Detailed Description

Manage access to preferences.

Many built-in preferences are registered by Chromium. Custom preferences can be registered in CefBrowserProcessHandler::OnRegisterCustomPreferences.

Member Function Documentation

◆ CanSetPreference()

virtual bool CefPreferenceManager::CanSetPreference ( const CefString name)
pure virtual

Returns true if the preference with the specified |name| can be modified using SetPreference.

As one example preferences set via the command-line usually cannot be modified. This method must be called on the browser process UI thread.

◆ GetAllPreferences()

virtual CefRefPtr<CefDictionaryValue> CefPreferenceManager::GetAllPreferences ( bool  include_defaults)
pure virtual

Returns all preferences as a dictionary.

If |include_defaults| is true then preferences currently at their default value will be included. The returned object contains a copy of the underlying preference values and modifications to the returned object will not modify the underlying preference values. This method must be called on the browser process UI thread.

◆ GetGlobalPreferenceManager()

static CefRefPtr<CefPreferenceManager> CefPreferenceManager::GetGlobalPreferenceManager ( )
static

Returns the global preference manager object.

◆ GetPreference()

virtual CefRefPtr<CefValue> CefPreferenceManager::GetPreference ( const CefString name)
pure virtual

Returns the value for the preference with the specified |name|.

Returns NULL if the preference does not exist. The returned object contains a copy of the underlying preference value and modifications to the returned object will not modify the underlying preference value. This method must be called on the browser process UI thread.

◆ HasPreference()

virtual bool CefPreferenceManager::HasPreference ( const CefString name)
pure virtual

Returns true if a preference with the specified |name| exists.

This method must be called on the browser process UI thread.

◆ SetPreference()

virtual bool CefPreferenceManager::SetPreference ( const CefString name,
CefRefPtr< CefValue value,
CefString error 
)
pure virtual

Set the |value| associated with preference |name|.

Returns true if the value is set successfully and false otherwise. If |value| is NULL the preference will be restored to its default value. If setting the preference fails then |error| will be populated with a detailed description of the problem. This method must be called on the browser process UI thread.
