Re: Not receiving mouseDown/Up events in borderless window . . .

Since the window is transparent and the view is not, maybe the view is actually getting the mouse event? Maybe. But why does it work on Snow Leopard? I will test your theory out and get back to you. I'm not even sure the content-view is a responder but I'll check that out too. -Michae

Retaining a NSURL and retaining its -path

In my controller, one of my instance variables is a NSURL and I retain it because I pass it to a 2nd controller. In my second controller, I extract [myURL path] and look at it in a secondary thread loop and everything works fine. I began to think if I could eliminate that call to [myURL p

Read the data into NSDate object, and compare it with timeIntervalSinceDate: method. This way, you'll get the time interval in seconds and then convert it to unit of days. Jesse Armand (http://jessearmand.com) On Sat, Sep 12, 2009 at 6:25 PM, Rajashekha
