    <p>I'm using HTML to style a cell inside JList -- it's a simple two-row table, where the second row has a non-default background. I want that row to span the whole width of the cell, instead of having it only as wide as the text inside it is.</p> <p>Here's an example:</p> <pre><code>import java.util.ArrayList; import javax.swing.JFrame; import javax.swing.JList; public class Example { public static void main(String[] args) { JFrame frame = new JFrame(); String html = "&lt;html&gt;"; html += "&lt;style type=\"text/css\"&gt;" + "body { margin: 0px auto; }\n" + "td { padding: 0px; margin: 0px; }\n" + "&lt;/style&gt;"; html += "&lt;body&gt;&lt;table&gt;"; html += "&lt;tr&gt;&lt;td&gt;line1&lt;/td&gt;&lt;/tr&gt;"; html += "&lt;tr&gt;&lt;td bgcolor=blue color=white&gt;line2&lt;/td&gt;&lt;/tr&gt;"; html += "&lt;body&gt;&lt;/table&gt;&lt;/html&gt;"; ArrayList&lt;String&gt; dataList = new ArrayList(); dataList.add(html); JList list = new JList(dataList.toArray()); frame.getContentPane().add(list); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.pack(); frame.setVisible(true); } } </code></pre> <p>"line2" has blue background, but only under the text. I want it to go all the way to the end of the window, essentially making the table (or row) width 100% of the cell width.</p> <p>I tried placing "width:100%" in various places, with no effect. The only thing that worked was setting the td {width...} to a specific pixel width, but then I'll need a custom cell renderer to change that width every time the window/component is resized... and it seems like there must be a simple html/css-only solution to this problem.</p>

    3. COThere seems to be a nice hole where all the documentation for using HTML in a JLabel should be. But, it really depends on how the renderer of the HTML is getting passed sizes. I'd be surprised if the default implementation signaled the HTML renderer every time the JLabel changed size. So... have fun with your custom renderer :)

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.
