    1. COOK. I read this before, and I didn't manage to put the code on my program. Not because it's wrong, but because I don't know how to do this using the netbeans "swing" editor. That code explains how to do it by invoking all the swing components (I mean, "writing" them). I had already done that! Using the design view. So when I try to invoke a swing component, it always throw a mistake I'm not able to solve

    2. CO@SebaPaz Mm i don't think you have to do it with the netbeans swing editor (also called matisse) cause you are doing anything with gui components. you have to code without the editor..

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.
