// Use of this source code is governed by a BSD-style license that can be

// WebCore provides hooks for several kinds of functionality, allowing separate
// classes termed "delegates" to receive notifications (in the form of direct
// function calls) when certain events are about to occur or have just occurred.
// In some cases, the delegate implements the needed functionality; in others,
// the delegate has some control over the behavior but doesn't actually
// implement it. For example, the UI delegate is responsible for showing a
// dialog box or otherwise handling a JavaScript window.alert() call, via the
// RunJavaScriptAlert() method. On the other hand, the editor delegate doesn't
// actually handle editing functionality, although it could (for example)
// override whether a content-editable node accepts editing focus by returning
// false from ShouldBeginEditing(). (It would also possible for a more
// special-purpose editing delegate to act on the edited node in some way, e.g.
// to highlight modified text in the DidChangeContents() method.)
// WebKit divides the delegated tasks into several different classes, but we
// combine them into a single WebViewDelegate. This single delegate encompasses
// the needed functionality of the WebKit UIDelegate, ContextMenuDelegate,
// PolicyDelegate, FrameLoadDelegate, and EditorDelegate; additional portions
// of ChromeClient and FrameLoaderClient not delegated in the WebKit
// implementation; and some WebView additions.
