Frame identifiers have changed from int64_t to string type. This is due
to https://crbug.com/1502660 which removes access to frame routing IDs
in the renderer process. New cross-process frame identifiers are 160-bit
values (32-bit child process ID + 128-bit local frame token) and most
easily represented as strings. All other frame-related expectations and
behaviors remain the same.
- chrome: Disable upgrade/downgrade behavior (see #3608)
- chrome: Disable process singleton behavior (see #3609)
- chrome: Disable config as default system browser (see #3613)
- mac: Xcode 14.0 with macOS SDK 13.0 is now required.
- Remove CefRequestHandler::OnQuotaRequest because persistent quota is no
longer supported (see https://crbug.com/1208141)
The cefclient sample app on macOS will persist window state across application
restart if run with cache_path and persist_user_references enabled.
To test:
1. Run `cefclient --cache-path=/path/to/cache --persist-user-preferences`
2. Move or resize the window, maximize, minimize, etc.
3. Exit cefclient.
4. Run cefclient again with the same arguments. The previous window state will
be restored.
Use ScreenWin functions to correctly compute DIP/pixel conversions for
CEF-created top-level windows.
Fix incorrect DIPToScreenRect usage in DesktopWindowTreeHostWin when
|has_external_parent_| is true.
DesktopWindowTreeHostWin ("Chrome_WidgetWin_0") focus needs to be set before
the associated call to WebContents::Focus. In the case of mouse click events,
this means ::SetFocus needs to be called explicitly. See updated comments in
CefBrowserPlatformDelegateNativeWin::SetFocus.
DesktopWindowTreeHostWin ("Chrome_WidgetWin_0") focus needs to be set
synchronously in response to the parent window WM_SETFOCUS message and
before the associated call to WebContents::Focus. See updated comments in
CefBrowserPlatformDelegateNativeWin::SetFocus.
Popup windows will be created on the display that best matches the requested
coordinates. The requested size will apply to the content area (as required by
JS documentation) and window size will be reduced if necessary to fit within the
target display. The requested origin will apply to the window (including frame)
and will be modified if necessary so that the window is fully visible on the
target display.
This change does not implement popup positioning for cefclient which uses an
application-created parent window.
This change grants access to the getScreenDetails JS API without user prompt.
- Windows: SDK version 10.0.20348.0 is now required.
- MacOS: SDK version 12.3 (Xcode 13.3) is now required.
- Legacy swiftshader binaries (`swiftshader/*` on Win/Linux and
`libswiftshader_*.dylib` on MacOS) have been removed (see issue #3176).
All file dialogs irrespective of source, platform and runtime will now be
routed through CefFileDialogManager and trigger CefDialogHandler callbacks
(see issue #3293).
Adds Chrome runtime support for CefBrowserHost::RunFileDialog and
CefDialogHandler callbacks.
Adds Alloy runtime support for internal GTK file and print dialogs on Linux
subject to the following limitations:
1. Internal GTK implementation:
- Cannot be used with multi-threaded-message-loop because Chromium's
internal GTK implementation is not thread-safe (does not use GDK threads).
- Dialogs will not be modal to application windows when used with off-screen
rendering due to lack of access to the client's top-level GtkWindow.
2. Cefclient CefDialogHandler implementation:
- Cannot be used with Views because it requires a top-level GtkWindow.
Due to the above limitations no dialog implementation is currently provided for
Views + multi-threaded-message-loop on Linux. In cases where both
implementations are supported the cefclient version is now behind an optional
`--use-client-dialogs` command-line flag.
Expressly forbids multiple simultaneous file dialogs with the internal platform
implementation which uses modal dialogs. CefDialogHandler will still be notified
and can optionally handle each request without a modal dialog (see issue #3154).
Removes some RunFileDialog parameters that are not supported by the Chrome file
dialog implementation (selected_accept_filter parameter, cef_file_dialog_mode_t
overwrite/read-only flags).
Switch to using aura::CursorLoader which knows how to load system, non-system
and pak cursor resources.
On Windows, cursors will be loaded via LoadCursor first if available with a
fallback to pak file if necessary (like with component builds).
On Linux, all non-system cursor resources will be loaded from pak file. Cursors
may be loaded asynchronously resulting in the default (pointer) cursor being
returned on the first request.
Popup windows will be created on the display that best matches the requested
coordinates. The requested size will apply to the content area (as required by
JS documentation) and window size will be reduced if necessary to fit within the
target display. The requested origin will apply to the window (including frame)
and will be modified if necessary so that the window is fully visible on the
target display.
This change adds a `--use-default-popup` command-line option to cefclient. When
specified, popup windows will be created with default styling (e.g. without an
application-provided native parent window).
This change also adds some reasonable default window bounds in cases where they
are not specified by the client.
This change adds Chrome runtime support on Windows and Linux for creating a
browser parented to a native window supplied by the client application.
Expected API usage and window behavior is similar to what already exists with
the Alloy runtime. The parent window handle should be specified by using
CefWindowInfo::SetAsChild in combination with the CefBrowserHost::CreateBrowser
and CefLifeSpanHandler::OnBeforePopup callbacks.
The previously existing behavior of creating a fully-featured Chrome browser
window when empty CefWindowInfo is used with CreateBrowser remains unchanged
and Views is still the preferred API for creating top-level Chrome windows
with custom styling (e.g. title bar only, frameless, etc).
The cefclient Popup Window test with a native parent window continues to crash
on Linux with both the Alloy and Chrome runtimes (see issue #3165).
Also adds Chrome runtime support for CefDisplayHandler::OnCursorChange.
To test:
- Run `cefclient --enable-chrome-runtime [--use-views]` for the default (and
previously existing) Views-based behavior.
- Run `cefclient --enable-chrome-runtime --use-native` for the new native
parent window behavior.
- Run `cefclient --enable-chrome-runtime --use-native --no-activate` and the
window will not be activated (take input focus) on launch (Windows only).
- Run `cefclient --enable-chrome-runtime [--use-views|--use-native]
--mouse-cursor-change-disabled` and the mouse cursor will not change on
mouseover of DOM elements.
