    <p>To answer your first question:</p> <ul> <li>Most dynamic languages have their <code>method_missing</code> constructs, PHP has a <a href="http://php.net/manual/en/language.oop5.magic.php" rel="nofollow noreferrer">magic methods</a> (<code>__call</code> and <code>__callStatic</code>) and Python has <code>__getattr__</code>. I think the reason this isn't available in C++ that it goes against the typed nature of C++. Implementing this on a class means that any typos will end up calling this function (at runtime!), which prevents catching these problems at compile time. Mixing C++ with duck typing doesn't seem to be a good idea. </li> <li>C++ tries to be as fast as possible, so first class functions are out of question.</li> <li>AOP. Now this is more interesting, techincally there's nothing that prevents this being added to the C++ standard (apart from the fact that adding another layer of complexity to an already extremly complex standard is might not be a good idea). In fact there are compilers which are able to wave code, <a href="http://www.aspectc.org/" rel="nofollow noreferrer">AspectC++</a> is one of them. A year ago or so it wasn't stable but it looks like since then their managed to release 1.0 with a pretty decent test suite so it might does the job now.</li> </ul> <p>There are a couple of techniques, here's a related question:</p> <p><a href="https://stackoverflow.com/questions/6622290/emulating-clos-before-after-and-around-in-c/6622774">Emulating CLOS :before, :after, and :around in C++</a>.</p>

    1. COThanks, AspectC++ seems to provide what I ask for. Requiring a custom compiler for this language extension is a bit scary though :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
