    1. COSomehow, your code lost all indentation when copy-pasting it from your IDE. It would be far easier to read if you could correct this. There also has to be something missing. `# endif` is just stuck in there randomly, without an `#if`.

    2. COTo be allowed to use a const declared object's functions, it's functions must be declared as const as well, or the compiler won't know if the functions will alter the const object. I recommend reading Const Correctness [link](http://www.parashift.com/c++-faq-lite/const-correctness.html) on the C++ FAQ site.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
