[chromium] The chromium API needs a WebMouseEvent class

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Jay Civelli]

The WebKit::WebNode event listener API only has a WebMutationEvent.
For autofill related functionalities, we now need a WebMouseEvent class.

Initial patch

[Jay Civelli]

There is already a WebMouseEvent class defined in WebInputEvent.h used for different purposes.
Not sure what would be a good name for this one, used the really lame WebMouseEvent2 in the first patch :-(
Suggestions welcome.

Fixed style issues

Yeah, WebMouseEvent2 is obviously not going to cut it.  We probably should
rename the subclasses of WebInputEvent.  That way we don't have to change
our convention of using WebFoo for DOM thingies named Foo.  MouseEvent
should map to WebMouseEvent given that convention.

Maybe inner classes?  WebInputEvent::{Generic,Mouse,Wheel,Keyboard}?  The
downside to such a solution is that it forces the inclusion of WebInputEvent.h
in places that could previously just forward declare it.  We could also
try to do something using a union:

  struct WebInputEvent {
    enum {...} type;
    ... other common fields ...
    union {
      struct {
        ...
      } mouse;
      struct {
        ...
      } wheel;
      struct {
        ...
      } keyboard;
    } data;
  };

Then it would still be valid to forward declare 'struct WebInputEvent'.

I need to think about this more, but those are some ideas...

You can see this union approach in action here:

[Jay Civelli]

I don't think we can do the union, as the WebTouchEvent contains a WebTouchPoint which has a constructor and that I don't think it is OK for a union to have a member which has a non default constructor.
I guess we could make WebTouchPoint a struct with no constructor and make sure it is initialized properly were it is used.

May be going with the inner-class would be easier (although it prevents us from forward declaring the events)?

What do you think?

Adding missing files

WebKit/chromium/public/WebNode.h:102
 +      WEBKIT_API void addDOMEventListener(const WebString& eventType, WebDOMEventListener* listener, bool useCapture);
nit: these should just be named add/removeEventListener to match
how they are named in the DOM specification.

WebKit/chromium/src/EventListenerWrapper.h:50
 +  class EventListenerWrapperDOM : public EventListener {
EventListenerWrapperDOM is an awkward name.  can we rename the other
one DeprecatedEventListenerWrapper, and then use EventListenerWrapper?

otherwise, LGTM
