Detailed Description

WebEngineProfile contains settings, scripts, and the list of visited links shared by all views that belong to the profile. As such, profiles can be used to isolate views from each other. A typical use case is a dedicated profile for a 'private browsing' mode.

Each web engine view has an associated profile. Views that do not have a specific profile set share a common default one.

Property Documentation

cachePath : string

The path to the location where the profile's caches are stored, in particular the HTTP cache.

By default, the caches are stored below QStandardPaths::writableLocation(QStandardPaths::CacheLocation) in a directory named using storageName.


httpAcceptLanguage : string

The value of the Accept-Language HTTP request-header field.

This QML property was introduced in QtWebEngine 1.2.


httpCacheMaximumSize : int

The maximum size of the HTTP cache. If 0, the size will be controlled automatically by QtWebEngine. The default value is 0.

See also httpCacheType.


httpCacheType : enumeration

This enumeration describes the type of the HTTP cache:

ConstantDescription
WebEngineProfile.MemoryHttpCacheUses an in-memory cache. This is the only setting possible if offTheRecord is set or no persistentStoragePath is available.
WebEngineProfile.DiskHttpCacheUses a disk cache. This is the default value.

httpUserAgent : string

The user-agent string sent with HTTP to identify the browser.


offTheRecord : bool

Whether the web engine profile is off-the-record. An off-the-record profile forces cookies, the HTTP cache, and other normally persistent data to be stored only in memory.


persistentCookiesPolicy : enumeration

This enumeration describes the policy of cookie persistency:

ConstantDescription
WebEngineProfile.NoPersistentCookiesBoth session and persistent cookies are stored in memory. This is the only setting possible if offTheRecord is set or no persistentStoragePath is available.
WebEngineProfile.AllowPersistentCookiesCookies marked persistent are saved to and restored from disk, whereas session cookies are only stored to disk for crash recovery. This is the default setting.
WebEngineProfile.ForcePersistentCookiesBoth session and persistent cookies are saved to and restored from disk.

persistentStoragePath : string

The path to the location where the persistent data for the browser and web content are stored. Persistent data includes persistent cookies, HTML5 local storage, and visited links.

By default, the storage is located below QStandardPaths::writableLocation(QStandardPaths::DataLocation) in a directory named using storageName.


storageName : string

The storage name that is used to create separate subdirectories for each profile that uses the disk for storing persistent data and cache.

See also WebEngineProfile::persistentStoragePath and WebEngineProfile::cachePath.
