Interface `ICefFrameHandler`

Implement this structure to handle events related to cef_frame_t life span. The order of callbacks is:

(1) During initial cef_browser_host_t creation and navigation of the main frame:

    - cef_frame_handler_t::OnFrameCreated => The initial main frame object has
      been created. Any commands will be queued until the frame is attached.
    - cef_frame_handler_t::OnMainFrameChanged => The initial main frame object
      has been assigned to the browser.
    - cef_life_span_handler_t::OnAfterCreated => The browser is now valid and
      can be used.
    - cef_frame_handler_t::OnFrameAttached => The initial main frame object is
      now connected to its peer in the renderer process. Commands can be routed.

(2) During further cef_browser_host_t navigation/loading of the main frame and/or sub-frames:

    - cef_frame_handler_t::OnFrameCreated => A new main frame or sub-frame
      object has been created. Any commands will be queued until the frame is
      attached.
    - cef_frame_handler_t::OnFrameAttached => A new main frame or sub-frame
      object is now connected to its peer in the renderer process. Commands can
      be routed.
    - cef_frame_handler_t::OnFrameDetached => An existing main frame or sub-
      frame object has lost its connection to the renderer process. If multiple
      objects are detached at the same time then notifications will be sent for
      any sub-frame objects before the main frame object. Commands can no longer
      be routed and will be discarded.
    - CefFremeHadler::OnFrameDestroyed => An existing main frame or sub-frame
      object has been destroyed.
    - cef_frame_handler_t::OnMainFrameChanged => A new main frame object has
      been assigned to the browser. This will only occur with cross-origin
      navigation or re-navigation after renderer process termination (due to
      crashes, etc).

(3) During final cef_browser_host_t destruction of the main frame:

    - cef_frame_handler_t::OnFrameDetached => Any sub-frame objects have lost
      their connection to the renderer process. Commands can no longer be routed
      and will be discarded.
    - CefFreameHandler::OnFrameDestroyed => Any sub-frame objects have been
      destroyed.
    - cef_life_span_handler_t::OnBeforeClose => The browser has been destroyed.
    - cef_frame_handler_t::OnFrameDetached => The main frame object have lost
      its connection to the renderer process. Notifications will be sent for any
      sub-frame objects before the main frame object. Commands can no longer be
      routed and will be discarded.
    - CefFreameHandler::OnFrameDestroyed => The main frame object has been
      destroyed.
    - cef_frame_handler_t::OnMainFrameChanged => The final main frame object has
      been removed from the browser.

Special handling applies for cross-origin loading on creation/navigation of sub-frames, and cross-origin loading on creation of new popup browsers. A temporary frame will first be created in the parent frame's renderer process. This temporary frame will never attach and will be discarded after the real cross-origin frame is created in the new/target renderer process. The client will receive creation callbacks for the temporary frame, followed by cross-origin navigation callbacks (2) for the transition from the temporary frame to the real frame. The temporary frame will not receive or execute commands during this transitional period (any sent commands will be discarded).

When the main frame navigates to a different origin the OnMainFrameChanged callback (2) will be executed with the old and new main frame objects.

Callbacks will not be executed for placeholders that may be created during pre-commit navigation for sub-frames that do not yet exist in the renderer process. Placeholders will have cef_frame_t::get_identifier() == -4.

The functions of this structure will be called on the UI thread unless otherwise indicated.

Interface `ICefv8ArrayBufferReleaseCallback` | Callback interface that is passed to ICefV8value.CreateArrayBuffer.
Interface `ICefv8Context` | Interface representing a V8 context handle. V8 handles can only be accessed from the thread on which they are created. Valid threads for creating a V8 handle include the render process main thread (TID_RENDERER) and WebWorker threads. A task runner for posting tasks on the associated thread can be retrieved via the ICefV8context.GetTaskRunner() function.
Interface `ICefv8Handler` | Interface that should be implemented to handle V8 function calls. The functions of this interface will be called on the thread associated with the V8 function.

Interface `ICefV8Interceptor`

Interface that should be implemented to handle V8 interceptor calls. The functions of this interface will be called on the thread associated with the V8 interceptor. Interceptor's named property handlers (with first argument of type CefString) are called when object is indexed by string. Indexed property handlers (with first argument of type int) are called when object is indexed by integer.

Interface `ICefV8Accessor` | Interface that should be implemented to handle V8 accessor calls. Accessor identifiers are registered by calling ICefV8value.SetValue(). The functions of this interface will be called on the thread associated with the V8 accessor.

Interface `ICefTask`

Implement this interface for asynchronous task execution. If the task is posted successfully and if the associated message loop is still running then the execute() function will be called on the target thread. If the task fails to post then the task object may be destroyed on the source thread instead of the target thread. For this reason be cautious when performing work in the task object destructor.

Interface `ICefTaskManager` | Interface that facilitates managing the browser-related tasks. The functions of this structure may only be called on the UI thread.

Interface `ICefTaskRunner`

Interface that asynchronously executes tasks on the associated thread. It is safe to call the functions of this interface on any thread.

CEF maintains multiple internal threads that are used for handling different types of tasks in different processes. The TCefThreadId definitions in cef_types.h list the common CEF threads. Task runners are also available for other CEF threads as appropriate (for example, V8 WebWorker threads).

