and which element they probably want. Disabled by default.

QWebEngineSettings::LocalContentCanAccessFileUrls

9

Allows locally loaded documents to access other local URLs. Enabled by default.

QWebEngineSettings::HyperlinkAuditingEnabled

10

Enables support for the ping attribute for hyperlinks. Disabled by default.

QWebEngineSettings::ScrollAnimatorEnabled

11

Enables animated scrolling. Disabled by default.

QWebEngineSettings::ErrorPageEnabled

12

Enables displaying the built-in error pages of Chromium. Enabled by default.

QWebEngineSettings::PluginsEnabled

13

Enables support for Pepper plugins, such as the Flash player. Disabled by default. See also Pepper Plugin API. (Added in Qt 5.6)

QWebEngineSettings::FullScreenSupportEnabled

14

QWebEngineSettings::ScreenCaptureEnabled

16

Enables support for HTML 5 WebGL. Enabled by default if available. (Added in Qt 5.7)

QWebEngineSettings::Accelerated2dCanvasEnabled

17

Specifies whether the HTML5 2D canvas should be a OpenGL framebuffer. This makes many painting operations faster, but slows down pixel access. Enabled by default if available. (Added in Qt 5.7)

QWebEngineSettings::AutoLoadIconsForPage

18

Automatically downloads icons for web pages. Enabled by default. (Added in Qt 5.7)

QWebEngineSettings::TouchIconsEnabled

19

Enables support for touch icons and precomposed touch icons Disabled by default. (Added in Qt 5.7)

QWebEngineSettings::FocusOnNavigationEnabled

20

Gives focus to the view associated with the page, whenever a navigation operation occurs (load, stop, reload, reload and bypass cache, forward, backward, set content, and so on). Disabled by default. (Added in Qt 5.8)

QWebEngineSettings::PrintElementBackgrounds

21

Turns on printing of CSS backgrounds when printing a web page. Enabled by default. (Added in Qt 5.8)

QWebEngineSettings::AllowRunningInsecureContent

22

By default, HTTPS pages cannot run JavaScript, CSS, plugins or web-sockets from HTTP URLs. This provides an override to get the old insecure behavior. Disabled by default. (Added in Qt 5.8)

QWebEngineSettings::AllowGeolocationOnInsecureOrigins

23

Since Qt 5.7, only secure origins such as HTTPS have been able to request Geolocation features. This provides an override to allow non secure origins to access Geolocation again. Disabled by default. (Added in Qt 5.9)

QWebEngineSettings::AllowWindowActivationFromJavaScript

24

Allows activating windows by using the window.focus() JavaScript method. Disabled by default. (Added in Qt 5.10)

25

Shows scroll bars. Enabled by default. (Added in Qt 5.10)

QWebEngineSettings::PlaybackRequiresUserGesture

26

Inhibits playback of media content until the user interacts with the page. This is similar to how Chrome on Android behaves, while the default behavior when it is disabled is similar to Chrome on desktops. (Added in Qt 5.11)

QWebEngineSettings::JavascriptCanPaste

28

Enables JavaScript execCommand("paste"). This also requires enabling JavascriptCanAccessClipboard. Disabled by default. (Added in Qt 5.11)

QWebEngineSettings::WebRTCPublicInterfacesOnly

27

Limits WebRTC to public IP addresses only. When disabled WebRTC may also use local network IP addresses, but remote hosts can also see your local network IP address. Disabled by default. (Added in Qt 5.11)
