Hi, I searched the mailing-list but didn't find an answer….so sorry if this was posted before:
I've setup a document based application which can read large ASCII data files (>150MB). When opening the document the method readFromURL:ofType:error is used which then opens a small feedback window showing the file name and an animated progress bar with a "Cancel" NSButton. Simple question: How do I cancel the document when it is loading the data (sometimes it can take 10 seconds or more to load the data) if a user clicks the Cancel button ? Should I create an IBAction which generates an NSError ? But how does readFromURL:ofType:error get this error message (should I use a delegate ?) Any clue is greatly appreciated.
