Hello everyone, I've just started diving into webkit development, so please excuse the inevitable ignorance.
My goal is to modify the scrolling behavior. Specifically, I want to force mouse wheel scrolling, to scroll one page -- instead of a certain increment. I've looked through the source code and attempted to trace execution with gdb, but I still can't find the appropriate place for modification. I can't understand how events are processed and dispatched right now. I've started at the top. Events seem to come into EventHandler.cpp (and on my Mac, EventHandlerMac.cpp) and then are passed on to WebCore::FrameView (which is in fact a WebCore::ScrollView). Then it looks like these messages are passed onto the individual widgets on the page. Backtrace in one of the function is EventHandler.cpp or ScrollView.cpp reveal that the originator of these messages is a native NSScrollView class. So, FrameView is way down below in the chain of events. Additionally, if I disable EventHandler::handleWheelEvent (by inserting a return statement at the top) the scrolling behavior still functions correctly. So the scrolling behavior is defined elsewhere, and I'm having a tough time pinpointing where that is. So: #1 If you've read this far, does my summary above look correct? #2 Does Safari bind to webkit in a different way than say a Qt browser? I'm running my session with WebKitTools/Scripts/debug-safari. #3 Where is the scrolling behavior controlled? If this post is more appropriate in webkit-dev please let me know. I'd appreciate any tips anyone might have!
