CefSettings Class

Initializes a new instance of the CefSettings class

Comma delimited ordered list of language codes without any whitespace that will be used in the "Accept-Language" HTTP header. May be overridden on a per-browser basis using the CefBrowserSettings.accept_language_list value. If both values are empty then "en-US,en" will be used. Can be overridden for individual CefRequestContext instances via the CefRequestContextSettings.accept_language_list value.

Opaque background color used for accelerated content. By default the background color will be white. Only the RGB compontents of the specified value will be used. The alpha component must greater than 0 to enable use of the background color but will be otherwise ignored.

The path to a separate executable that will be launched for sub-processes. By default the browser process executable is used. See the comments on CefExecuteProcess() for details. Also configurable using the "browser-subprocess-path" command-line switch.

The location where cache data will be stored on disk. If empty then browsers will be created in "incognito mode" where in-memory caches are used for storage and no data is persisted to disk. HTML5 databases such as localStorage will only persist across sessions if a cache path is specified. Can be overridden for individual CefRequestContext instances via the CefRequestContextSettings.cache_path value.

Set to true to disable configuration of browser process features using standard CEF and Chromium command-line arguments. Configuration can still be specified using CEF data structures or via the CefApp::OnBeforeCommandLineProcessing() method.

By default CEF V8 references will be invalidated (the IsValid() method will return false) after the owning context has been released. This reduces the need for external record keeping and avoids crashes due to the use of V8 references after the associated context has been released. CEF currently offers two context safety implementations with different performance characteristics. The default implementation (value of 0) uses a map of hash values and should provide better performance in situations with a small number contexts. The alternate implementation (value of 1) uses a hidden value attached to each context and should provide better performance in situations with a large number of contexts. If you need better performance in the creation of V8 references and you plan to manually track context lifespan you can disable context safety by specifying a value of -1. Also configurable using the "context-safety-implementation" command-line switch.

Set to true to control browser process main (UI) thread message pump scheduling via the CefBrowserProcessHandler::OnScheduleMessagePumpWork() callback. This option is recommended for use in combination with the CefDoMessageLoopWork() function in cases where the CEF message loop must be integrated into an existing application message loop (see additional comments and warnings on CefDoMessageLoopWork). Enabling this option is not recommended for most users; leave this option disabled and use either the CefRunMessageLoop() function or multi_threaded_message_loop if possible.

Set to true (1) to ignore errors related to invalid SSL certificates. Enabling this setting can lead to potential security vulnerabilities like "man in the middle" attacks. Applications that load content from the internet should not enable this setting. Also configurable using the "ignore-certificate-errors" command-line switch. Can be overridden for individual CefRequestContext instances via the CefRequestContextSettings.ignore_certificate_errors value.

Custom flags that will be used when initializing the V8 JavaScript engine. The consequences of using custom flags may not be well tested. Also configurable using the "js-flags" command-line switch.

The locale string that will be passed to WebKit. If empty the default locale of "en-US" will be used. This value is ignored on Linux where locale is determined using environment variable parsing with the precedence order: LANGUAGE, LC_ALL, LC_MESSAGES and LANG. Also configurable using the "lang" command-line switch.

The fully qualified path for the locales directory. If this value is empty the locales directory must be located in the module directory. This value is ignored on Mac OS X where pack files are always loaded from the app bundle resource directory. Also configurable using the "locales-dir-path" command-line switch.

The directory and file name to use for the debug log. If empty a default log file name and location will be used. On Windows and Linux a "debug.log" file will be written in the main executable directory. On Mac OS X a "~/Library/Logs/[app name]_debug.log" file will be written where [app name] is the name of the main app executable. Also configurable using the "log-file" command-line switch.

The log severity. Only messages of this severity level or higher will be logged. Also configurable using the "log-severity" command-line switch with a value of "verbose", "info", "warning", "error", "error-report" or "disable".

Set to true to have the browser process message loop run in a separate thread. If false than the CefDoMessageLoopWork() function must be called from your application message loop. This option is only supported on Windows.

Set to true to disable the sandbox for sub-processes. See cef_sandbox_win.h for requirements to enable the sandbox on Windows. Also configurable using the "no-sandbox" command-line switch.

Set to true to disable loading of pack files for resources and locales. A resource bundle handler must be provided for the browser and render processes via CefApp::GetResourceBundleHandler() if loading of pack files is disabled. Also configurable using the "disable-pack-loading" command- line switch.

To persist session cookies (cookies without an expiry date or validity interval) by default when using the global cookie manager set this value to true. Session cookies are generally intended to be transient and most Web browsers do not persist them. A |cache_path| value must also be specified to enable this feature. Also configurable using the "persist-session-cookies" command-line switch. Can be overridden for individual CefRequestContext instances via the CefRequestContextSettings.persist_session_cookies value.

To persist user preferences as a JSON file in the cache path directory set this value to true. A |cache_path| value must also be specified to enable this feature. Also configurable using the "persist-user-preferences" command-line switch. Can be overridden for individual CefRequestContext instances via the CefRequestContextSettings.persist_user_preferences value.

Value that will be inserted as the product portion of the default User-Agent string. If empty the Chromium product version will be used. If |userAgent| is specified this value will be ignored. Also configurable using the "product-version" command-line switch.

Set to a value between 1024 and 65535 to enable remote debugging on the specified port. For example, if 8080 is specified the remote debugging URL will be http://localhost:8080. CEF can be remotely debugged from any CEF or Chrome browser window. Also configurable using the "remote-debugging-port" command-line switch.

The fully qualified path for the resources directory. If this value is empty the cef.pak and/or devtools_resources.pak files must be located in the module directory on Windows/Linux or the app bundle Resources directory on Mac OS X. Also configurable using the "resources-dir-path" command-line switch.

Set to true to use a single process for the browser and renderer. This run mode is not officially supported by Chromium and is less stable than the multi-process default. Also configurable using the "single-process" command-line switch.

The number of stack trace frames to capture for uncaught exceptions. Specify a positive value to enable the CefV8ContextHandler:: OnUncaughtException() callback. Specify 0 (default value) and OnUncaughtException() will not be called. Also configurable using the "uncaught-exception-stack-size" command-line switch.

Value that will be returned as the User-Agent HTTP header. If empty the default User-Agent string will be used. Also configurable using the "user-agent" command-line switch.

The location where user data such as spell checking dictionary files will be stored on disk. If empty then the default platform-specific user data directory will be used ("~/.cef_user_data" directory on Linux, "~/Library/Application Support/CEF/User Data" directory on Mac OS X, "Local Settings\Application Data\CEF\User Data" directory under the user profile directory on Windows).

Set to true (1) to enable windowless (off-screen) rendering support. Do not enable this value if the application does not use windowless rendering as it may reduce rendering performance on some systems.

Serves as the default hash function.

Gets the Type of the current instance.

Returns a string that represents the current object.

Calls the object method by name.

Gets the value of the object property by name.

Gets the value of the object property by name.
