[webkit-dev] Most methods in WebUIDelegate are not getting called

[Geoffrey Garen]

setContentRect: is only called when opening a new window through  
JavaScript, and only with Safari 2.

In general, these methods are not notifications -- they are requests.  
So, for example, a user resize of the window may change the WebView's  
contentRect but, because the user  -- not WebKit -- requested the  
change, you will not receive a setContentRect: call.

NSView has notifications about frame and bounds changes. Perhaps  
those will solve your problem. See, for example, +[NSView  
setPostsFrameChangedNotifications:].
