I looked a little bit today here with my application, and the term unresponsive for the Open Panel is not appropriate: it should be "stays open" when reading /processing the big data file and then the panel closes.
The main processing time is when converting date/time to NSTimeIntervalSince1970, and extracting data values..so a big ASCII data file can have > 500000 lines Simply put, the Open Panel should be closed, but it stays open until the data file has been processed and the data displayed as a graph. There should be a way to close NSDocument openPanel but didn't find anything about it… Any help is as always greatly appreciated :-) On 28 Jan 2013, at 18:44, Mike Abdullah wrote: > > On 28 Jan 2013, at 16:46, Gilles Celli <gilles.ce...@ecgs.lu> wrote: > >> Please don't be scared ;-) >> Well I'm little bit in a hurry … will look more closely tonight, but: >> >> What I've done til now is inside readFromURL:ofType:error: >> 1.
