    <p>I have this class, let's say, <code>Foo</code>. It <code>extends JFrame</code> and is a singleton. That being said, it has two <strong>static fields</strong>: 1) an instance of <code>Foo</code> and 2) a <code>Color</code>.</p> <p><strong>Here's a code snippet of <code>Foo</code>:</strong> </p> <pre><code>public class Foo extends JFrame{ private static final Color FOO_RED = new Color(155, 64, 69); private static final Foo INSTANCE = new Foo(); private Foo(){ //do stuff } public static Foo getInstance(){ return INSTANCE; } } </code></pre> <p>I also have another class, let's say, <code>Launcher</code>. This is the <strong>main class</strong> that is responsible for launching the application. It's a simple class in that its only job is to delegate the task of constructing <code>Foo</code> to the <code>EDT</code>.</p> <p><strong>Here's a code snippet of <code>Launcher</code>:</strong></p> <pre><code>public class Launcher{ public static void main(String[] args){ SwingUtilities.invokeLater((new Runnable(){ @Override public void run() { Foo.getInstance(); } })); } } </code></pre> <p>Now, this all works just fine. <strong>But</strong>, when I switch the ordering of <code>Foo</code>'s fields (<strong>See below</strong>), the components that use <code>FOO_RED</code> are no longer painted this color. </p> <pre><code>public class Foo extends JFrame{ private static final Foo INSTANCE = new Foo(); //declared before Color private static final Color FOO_RED = new Color(155, 64, 69); private Foo(){ //do stuff } public static Foo getInstance(){ return INSTANCE; } } </code></pre> <p>So, this begs the question, does the ordering of <strong>static fields</strong> matter when it comes to <code>Swing</code>?</p>

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.
