Summary scroll wheel events are ignored by all iframes

Reported 2006-12-18 15:54:23 PST
RenderPartObject::viewCleared() sets the m_ignoreWheelEvents flag on a view's EventHandler object for all iframes. This code looks pretty ancient, but the m_ignoreWheelEvents flag has been ignored up until recently; now iframe scrolling via the mouse wheel doesn't work. I think this is incorrect. I'll attach a patch to remove the offending line.

Is anyone using m_ignoreWheelEvents for any purpose?

(In reply to comment #2) > Is anyone using m_ignoreWheelEvents for any purpose? From what I can tell, it's only ever used by this code that sets it for all iframes.

Need more information. Who uses this flag? Is it used on Mac?

The only time setIgnoreWheelEvents() is called in the code is in RenderPartObject::viewCleared(). The only code that checks m_ignoreWheelEvents is in EventHandler::handleWheelEvent() (which early-outs if it is set).
