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.
The cefclient sample app will persist window state across application restart
if run with views, cache_path and persist_user_references enabled.
To test:
1. Run `cefclient --use-views --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.
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.
To test:
Run `cefclient.exe --use-views --hide-frame --hide-controls`
Add `--enable-chrome-runtime` for the same behavior using the Chrome location
bar instead of a text field.
- Convert scoped_ptr to std::unique_ptr from <memory>
- Convert arraysize to base::size from include/base/cef_cxx17_backports.h
- Convert NULL to nullptr
- Include include/base/cef_callback.h instead of include/base/cef_bind.h
- Implicit conversion of CefRefPtr<T> or scoped_refptr<T> to T* is gone;
use .get() instead
See the issue for additional details.
- Add CefRequestContext::LoadExtension, CefExtension, CefExtensionHandler and
related methods/interfaces.
- Add chrome://extensions-support that lists supported Chrome APIs.
- Add CefBrowserHost::SetAutoResizeEnabled and CefDisplayHandler::OnAutoResize
to support browser resize based on preferred web contents size.
- views: Add support for custom CefMenuButton popups.
- cefclient: Run with `--load-extension=set_page_color` command-line flag for
an extension loading example. Add `--use-views` on Windows and Linux for an
even better example.
- Add Views header files in a new include/views directory.
- Add initial top-level window (CefWindow), control (CefBrowserView,
CefLabelButton, CefMenuButton, CefPanel, CefScrollView,
CefTextfield) and layout (CefBoxLayout, CefFlowLayout) support.
See libcef/browser/views/view_impl.h comments for implementation
details.
- Add Views example usage in cefclient and cefsimple and Views unit
tests in cef_unittests. Pass the `--use-views` command-line flag to
cefclient, cefsimple and cef_unittests to run using the Views
framework instead of platform APIs. For cefclient and cefsimple
this will create the browser window and all related functionality
using the Views framework. For cef_unittests this will run all
tests (except OSR tests) in a Views-based browser window. Views-
specific unit tests (`--gtest_filter=Views*`) will be run even if
the the `--use-views` flag is not specified.
- Pass the `--hide-frame` command-line flag to cefclient to demo a
frameless Views-based browser window.
- Pass the `--hide-controls` command-line flag to cefclient to demo a
browser window without top controls. This also works in non-Views
mode.
- Pass the `--enable-high-dpi-support` command-line flag to
cef_unittests on Windows to test high-DPI support on a display
that supports it.
- Add CefImage for reading/writing image file formats.
- Add CefBrowser::DownloadImage() for downloading image URLs as a
CefImage representation. This is primarily for loading favicons.
- Add CefMenuModel::CreateMenuModel() and CefMenuModelDelegate for
creating custom menus. This is primarily for use with
CefMenuButton.
- Add CefBrowser::TryCloseBrowser() helper for closing a browser.
Also improve related documentation in cef_life_span_handler.h.
- Rename cef_page_range_t to cef_range_t. It is now also used by
CefTextfield.
- Remove CefLifeSpanHandler::RunModal() which is never called.
- Add draggable regions example to cefclient.
