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:].

I need to know when the contentRect of a WebView changes so I added
a WebUIDelegate listening to setContentRect:.
Problem: setContentRect: is never called.
I added more methods to the WebUIDelegate, listening to show/close,
focus/unfocus, set status text, set frame/content and mouse-move,
but none of them gets called except for mouse-move
(mouseDidMoveOverElement:).
Is there anything wrong with my code? I tested with both Safari 2
and Safari 3. For a minimal testcase, you can add the following
code to /Developer/Examples/WebKit/MiniBrowser/MyDocument.m, line
263. The only output to the console comes from the NSLog() in
mouseDidMoveOverElement:
- (void)webViewClose:(WebView *)sender
{
NSLog(@"WebView UI delegate:webViewClose");
}
- (void)webViewFocus:(WebView *)sender
{
NSLog(@"WebView UI delegate:webViewFocus");
}
- (void)webViewUnfocus:(WebView *)sender
{
NSLog(@"WebView UI delegate:webViewUnfocus");
}
- (void)webView:(WebView *)sender setStatusText:(NSString *)text
{
NSLog(@"WebView UI delegate:setStatusText %@", text);
}
- (void)webView:(WebView *)sender setFrame:(NSRect)frame
{
NSLog(@"WebView UI delegate:setFrame w=%f h=%f",
frame.size.width, frame.size.height);
}
- (void)webView:(WebView *)sender setContentRect:(NSRect)contentRect
{
NSLog(@"WebView UI delegate:setContentRect w=%f h=%f",
contentRect.size.width, contentRect.size.height);
}
- (void)webView:(WebView *)sender mouseDidMoveOverElement:
(NSDictionary *)elementInformation modifierFlags:(unsigned int)
modifierFlags
{
NSLog(@"WebView UI delegate:mouseDidMoveOverElement");
}
