/// 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.
|
|
/// - 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).

/// their
|
|
/// connection to the renderer process. Commands can no longer be routed and

|
/// 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.
|
|
/// - cef_frame_handler_t::OnMainFrameChanged => The final main frame object has
|
|
/// been removed from the browser.
|
|
///
|
|
/// Cross-origin navigation and/or loading receives special handling.

///

/// When the main frame navigates to a different origin the OnMainFrameChanged
|

/// callback (2) will be executed with the old and new main frame objects.

///
|

/// When a new sub-frame is loaded in, or an existing sub-frame is navigated to,
|

/// a different origin from the parent frame, a temporary sub-frame object will
|
|
/// first be created in the parent's renderer process. That temporary sub-frame

/// navigation callbacks (2) for the transition from the temporary sub-frame to
|
|
/// the real sub-frame. The temporary sub-frame will not recieve or execute
|
|
/// commands during this transitional period (any sent commands will be
|
|
/// discarded).
