[webkit-qt] Accessing private object/class in Qt from DRT

[Robert Hogan]

Hi there,

So I've concluded (without confirming it in practice yet) that in order to 
support Drag and Drop in layout tests the DRT needs to be able to send the 
mouseUp() event to the event loop in QDragManager. I believe sending it to 
QWebView doesn't work for the simple reason that QDragManager has the event 
loop when a drag is in progress and unless it receives the 
QEvent::MouseButtonRelease it's just going to block the main event loop.

This matches the way the tests currently fail and my experimentation when 
trying to get them to work.

So in order to send a MouseButtonRelease event to QDragManager's event loop 
it needs to be accessible from the DRT and it is not public API in Qt.

So what to do? I can try sending a QDropAction to QWebPage but I suspect 
that will get me nowhere as long as the eventloop in QDragManager is still 
running. A quick grep of qt sources doesn't reveal any precedent for 
creating accessors to private Qt classes from QtWebKit.

Does the above sound sensible? If so, what's the best way to solve this?

Thanks,
Robert
