Create a ChromeBrowserHostImpl for every Chrome tab (see issue #2969) The Browser object represents the top-level Chrome browser window. One or more tabs (WebContents) are then owned by the Browser object via TabStripModel. A new Browser object can be created programmatically using "new Browser" or Browser::Create, or as a result of user action such as dragging a tab out of an existing window. New or existing tabs can also be added to an already existing Browser object. The Browser object acts as the WebContentsDelegate for all attached tabs. CEF integration requires WebContentsDelegate callbacks and notification of tab attach/detach. To support this integration we add a cef::BrowserDelegate (ChromeBrowserDelegate) member that is created in the Browser constructor and receives delegation for the Browser callbacks. ChromeBrowserDelegate creates a new ChromeBrowserHostImpl when a tab is added to a Browser for the first time, and that ChromeBrowserHostImpl continues to exist until the tab's WebContents is destroyed. The associated WebContents object does not change, but the Browser object will change when the tab is dragged between windows. CEF callback logic is shared between the chrome and alloy runtimes where possible. This shared logic has been extracted from CefBrowserHostImpl to create new CefBrowserHostBase and CefBrowserContentsDelegate classes. The CefBrowserHostImpl class is now only used with the alloy runtime and will be renamed to AlloyBrowserHostImpl in a future commit.

Add chrome runtime support for more callbacks and ceftests (see issue #2969) This change adds support for: - Protocol and request handling. - Loading and navigation events. - Display and focus events. - Mouse/keyboard events. - Popup browsers. - Callbacks in the renderer process. - Misc. functionality required for ceftests. This change also adds a new CefBrowserProcessHandler::GetCookieableSchemes callback for configuring global state that will be applied to all CefCookieManagers by default. This global callback is currently required by the chrome runtime because the primary ProfileImpl is created via ChromeBrowserMainParts::PreMainMessageLoopRun (CreatePrimaryProfile) before OnContextCreated can be called. ProfileImpl will use the "C:\Users\[user]\AppData\Local\CEF\User Data\Default" directory by default (on Windows). Cookies may persist in this directory when running ceftests and may need to be manually deleted if those tests fail. Remaining work includes: - Support for client-created request contexts. - Embedding the browser in a Views hierarchy (cefclient support). - TryCloseBrowser and DoClose support. - Most of the CefSettings configuration. - DevTools protocol and window control (ShowDevTools, ExecuteDevToolsMethod). - CEF-specific WebUI pages (about, license, webui-hosts). - Context menu customization (CefContextMenuHandler). - Auto resize (SetAutoResizeEnabled). - Zoom settings (SetZoomLevel). - File dialog runner (RunFileDialog). - File and JS dialog handlers (CefDialogHandler, CefJSDialogHandler). - Extension loading (LoadExtension, etc). - Plugin loading (OnBeforePluginLoad). - Widevine loading (CefRegisterWidevineCdm). - PDF and print preview does not display. - Crash reporting is untested. - Mac: Web content loads but does not display.

Implement Views framework on Windows and Linux (issue #1749). - 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.

Implement off-screen rendering support using delegated rendering (issue #1257). This implementation supports both GPU compositing and software compositing (used when GPU is not supported or when passing `--disable-gpu --disable-gpu-compositing` command-line flags). GPU-accelerated features (WebGL and 3D CSS) that did not work with the previous off-screen rendering implementation do work with this implementation when GPU support is available. Rendering now operates on a per-frame basis. The frame rate is configurable via CefBrowserSettings.windowless_frame_rate up to a maximum of 60fps (potentially limited by how fast the system can generate new frames). CEF generates a bitmap from the compositor backing and passes it to CefRenderHandler::OnPaint. The previous CefRenderHandler/CefBrowserHost API for off-screen rendering has been restored mostly as-is with some minor changes: - CefBrowserHost::Invalidate no longer accepts a CefRect region argument. Instead of invalidating a specific region it now triggers generation of a new frame. - The |dirtyRects| argument to CefRenderHandler::OnPaint will now always be a single CefRect representing the whole view (frame) size. Previously, invalidated regions were listed separately. - Linux: CefBrowserHost::SendKeyEvent now expects X11 event information instead of GTK event information. See cefclient for an example of converting GTK events to the necessary format. - Sizes passed to the CefRenderHandler OnPaint and OnPopupSize methods are now already DPI scaled. Previously, the client had to perform DPI scaling. - Includes drag&drop implementation from issue #1032. - Includes unit test fixes from issue #1245. git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@1751 5089003a-bbd8-11dd-ad1f-f1f9622dbc98

GPU-accelerated features (WebGL and 3D CSS) that did not work with the previous off-screen rendering implementation do work with this implementation when GPU support is available. Rendering now operates on a per-frame basis. The frame rate is configurable via CefBrowserSettings.windowless_frame_rate up to a maximum of 60fps (potentially limited by how fast the system can generate new frames). CEF generates a bitmap from the compositor backing and passes it to CefRenderHandler::OnPaint. The previous CefRenderHandler/CefBrowserHost API for off-screen rendering has been restored mostly as-is with some minor changes: - CefBrowserHost::Invalidate no longer accepts a CefRect region argument. Instead of invalidating a specific region it now triggers generation of a new frame. - The |dirtyRects| argument to CefRenderHandler::OnPaint will now always be a single CefRect representing the whole view (frame) size. Previously, invalidated regions were listed separately. - Linux: CefBrowserHost::SendKeyEvent now expects X11 event information instead of GTK event information. See cefclient for an example of converting GTK events to the necessary format. - Sizes passed to the CefRenderHandler OnPaint and OnPopupSize methods are now already DPI scaled. Previously, the client had to perform DPI scaling. - Includes drag&drop implementation from issue #1032. - Includes unit test fixes from issue #1245. git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@1751 5089003a-bbd8-11dd-ad1f-f1f9622dbc98

Implement Views framework on Windows and Linux (issue #1749). - 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.

Add support for direct DevTools protocol messaging (fixes issue #2961). This change allows the client to directly send and receive DevTools protocol messages (send method calls, and receive method results and events) without requiring a DevTools front-end or remote-debugging session. This change includes additional supporting changes: - Add a new CefRequestHandler::OnDocumentAvailableInMainFrame callback (see issue #1454). - Add a CefParseJSON variant that accepts a UTF8-encoded buffer. - Add a `--devtools-protocol-log-file=<path>` command-line flag for logging protocol messages sent to/from the DevTools front-end while it is displayed. This is useful for understanding existing DevTools protocol usage. - Add a new "libcef_static_unittests" executable target to support light-weight unit tests of libcef_static internals (e.g. without requiring exposure via the CEF API). Files to be unittested are placed in the new "libcef_static_unittested" source_set which is then included by both the existing libcef_static library and the new unittests executable target. - Linux: Remove use_bundled_fontconfig=false, which is no longer required and causes unittest build errors (see issue #2424). This change also adds a cefclient demo for configuring offline mode using the DevTools protocol (fixes issue #245). This is controlled by the "Offline mode" context menu option and the `--offline` command-line switch which will launch cefclient in offline mode. When cefclient is offline all network requests will fail with ERR_INTERNET_DISCONNECTED and navigator.onLine will return false when called from JavaScript in any frame. This mode is per-browser so newly created browser windows will have the default mode. Note that configuring offline mode in this way will not update the Network tab UI ("Throtting" option) in a displayed DevTools front-end instance.
