// Called when a browser has recieved a request to close. This may result

|
// directly from a call to cef_browser_host_t::*close_browser() or indirectly
|
|
// if the browser is parented to a top-level window created by CEF and the
|
|
// user attempts to close that window (by clicking the 'X', for example). The
|
|
// do_close() function will be called after the JavaScript 'onunload' event
|
|
// has been fired.
|
|
//
|
|
// An application should handle top-level owner window close notifications by
|
|
// calling cef_browser_host_t::try_close_browser() or
|
|
// cef_browser_host_t::CloseBrowser(false (0)) instead of allowing the window
|
|
// to close immediately (see the examples below). This gives CEF an
|
|
// opportunity to process the 'onbeforeunload' event and optionally cancel the
|
|
// close before do_close() is called.
|
|
//
|
|
// When windowed rendering is enabled CEF will internally create a window or
|
|
// view to host the browser. In that case returning false (0) from do_close()
|
|
// will send the standard close notification to the browser's top-level owner
|
|
// window (e.g. WM_CLOSE on Windows, performClose: on OS X, "delete_event" on
|
|
// Linux or cef_window_delegate_t::can_close() callback from Views). If the
|
|
// browser's host window/view has already been destroyed (via view hierarchy
|
|
// tear-down, for example) then do_close() will not be called for that browser
|
|
// since is no longer possible to cancel the close.
|
|
//
|
|
// When windowed rendering is disabled returning false (0) from do_close()
|
|
// will cause the browser object to be destroyed immediately.
|
|
//
|
|
// If the browser's top-level owner window requires a non-standard close
|
|
// notification then send that notification from do_close() and return true
|
|
// (1).
|
|
//
|
|
// The cef_life_span_handler_t::on_before_close() function will be called
|
|
// after do_close() (if do_close() is called) and immediately before the
|
|
// browser object is destroyed. The application should only exit after
|
|
// on_before_close() has been called for all existing browsers.
|
|
//
|
|
// The below examples describe what should happen during window close when the
|
|
// browser is parented to an application-provided top-level window.
|
|
//
|
|
// Example 1: Using cef_browser_host_t::try_close_browser(). This is
|
|
// recommended for clients using standard close handling and windows created
|
|
// on the browser process UI thread. 1. User clicks the window close button
|
|
// which sends a close notification to
|
|
// the application's top-level window.
|
|
// 2. Application's top-level window receives the close notification and
|
|
// calls TryCloseBrowser() (which internally calls CloseBrowser(false)).
|
|
// TryCloseBrowser() returns false so the client 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.
|
|
// CEF sends a close notification to the application's top-level window
|
|
// (because DoClose() returned false by default).
|
|
// 7. Application's top-level window receives the close notification and
|
|
// calls TryCloseBrowser(). TryCloseBrowser() returns true so the client
|
|
// allows the window close.
|
|
// 8. Application's top-level window is destroyed. 9. Application's
|
|
// on_before_close() handler is called and the browser object
|
|
// is destroyed.
|
|
// 10. Application exits by calling cef_quit_message_loop() if no other
|
|
// browsers
|
|
// exist.
|
|
//
|
|
// Example 2: Using cef_browser_host_t::CloseBrowser(false (0)) and
|
|
// implementing the do_close() callback. This is recommended for clients using
|
|
// non-standard close handling or windows that were not created on the browser
|
|
// process UI thread. 1. User clicks the window close button which sends a
|
|
// close notification to
|
|
// the application's top-level window.
|
|
// 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. Set a flag to indicate that the next close attempt will be allowed.
|
|
// B. Return false.
|
|
// 7. CEF sends an close notification to the application's top-level window.
|
|
// 8. Application's top-level window receives the close notification and
|
|
// allows the window to close based on the flag from #6B.
|
|
// 9. Application's top-level window is destroyed. 10. Application's
|
|
// on_before_close() handler is called and the browser object
|
|
// is destroyed.
|
|
// 11. Application exits by calling cef_quit_message_loop() if no other
|
|
// browsers
|
|
// exist.
