    1. CO+1 good one. I was actually writing my answer as well but I got annoyed on the [problem that I describe here](http://stackoverflow.com/questions/6072956/how-to-correct-center-gridlayout-using-standard-java-layout-managers) can you @mKorbel do something about that?

    2. COThank you. My primary problems are still not solved, though. 1. How do I make the buttons a fixed size, say 25x25, and still keep the compartment size the same? button.setSize(25, 25) has no effect at all. 2. How do I set the red area's height to `0.05 * frame.getHeight()`, for example? If I do this in the constructor, the red area will not be resized when resizing the window.

    3. COagreed, then easiest way is use GrigBagLaout (for childs JPanels) and check this examples http://www.java2s.com/Tutorial/Java/0240__Swing/1480__GridBagConstraints.htm how you can really stick (f.e JButton) in JPanel with constraints.anchor = GridBagConstraints.CENTER;

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.

SQuiL has stopped working due to an internal error.

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