35// CreateShortcutViewCommon implements a dialog that asks user where to create
36// the shortcut for given web app.  There are two variants of this dialog:
37// Shortcuts that load a URL in an app-like window, and shortcuts that load
38// a chrome app (the kind you see under "apps" on the new tabs page) in an app
39// window.  These are implemented as subclasses of CreateShortcutViewCommon.
