- chrome: Disable upgrade/downgrade behavior (see #3608)
- chrome: Disable process singleton behavior (see #3609)
- chrome: Disable config as default system browser (see #3613)
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.
This adds support for the three-finger-swipe navigation gesture with
Alloy/Views. The default implementation matches the Chrome runtime
and navigates the browser back/forward. We also add an Alloy/Views-
specific client callback in CefBrowserViewDelegate for optional
custom handling of the gesture event.
This is intended for usage with frameless windows that show the standard window
buttons, where resizing the title bar height changes the button offset. Returning a
different value from CefWindowDelegate::GetTitlebarHeight and forcing a resize of
the NSWindow's theme frame (see ViewsWindow::NudgeWindow) will update the
title bar height.
To test:
1. Run `cefclient --use-views --hide-frame --show-window-buttons --url=http://tests/window`
2. Enter a new value for title bar height and click the "Set Titlebar Height" button
Frameless windows now display as expected. Default traffic light buttons can
optionally be shown at configurable vertical position. Layout respects text
direction.
- 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 Windows 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.

On Windows these new CefDisplay methods convert between screen pixel coordinates
and screen DIP coordinates. On macOS and Linux these methods just return a copy
of the input coordinates.
- 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).
This change provides a generic solution for active (key) window tracking that
works with both Views-hosted and native windows on MacOS. With this new approach
we can now successfully route top menu actions to the currently active window.
Prior to this change CEF's Views API was using focus notifications as a proxy
for window activation notifications. That doesn't work on MacOS where NSWindow
activation (key status) is independent of NSView focus (first responder) status,
and changes in activation don't necessarily generate focus notifications (see
NativeWidgetMac::OnWindowKeyStatusChanged). To make this work reliably on all
platforms we now expose a CefWindowDelegate::OnWindowActivationChanged callback.
This change also fixes an uninitialized variable
(RootWindowMacImpl::with_extension_) that was causing flaky behavior in
RootWindowManager::OnRootWindowActivated.
To test:
1. Run `cefclient [--use-views]`
2. Select Popup Window from the Tests menu. Do not explicitly activate the popup
window (e.g. don't click on it).
3. Verify that further Tests menu actions go to the popup window.
4. Change activation to a first window by clicking on it. Verify that Test
menu actions go to that window.
5. Close the currently active window. Do not explicitly activate the remaining
window (e.g. don't click on it).
6. Verify that Test menu actions go to the only remaining window.
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.
- Remove CefRequestContextHandler::OnBeforePluginLoad and
CefRequestContext::PurgePluginListCache (fixes issue #3047). These methods
stopped being relevant after the removal of Flash support in January 2021.
The last remaining PPAPI plugin (PDF viewer) will switch to a non-plugin
implementation in the near future (see https://crbug.com/702993#c58) and
functionality related to plugin filtering has already been removed in
https://crrev.com/343ae351c9.
