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.

// CEF exposes views framework functionality via a hierarchy of CefView and
// related objects. While the goal is to accurately represent views framework
// capabilities there is not always a direct 1:1 mapping between the CEF
// implementation and the underlying views implementation. Certain liberties
// have been taken with the CEF API design to clarify the user experience.
//
// CEF implementation overview:
//
// CefView-derived classes (CefPanel, CefLabelButton, etc.) are implemented
// using a specialization of the CefViewImpl template. On Initialize() the
// CefViewImpl object creates an underlying views::View object via the
// CreateRootView() method. The views::View objects are implemented using a
// specialization of the CefViewView template. CefViewView extends the
// views::View-derived class and executes CefViewDelegate-derived callbacks by
// overriding views::View methods.
//
// Example 1: The CefBasicPanelImpl object created via CefPanel::CreatePanel()
// has the following object hierarchy:
//
// CefView => CefPanel =>
// CefViewImpl<views::View, CefPanel, CefPanelDelegate> =>
// CefPanelImpl<views::View, CefPanel, CefPanelDelegate> =>
// CefBasicPanelImpl.
//
// And the CefBasicPanelView object created via
// CefBasicPanelImpl::CreateRootView() has the following object hierarchy:
//
// views::View =>
// CefViewView<views::View, CefPanelDelegate> =>
// CefPanelView<views::View, CefPanelDelegate> =>
// CefBasicPanelView.
//
// Example 2: In some cases an intermediary type is required to meet CEF
// template requirements (e.g. CefViewView requires a no-argument constructor).

//
//
// General design considerations:
//
// CefView classes are ref-counted whereas views::View classes are not. There
// is generally a 1:1 relationship between CefView and views::View objects.
// However, there may be intermediary views::View objects that are not exposed
// by the CEF layer. For example:
// - views::Widget creates views::RootView and views::ContentView child objects;
// - views::ScrollView creates views::ScrollView::Viewport child objects.
//
// The views::View class exposes methods that are not applicable for a subset of
// views implementations. For example:
// - Calling AddChildView() on a views::LabelButton is unexpected;
// - Adding a child to a views::ScrollView requires calling the SetContents()
// method instead of AddChildView().
// To avoid user confusion CEF introduces a CefPanel type that extends CefView
// and exposes common child management functionality. Types that allow
// arbitrary children extend CefPanel instead of CefView.
//
//
// Object ownership considerations:
//
// On initial creation the CefViewImpl object owns an underlying views::View
// object (created by overriding the CreateRootView() method) and the
// views::View object holds a non-ref-counted reference to the CefViewImpl
// object. If a CefViewImpl is destroyed (all refs released) then the underlying
// views::View object is deleted.
//
// When a views::View object is parented to another views::View (via
// CefPanel::AddChildView or similar) the ownership semantics change. The
// CefViewImpl swaps its owned reference for an unowned reference and the
// views::View gains a ref-counted reference to the CefViewImpl
// (CefView::IsAttached() now returns true).
//
// When a parent views::View is deleted all child views::Views in the view
// hierarchy are also deleted (see [1] for exceptions). When this happens the
// ref-counted CefViewImpl reference held by the views::View is released. The
// CefViewImpl is deleted if the client kept no references, otherwise the
// CefViewImpl is marked as invalid (CefView::IsValid() now returns false).
//
// When a views::View is removed from the view hierarchy (via
// CefPanel::RemoveChildView or similar) the initial ownership state is
// restored. The CefViewImpl regains ownership of the views::View and the
// ref-counted CefViewImpl reference held by the views::View is released.
//
// The relationship between CefViewImpl and views::View objects is managed using
// the view_util:: functions. Type conversion is facilitated using the As*()
// methods exposed by CefView-derived classes and the CefViewAdapter interface
// implemented by CefViewImpl. See view_util.[cc|h] for implementation details.
//
// Some other object types are also tied to views::View lifetime. For example,
// CefLayout and the underling views::LayoutManager objects are owned by the
// views::View that they're assigned to. This relationship is managed using the
// layout_util:: functions in layout_util.[cc|h].
//
// [1] By default views::View objects are deleted when the parent views::View
// object is deleted. However, this behavior can be changed either
// explicitly by calling set_owned_by_client() or implicitly by using
// interfaces like WidgetDelegateView (where WidgetDelegate is-a View, and
// the View is deleted when the native Widget is destroyed). CEF
// implementations that utilize this behavior must take special care with
// object ownership management.
//
//
// To implement a new CefView-derived class:
//
// 1. Choose a views class to expose.
// * We'll create a new CefFooBar class which exposes a hypothetical
// views::FooBar class. The views::FooBar class might look like this:
//
// File ui/views/foo_bar.h:
//
// namespace views {
//
// // FooBar view does a task on child views.
// class FooBar : public View {
// public:
// FooBar();
//
// // Do a task.
// void DoTask();
// // Called when the task is done.
// virtual void OnTaskDone();
//
// // View methods:
// void Layout() override; // Implements custom layout of child views.
// };
//
// } // namespace views
//
// 2. Determine the existing CefView-derived class that the new view class
// should extend.
// * Since in this example CefFooBar can have arbitrary child views we'll
// have it extend CefPanel.
//
// 3. Determine whether the new view class can use an existing delegate class
// (like CefPanelDelegate) or whether it needs its own delegate class.
// * Since CefFooBar has an OnTaskDone() callback we'll add a new
// CefFooBarDelegate class to expose it.
//
// 4. Create new header files in the cef/include/views/ directory.
// * Using existing files as a model, the resulting header contents might
// look like this:
//
// File cef/include/views/cef_foo_bar.h:
//
// ///
// // A FooBar view does a task on child views.
// ///
// /*--cef(source=library)--*/
// class CefFooBar : public CefPanel {
// public:
// ///
// // Create a new FooBar.
// ///
// /*--cef(optional_param=delegate)--*/
// static CefRefPtr<CefFooBar> CreateFooBar(
// CefRefPtr<CefFooBarDelegate> delegate);
//

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.
