In WebKit1, WebKitWebView implements GtkScrollable and you are supposed
to use it inside a GtkScrolledWindow.

Why are you using a GtkEventBox?

When using the C API, WKView doesn't implement GtkScrollable, so it
shouldn't be used with a GtkScrolledWindow. In this case the view will
use WebKit internal scrollbars instead of the GTK ones like with any
other frame. 
When using the GTK+ API (not available yet) WebKitWebView will
implement GtkScrollable so that you will be able to use the view inside
a GtkScrolledWindow and use gtk_scrolled_window_set_policy().
