Hello, I've been hacking a bit and, using the pytime DataEngine as an example, successfully built a "dummy" Python DataEngine that fetches records from NCBI on a hard-coded query and sets data correctly. I admit it was surprisingly easy to set up.
Although my knowledge of C++ is zero, I have been reading some of the API and the tutorials on TechBase, to tackle the next big question: how to make the source retrieval dependent on an "external" input, e.g. that would come from the future applet interface. Let's make an example to make things clearer. A user may want to search for the term "foo", and another for the term "bar", and of course, they would get different results. How can I make the DataEngine aware that the query parameter should be "foo" in one case, and "bar" in the other? I have been reading the description of DataContainer to see (as per previous suggestion) about subclassing it, but I still didn't find very clear *if* the thing I'm looking for is doable with the current API. Apologies for the message if it's somewhat stupid (I admit I don't have a big programming experience - all my past work has been, with few exceptions, confined to file manipulation).
