Then, when i click a row in semester table, the result table will update it's data.</p> <p>I can do it from student table to semester table with listselectionlistener and overriding valueChanged method. But how should i do for the same for semester table to result table? I'm getting stuck on this...</p> <ul> <li>i use database to retrieve all values to jtable -</li> </ul> <p>edited : now I used SwingWorker, but i have another problem :</p> <ol> <li>When the UI is showing, the master table display a row (this is true)</li> <li>When i try to clicked that row, it dont clicked, i mean usually u will get a background in a selected row, but not with me (wrong->my problem)</li> <li>It also throw NullPointerException at my child table</li> <li>But when i wait for a while, it suddenly work again...</li> </ol> <p>i've uploaded my sample code, and remove unrelated code here <a href="http://dl.dropbox.com/u/67181952/mycode.java" rel="nofollow">http://dl.dropbox.com/u/67181952/mycode.java</a></p> <p>2nd code for error in child table <a href="http://dl.dropbox.com/u/67181952/spk.java" rel="nofollow">http://dl.dropbox.com/u/67181952/spk.java</a></p> <p>I hope i explained well, sorry for my bad english.</p> <p>Thanks for any help :)</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.
