<p>Provides an opportunity to register custom preferences prior to global and request context initialization.
|
|
|
|
<p>If |type| is CEF_PREFERENCES_TYPE_GLOBAL the registered preferences can be accessed via ICefPreferenceManager.GetGlobalPreferences after OnContextInitialized is called. Global preferences are registered a single time at application startup. See related TCefSettings.cache_path and TCefSettings.persist_user_preferences configuration.
|
|
|
|
<p>If |type| is CEF_PREFERENCES_TYPE_REQUEST_CONTEXT the preferences can be accessed via the ICefRequestContext after ICefRequestContextHandler.OnRequestContextInitialized is called. Request context preferences are registered each time a new ICefRequestContext is created. It is intended but not required that all request contexts have the same registered preferences. See related TCefRequestContextSettings.cache_path and TCefRequestContextSettings.persist_user_preferences configuration.

<p>Do not keep a reference to the |registrar| object. This function is called on the browser process UI thread.

<p>Implement this function to provide app-specific behavior when an already running app is relaunched with the same TCefSettings.root_cache_path value. For example, activate an existing app window or create a new app window. |command_line| will be read-only. Do not keep a reference to |command_line| outside of this function. Return true (1) if the relaunch is handled or false (0) for default relaunch behavior. Default behavior will create a new default styled Chrome window.
|
|
|
|
<p>To avoid cache corruption only a single app instance is allowed to run for a given TCefSettings.root_cache_path value. On relaunch the app checks a process singleton lock and then forwards the new launch arguments to the already running app process before exiting early. Client apps should therefore check the cef_initialize() return value for early exit before proceeding.
|
|
|
|
<p>This function will be called on the browser process UI thread.

Called from any thread when work has been scheduled for the browser process main (UI) thread. This callback is used in combination with TCefSettings.external_message_pump and GlobalCEFApp.DoMessageLoopWork in cases where the CEF message loop must be integrated into an existing application message loop (see additional comments and warnings on GlobalCEFApp.DoMessageLoopWork). This callback should schedule a GlobalCEFApp.DoMessageLoopWork call to happen on the main (UI) thread. |delay_ms| is the requested delay in milliseconds. If |delay_ms| is <= 0 then the call should happen reasonably soon. If |delay_ms| is > 0 then the call should be scheduled to happen after the specified delay and any currently pending scheduled call should be cancelled. </p>
