Ignore this. I tried to sneak it by but it is bad coding.

defaultEventHandler is a virtual function. Why not put this code in the HTMLPlugInImageElement class in the first place instead of down casting?

Yeah... that's what I ended up doing. I'll even admit I thought of doing it up front :(

I think this would be slightly clearer if you did the event->type() last.

Should be protected, not public. And as long as you are touching it, should add OVERRIDE.

Should add OVERRIDE. Could be private instead of protected.
