|
// 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).
|
|
//
|
|
// (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.
|
|
// - 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.
|
|
// - 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
|
|
// will then be discarded after the real cross-origin sub-frame is created in
|
|
// the new/target renderer process. The client will receive cross-origin
|
|
// 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).
|
|
//
|
|
// When a new popup browser is created in a different origin from the parent
|
|
// browser, a temporary main frame object for the popup will first be created in
|
|
// the parent's renderer process. That temporary main frame will then be
|
|
// discarded after the real cross-origin main frame is created in the new/target
|
|
// renderer process. The client will recieve creation and initial navigation
|
|
// callbacks (1) for the temporary main frame, followed by cross-origin
|
|
// navigation callbacks (2) for the transition from the temporary main frame to
|
|
// the real main frame. The temporary main frame may receive and execute
|
|
// commands during this transitional period (any sent commands may be executed,
|
|
// but the behavior is potentially undesirable since they execute in the parent
|
|
// browser's renderer process and not the new/target renderer process).
|
|
//
|
|
// 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.
