    1. CODon't forget to `g2d.dispose()`. Also, I was pondering how you end up with an `Image` as opposed to a `BufferedImage` in `scaleImage(int w, int h, Image img)` - the reason being I'd tend to `bi = new BufferedImage(w, h, img.getType());` (not possible with an `Image`).

    2. CO@AndrewThompson aah yes `dispose()` I always forget that.. Whats the difference if i omit the call or not? And thank you I forget at 1 stage I had changed Image to `BufferedImage` but not in the example I had above :). and +1 for `img.getType()`.

    3. COBasically, a `Graphics` instance is apparently a sizable chunk of memory. So if we create a `Graphics`, best to dispose of it as soon as it is done with. I think @trashgod was better at explaining it..

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.
