Disable rubber-band scrolling for webview in lion

I have a Cocoa webview, with a web application in it. The web application has a fixed toolbar itself, and with the elastic scrolling, and the toolbar coming below the top, it looks bad. Is there a way to disable the elastic/rubber-band scrolling, or at least keep the toolbar from moving with the rest of the content? I can modify the web app 开发者_StackOverflow社区as much as neede.

If you're interested in doing it from the WebView and Cocoa perspective, you can also implement the finish load delegate, grab the scroll view, and disable elasticity:

- (void)webView:(WebView *)sender didFinishLoadForFrame:(WebFrame *)frame {
    NSScrollView *mainScrollView = sender.mainFrame.frameView.documentView.enclosingScrollView;
    [mainScrollView setVerticalScrollElasticity:NSScrollElasticityNone]; 
    [mainScrollView setHorizontalScrollElasticity:NSScrollElasticityNone];
}

Maybe this article would help you.

In short: disable overflow on HTML and BODY, add a wrapper with overflow:auto around all the page contents

I know this comment likely won't be accepted, since there's already an answer.

However, there's an actual method you can call on your NSView (docs here):

[[[webView mainFrame] frameView] setAllowsScrolling:NO];
