    1. COBy removing weighty from the JLabel, the anchor is now obsolete(ie, not doing anything). I see that this works, but when I add a third component using the same format as addressLine1 is breaks again so that the third component floats in the middle whilst the other two are right at the top.

    2. CO@RudiKershaw `PAGE_START` is equivalent to `NORTH` (in horizontal orientation), so it will be centered at the top. Since there is no extra vertical space, it will "only" center horizontally the component within its "cell". If you want all your components to be pushed to the top: either you use `weighty > 0` for the last component (and anchor it `NORTH`), either you add an extra component (transparent) with a `weighty > 0`. For a complete answer, please provide a complete question with the components you want and sketch of the layout you would like to achieve.

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.
