Thank you. If implementating the 'didFinishLoadForFrame' method is
to listen for browser finishing loading everything, then some please
in webkit code must call the didFinishLoadForFrame' to tell the
delegate that page load is done, right?
But when i search the code, i only find these places calling. None
of them is calling didFinishLoadForFrame on MacOS. Can you please
tell me what am i missing?
The easiest way to answer a question like this is to run Safari under
the debugger and set a breakpoint, then look at the backtrace.
