The OnFrameAttached callback relies on a round-trip to the
renderer process and may not be synchronized with OnLoadStart/
OnLoadEnd/OnMainFrameChanged callbacks.
Pass a new |popup_id| parameter to OnBeforePopup and call a new
OnBeforePopupAborted callback if the popup is aborted before
OnAfterCreated is called for the popup browser. Add new
CefBrowserHost::GetBrowserByIdentifier and GetOpenerIdentifier
methods to assist with retrieval of associated browsers.
In cefclient, clean up state when a popup is aborted and close
any associated popup browsers when the opener browser is closed.
This also works when running with `--use-default-popup`.
Fix implementation of CefBrowserView::RequestFocus for Chrome style
browsers. Match Alloy style behavior of requesting browser focus
(calling OnSetFocus) after initial navigation. Add CefView::HasFocus
and CefWindow::GetFocusedView that can be used in combination with
CefWindow::IsActive to determine global keyboard focus.
Update sample applications for the new behavior.
In cefclient:
- Browser receives initial focus via ViewsWindow::RequestBrowserFocus.
- When running with `--show-overlay-browser` (see #3790):
- Give initial focus to the overlay browser.
- Change the overlay popout shortcut to CTRL+SHIFT+O to avoid
assigning focus to the menu in the main window.
- Switching from overlay in the main window to popout browser
window will give focus to the popout browser.
- Switching from popout browser to overlay will leave current focus
unchanged (e.g. in the overlay browser, or somewhere else). User
gesture to activate the main window may be required on Mac/Linux.
- When running with `--no-active` don't give initial focus to either
browser.
In cefsimple:
- Browser receives initial focus via default handling.
Using cc_import + interface_library/shared_library to link libcef.lib causes
libcef.dll to be copied as a transitive dependency, leading to issues with
complex Bazel configs. Instead, we explicitly link libcef.lib in the binary
target (cc_binary + linkopts/additional_linker_inputs) and explicitly copy
libcef.dll to the target directory.
CefWindowImpl::CanHandleAccelerators was returning false for
accelerators triggered in the overlay BrowserView due to
IsWindowKey (called from NativeWidgetMac::IsActive) returning
false. View::CanHandleAccelerators, on the other hand, only
checks IsActive for Aura (non-MacOS) windows. We therefore
delegate to the View implementation for consistent handling.
These linker errors impact CEF builds but not Chromium builds due
to differences in application structure, and are becoming more
common with ongoing Chromium code refactoring.
When running via ASAN it may be necessary to set
`ASAN_OPTIONS=detect_odr_violation=0` to work around
https://github.com/google/sanitizers/issues/1017
When running with the overlay Browser enabled (`--show-overlay-browser`),
pressing Alt+O will move the overlay Browser to a new top-level Window.
Pressing Alt+O again or closing the new Window via the close button will
return the Browser to the overlay. Closing the Browser via `window.close()`
(in the new Window or overlay) will dismiss the overlay completely as
required to maintain consistent internal state. Detection of this state is
supported by the new CefBrowserHost::IsReadyToBeClosed method.
Draggable regions in the main Browser are updated to account for the
presence or absence of the overlay Browser. Support for draggable regions
in the overlay Browser in not implemented in cefclient.
Behavior with multiple overlays, `window.close()` and draggable regions
can be tested by adding `--hide-frame --hide-controls`.
TryCloseBrowser should potentially trigger JavaScript unload handlers
and return false. Add CefBrowserHost::IsReadyToBeClosed for detecting
mandatory close state. Enable, for Chrome style browsers, LifeSpanTest
that don't require DoClose(). Update related documentation.
Avoid a circular ownership dependency between CefBrowserViewImpl and
CefBrowserPlatformDelegate[Chrome]Views (owned by CefBrowserHostBase).
Trigger CefBrowserHostBase destruction when the last CefBrowserViewImpl
reference is released.
This fixes a number of shutdown crashes related to overlay CefBrowsers
still existing at CefShutdown.
Adds new `--show-overlay-browser` command-line flag that creates an
overlay containing an Alloy-style BrowserView. The main BrowserView
may be Chrome- (default) or Alloy-style (add `--use-alloy-style`).
This overlay will only be added to standalone (non-popup) windows.
Popups triggered via the overlay will receive standard Alloy-style
handling in cefclient (e.g. Views-hosted window). Add
`--use-default-popup` for default popup handling.
ChromeCommandDispatcherDelegate forwards accelerator events to
the FocusManager through NativeWidgetMacNSWindowHost::
HandleAccelerator. Always initialize it so that accelerators also
work in a CefWindow without a BrowserView.
Some downloaded file types [1] default to opening in a Browser. Open
requests for these file types originating from the Download bubble UI
should route to the source Browser (call OnOpenURLFromTab). If
OnOpenURLFromTab is unhandled proceed with the default Chrome behavior
of opening the URL in a new default Browser.
[1] PDF, html, etc. For the complete list of file types see
ChromeDownloadManagerDelegate::IsOpenInBrowserPreferredForFile.
