It is probably because QFile/QTextStream are buffered so that your content 
does not get written to the disk exactly when you might expect but only when 
the buffer decides to flush itself or you do it explicitly. Simply try closing 
the file at the end of your function or call flush() to force the data to be 
written to disk. The buffering is there for performance reasons so that your 
app does not end up having to make many times more disk operations than are 
necessary.
