Use the random library: <pre><code>import java.util.Random; </code></pre> Then create a random generator: <pre><code>Random rand = new Random(); </code></pre> As colours are separated into red green and blue, you can create a new random colour by creating random primary colours: <pre><code>// Java 'Color' class takes 3 floats, from 0 to 1. float r = rand.nextFloat(); float g = rand.nextFloat(); float b = rand.nextFloat(); </code></pre> Then to finally create the colour, pass the primary colours into the constructor: <pre><code>Color randomColor = new Color(r, g, b); </code></pre> <hr> You can also create different random effects using this method, such as creating random colours with more emphasis on certain colours ... pass in less green and blue to produce a "pinker" random colour. <pre><code>// Will produce a random colour with more red in it (usually "pink-ish") float r = rand.nextFloat(); float g = rand.nextFloat() / 2f; float b = rand.nextFloat() / 2f; </code></pre> Or to ensure that only "light" colours are generated, you can generate colours that are always > 0.5 of each colour element: <pre><code>// Will produce only bright / light colours: float r = rand.nextFloat() / 2f + 0.5; float g = rand.nextFloat() / 2f + 0.5; float b = rand.nextFloat() / 2f + 0.5; </code></pre> There are various other colour functions that can be used with the <code>Color</code> class, such as making the colour brighter: <pre><code>randomColor.brighter(); </code></pre> An overview of the <code>Color</code> class can be read here: <a href="http://download.oracle.com/javase/6/docs/api/java/awt/Color.html" rel="noreferrer">http://download.oracle.com/javase/6/docs/api/java/awt/Color.html</a>

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.
