Chrome design changed to rounded top corners by default with
Chrome Refresh 2023. Square corners look better when the toolbar
is part of a custom Views-hosted layout, like in cefclient.
Chromium considers initially-minimized windows to be visible at
creation time in the Aura layer. This confuses the native occlusion
detector which knows that the OS window is initially hidden due to
IsIconic returning true. Start occlusion tracking with consistent
state by delaying enablement until the initially-minimized window is
restored for the first time.
- Adds `--initial-show-state=hidden` support for cefclient and cefsimple
where the window launches as initially hidden (no dock thumbnail).
- Adds `--hide-window-on-close` support for cefclient where clicking the
red traffic light button hides the window instead of closing it.
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.
Adds a new CefBrowserProcessHandler::OnAlreadyRunningAppRelaunch
callback for when an already running app is relaunched with the
same CefSettings.root_cache_path.
Client apps should check the CefInitialize() return value for early
exit of the relaunch source process.
- chrome: Disable upgrade/downgrade behavior (see #3608)
- chrome: Disable process singleton behavior (see #3609)
- chrome: Disable config as default system browser (see #3613)
This fixes the app icon for default Chrome windows such as DevTools
and Task Manager.
An ICON with value IDR_MAINFRAME (101) will be loaded from the main
executable is available. Otherwise, the default Chromium ICON will be
loaded from libcef.dll.
Cookies (and other credentials) will be excluded when appropriate by
downgrading |credentials_mode| from kSameOrigin to kOmit.
Improve logic for Origin header inclusion, including a fix for
Referrer/Origin calculation in URLRequestJob::ComputeReferrerForPolicy
when used with custom standard schemes.
Specify correct CookiePartitionKeyCollection when loading cookies.
To test:
- Run tests from https://browseraudit.com/ with and without
`--disable-request-handling-for-testing`. Results are the same.
- Run `ceftests --gtest_filter=CorsTest.*`.
Add new CefBrowserHost::[Can]ExecuteChromeCommand methods for executing
arbitrary Chrome commands.
Add support for existing CefBrowserHost::ShowDevTools, CloseDevTools and
HasDevTools methods.
DevTools windows now support the same Views callbacks as normal popup
windows with the new CefLifeSpanHandler::OnBeforeDevToolsPopup callback
as the DevTools-specific equivalent of OnBeforePopup.
Always create DevTools as an undocked window to support use of
ShowDevTools with default Chrome browser windows.
To test:
Run `ceftests --enable-chrome-runtime [--use-views]
--gtest_filter=V8Test.OnUncaughtExceptionDevTools`
OR:
1. Run `cefclient --enable-chrome-runtime [--use-native]`
2. Select "Show DevTools", "Close DevTools" or "Inspect" from the
right-click menu.
3. Notice that the DevTools window is Views-hosted (or native-hosted)
and works as expected.
Add --use-default-popup to get a default styled popup in step 3.
When running ceftests with Views enabled always close the CefWindow
when the browser is destroyed and wait for both CefBrowser and
CefWindow destruction before signaling test completion.
To test:
Run `ceftests --enable-chrome-runtime --use-views
--gtest_filter=FrameHandlerTest.OrderMainPopup*:RequestContextTest.PopupNavDestroyParent*`
Disable Chrome policy management by default. Add CefSettings.chrome_policy_id
which, when configured, enables Chrome policy management. See
https://support.google.com/chrome/a/answer/9037717 for background.
To test:
- Start with a machine where Google Chrome is managed.
- Run `cefclient --enable-chrome-runtime --url=chrome://policy/`
There should be no configured policies.
- Run `cefclient --enable-chrome-runtime --url=chrome://policy/
--enable-chrome-policy`
Configured Platform properties should match Google Chrome.
- Run `cefclient --enable-chrome-runtime --url=chrome://policy/
--enable-chrome-policy --enable-chrome-browser-cloud-management`
Configured Platform and Cloud properties should match Google Chrome.
Use the same code path for all fullscreen transitions so that Chrome UI updates
correctly. All user-initiated fullscreen transitions now result in
CefWindowDelegate::OnWindowFullscreenTransition callbacks.
A modal dialog is a child CefWindow that implements some special behaviors
relative to a parent CefWindow. Like any CefWindow it can be framed with
titlebar or frameless, and optionally contain draggable regions (subject to
platform limitations described below). Modal dialogs are shown centered on
the parent window (inside a single display) and always stay on top of the
parent window in z-order. Sizing behavior and available window buttons are
controlled via the usual CefWindowDelegate callbacks. For example, the dialog
can have a preferred size with resize, minimize and maximize disabled (via
GetPreferredSize, CanResize, CanMinimize and CanMaximize respectively).
This change adds support for two modality modes. With window modality all
controls in the parent window are disabled. With browser modality only the
browser view in the parent window is disabled.
Both modality modes require that a valid parent window be returned via
GetParentWindow. For window modality return true from IsWindowModalDialog
and call CefWindow::Show. For browser modality return false from
IsWindowModalDialog (the default value) and call
CefWindow::ShowAsBrowserModalDialog with a reference to the parent window's
browser view.
Window modal dialog behavior depends on the platform. On Windows and
Linux these dialogs have a titlebar and can be moved independent of the
parent window. On macOS these dialogs do not have a titlebar, move with
the parent window, and do not support draggable regions (because they are
implemented using sheets). On Linux disabling the parent window controls
requires a window manager the supports _NET_WM_STATE_MODAL.
Browser modal dialog behavior is similar on all platforms. The dialog will
be automatically sized and positioned relative to the parent window's
browser view. Closing the parent window or navigating the parent browser
view will dismiss the dialog. The dialog can also be moved independent of
the parent window though it will be recentered when the parent window
itself is resized or redisplayed. On MacOS the dialog will move along with
the parent window while on Windows and Linux the parent window can be moved
independently.
To test: Use the Tests > Dialog Window menu option in cefclient with Views
enabled (`--use-views` or `--enable-chrome-runtime` command-line flag).
Browser modal dialog is the default behavior. For window modal dialog add
the `--use-window-modal-dialog` command-line flag.