Interface `ICefThread`

A simple thread abstraction that establishes a message loop on a new thread. The consumer uses ICefTaskRunner to execute code on the thread's message loop. The thread is terminated when the ICefThread object is destroyed or stop() is called. All pending tasks queued on the thread's message loop will run to completion before the thread is terminated. cef_thread_create() can be called on any valid CEF thread in either the browser or render process. This interface should only be used for tasks that require a dedicated thread. In most cases you can post tasks to an existing CEF thread instead of creating a new one; see cef_task.h for details.

Interface `ICefWaitableEvent`

WaitableEvent is a thread synchronization tool that allows one thread to wait for another thread to finish some work. This is equivalent to using a Lock+ConditionVariable to protect a simple boolean value. However, using WaitableEvent in conjunction with a Lock to wait for a more complex state change (e.g., for an item to be added to a queue) is not recommended. In that case consider using a ConditionVariable instead of a WaitableEvent. It is safe to create and/or signal a WaitableEvent from any thread. Blocking on a WaitableEvent by calling the *wait() functions is not allowed on the browser process UI or IO threads.

Interface `ICefv8Value` | Interface representing a V8 value handle. V8 handles can only be accessed from the thread on which they are created. Valid threads for creating a V8 handle include the render process main thread (TID_RENDERER) and WebWorker threads. A task runner for posting tasks on the associated thread can be retrieved via the ICefv8context.GetTaskRunner() function.
Interface `ICefV8StackFrame` | Interface representing a V8 stack frame handle. V8 handles can only be accessed from the thread on which they are created. Valid threads for creating a V8 handle include the render process main thread (TID_RENDERER) and WebWorker threads. A task runner for posting tasks on the associated thread can be retrieved via the ICefv8context.GetTaskRunner() function.
Interface `ICefV8StackTrace` | Interface representing a V8 stack trace handle. V8 handles can only be accessed from the thread on which they are created. Valid threads for creating a V8 handle include the render process main thread (TID_RENDERER) and WebWorker threads. A task runner for posting tasks on the associated thread can be retrieved via the ICefv8context.GetTaskRunner() function.

Interface `ICefDomNode` | Interface used to represent a DOM node. The functions of this interface should only be called on the render process main thread.
Interface `ICefDomDocument` | Interface used to represent a DOM document. The functions of this interface should only be called on the render process main thread thread.
Interface `ICefDomVisitor` | Interface to implement for visiting the DOM. The functions of this interface will be called on the render process main thread.
Interface `ICefCookieVisitor` | Interface to implement for visiting cookie values. The functions of this interface will always be called on the UI thread.

Interface `ICefCommandLine`

Interface used to create and/or parse command line arguments. Arguments with "–", "-" and, on Windows, "/" prefixes are considered switches. Switches will always precede any arguments without switch prefixes. Switches can optionally have a value specified using the "=" delimiter (e.g. "-switch=value"). An argument of "–" will terminate switch parsing with all subsequent tokens, regardless of prefix, being interpreted as non-switch arguments. Switch names should be lowercase ASCII and will be converted to such if necessary. Switch values will retain the original case and UTF8 encoding. This interface can be used before cef_initialize() is called.

Interface `ICefRequestContext`

A request context provides request handling for a set of related browser or URL request objects. A request context can be specified when creating a new browser via the ICefBrowserHost static factory functions or when creating a new URL request via the ICefUrlRequest static factory functions. Browser objects with different request contexts will never be hosted in the same render process. Browser objects with the same request context may or may not be hosted in the same render process depending on the process model. Browser objects created indirectly via the JavaScript window.open function or targeted links will share the same render process and the same request context as the source browser. When running in single-process mode there is only a single render process (the main process) and so all browsers created in single-process mode will share the same request context. This will be the first request context passed into a ICefBrowserHost static factory function and all other request context objects will be ignored.

See TCefSettings for additional options related to resource bundle loading. The functions of this interface may be called on any thread unless otherwise indicated.

Interface `ICefImage`

Container for a single image represented at different scale factors. All image representations should be the same size in density independent pixel (DIP) units. For example, if the image at scale factor 1.0 is 100x100 pixels then the image at scale factor 2.0 should be 200x200 pixels – both images will display with a DIP size of 100x100 units. The functions of this interface can be called on any browser process thread.

Interface `ICefMenuModelDelegate` | Implement this interface to handle menu model events. The functions of this interface will be called on the browser process UI thread unless otherwise indicated.
Interface `ICefServer` | Interface representing a server that supports HTTP and WebSocket requests. Server capacity is limited and is intended to handle only a small number of simultaneous connections (e.g. for communicating between applications on localhost). The functions of this interface are safe to call from any thread in the brower process unless otherwise indicated.

Interface `ICefServerHandler`

Implement this interface to handle HTTP server requests. A new thread will be created for each ICefServer.CreateServer call (the "dedicated server thread"), and the functions of this interface will be called on that thread. It is therefore recommended to use a different ICefServerHandler instance for each ICefServer.CreateServer call to avoid thread safety issues in the ICefServerHandler implementation.

Interface `ICefDisplay`

This interface typically, but not always, corresponds to a physical display connected to the system. A fake Display may exist on a headless system, or a Display may correspond to a remote, virtual display. All size and position values are in density independent pixel (DIP) coordinates unless otherwise indicated. Methods must be called on the browser process UI thread unless otherwise indicated.
