-// This class is a convenience class for handling editor key bindings defined |
-// in gtk keyboard theme. |
-// In gtk, only GtkEntry and GtkTextView support customizing editor key bindings |
-// through keyboard theme. And in gtk keyboard theme definition file, each key |
-// binding must be bound to a specific class or object. So existing keyboard |
-// themes only define editor key bindings exactly for GtkEntry and GtkTextView. |
-// Then, the only way for us to intercept editor key bindings defined in |
-// keyboard theme, is to create a GtkEntry or GtkTextView object and call |
-// gtk_bindings_activate_event() against it for the key events. If a key event |
-// matches a predefined key binding, corresponding signal will be emitted. |
-// GtkTextView is used here because it supports more key bindings than GtkEntry, |
-// but in order to minimize the side effect of using a GtkTextView object, a new |
-// class derived from GtkTextView is used, which overrides all signals related |
-// to key bindings, to make sure GtkTextView won't receive them. |
-// |
-// See third_party/WebKit/Source/WebCore/editing/EditorCommand.cpp for detailed |
-// definition of webkit edit commands. |
-// See webkit/glue/editor_client_impl.cc for key bindings predefined in our |
-// webkit glue. |
