Got it! Now moving on to this delegate method — in Cocoa Programming Quick Start, Daniel H. Steinberg gives: - (void)webView:(WebView *)sender didReceiveTitle:(NSString *)title forFrame:(WebFrame *)frame { [[sender window] setTitle:title]; } Which I translated as: def didReceiveTitle(title, forFrame:frame) sender.window(setTitle:title) end That should be correct. But what might be the cause for the delegate method never to be triggered? (That is, the window title never changes.) Thank y'all for your help, and for putting up with an old dog trying to learn new stuff.
I think you've translated that a little wrong. This is untested, but I'd suggest trying: def webView(sender, didReceiveTitle:title, forFrame:frame) sender.window.setTitle(title) end Does that sound right to anybody else? The method name should be the bit after the first ), and before the first :. Everything after that are args. Which means you can end up with ruby methods that look like they have the same name, but work because of the named args. Stuff like: def webView(sender, didFinishLoading:frame) end (and any other Webview notifications.) For what it's worth, I found Hillegass' Cocoa Programming for OSX book a big help for learning Cocoa andMacruby at the same time. Brad On 03/04/2009, at 7:11 PM, Frisco Del Rosario wrote:

Yep that's correct. Eloy
