Couldn't you read the file once during application startup, > Yes, there's a reason. The data fetched by the app is via a _relatively_ expensive network handshake with a remote service. The data returned is not much and hence I thought it better to write it the moment i receive it. There's a possibility that the app might be closed/crash due to some external factors and if I have it in memory (as a map) then I'd have to the network op all over again. -mandeep > store the data in a map and only write it out again when your > application terminates, provided anything has changed at all? > arne > > > _______________________________________________ > Interest mailing list > Interest@qt-project.org > http://lists.qt-project.org/mailman/listinfo/interest >
