[webkit-help] Need help in understanding Webkit handling of AJAX dynamic content

[n179911]

Hi,

I am trying to learn how Webkit handling of AJAX dynamic content,
meaning when user clicks an image, new content shows up on the page.
Where in the Webkit code I should look at to learn
1. how it handles mouse click
2. how it add new content to the page
3. how it repaints that part of the page

Thank you.
