Bug 30175 – [Win] Windows DRT UIDelegate::doDragDrop does not return OLE drag-and-drop return value

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Daniel Bates]

We should have UIDelegate::doDragDrop return the OLE drag-and-drop return value just like the Windows API function it emulates, DoDragDrop <http://msdn.microsoft.com/en-us/library/ms678486%28VS.85%29.aspx>.

No test included because it is not possible to test this outside of unit testing.

I don't think this change is what we want. This will require that all WebKit clients that support the IWebUIDelegatePrivate interface implement doDragDrop. I think we want to leave this code as it was.

It would be nicer to just forward-declare HRESULT.

The rest of the DRT changes look fine.

As per Adam's comment, removed changes to WebDragClient::startDrag and in EventSender defined typedef for HRESULT, instead of including <window.h>.
