// the browser is parented to another window and that other window needs to
|
|
// receive close notification via some non-standard technique.
|
|
//
|
|
// If an application provides its own top-level window it should handle OS
|
|
// close notifications by calling cef_browser_host_t::CloseBrowser(false (0))
|
|
// instead of immediately closing (see the example below). This gives CEF an
|
|
// opportunity to process the 'onbeforeunload' event and optionally cancel the
|
|
// close before do_close() is called.
|
|
//
|
|
// The cef_life_span_handler_t::OnBeforeclose() function will be called
|
|
// immediately before the browser object is destroyed. The application should
|
|
// only exit after OnBeforeclose() has been called for all existing browsers.
|
|
//
|
|
// If the browser represents a modal window and a custom modal loop
|
|
// implementation was provided in cef_life_span_handler_t::run_modal() this
|
|
// callback should be used to restore the opener window to a usable state.
|
|
//
|
|
// By way of example consider what should happen during window close when the
|
|
// browser is parented to an application-provided top-level OS window. 1.
|
|
// User clicks the window close button which sends an OS close
|
|
// notification (e.g. WM_CLOSE on Windows, performClose: on OS-X and
|
|
// "delete_event" on Linux).
|
|
// 2. Application's top-level window receives the close notification and:
|
|
// A. Calls CefBrowserHost::CloseBrowser(false).
|
|
// B. Cancels the window close.
|
|
// 3. JavaScript 'onbeforeunload' handler executes and shows the close
|
|
// confirmation dialog (which can be overridden via
|
|
// CefJSDialogHandler::OnBeforeUnloadDialog()).
|
|
// 4. User approves the close. 5. JavaScript 'onunload' handler executes. 6.
|
|
// Application's do_close() handler is called. Application will:
|
|
// A. Call CefBrowserHost::ParentWindowWillClose() to notify CEF that the
|
|
// parent window will be closing.
|
|
// B. Set a flag to indicate that the next close attempt will be allowed.
|
|
// C. Return false.
|
|
// 7. CEF sends an OS close notification. 8. Application's top-level window
|
|
// receives the OS close notification and
|
|
// allows the window to close based on the flag from #6B.
|
|
// 9. Browser OS window is destroyed. 10. Application's
|
|
// cef_life_span_handler_t::OnBeforeclose() handler is called and
|
|
// the browser object is destroyed.
|
|
// 11. Application exits by calling cef_quit_message_loop() if no other

// browsers
|
|
// exist.
