    <blockquote> <p>I am using a <code>JList</code>, and due to the <code>JList</code> not have a (value,text) (so I can display text and use the value in my code)</p> </blockquote> <p>It's really hard to understand your problem, but I "suspect" for the quoted line that you have a missunderstanding between <code>JList</code> model and text displayed by the <code>JList</code> itself. I think that's why you have a separate <code>List</code>.</p> <p>The model can contain any object you want and the <code>JList</code> can also display a text as you want regardless the object itself. This last task is done by a <a href="http://docs.oracle.com/javase/7/docs/api/javax/swing/ListCellRenderer.html" rel="nofollow noreferrer">ListCellRenderer</a>. Take a look to <a href="http://docs.oracle.com/javase/tutorial/uiswing/components/list.html#renderer" rel="nofollow noreferrer">Writing a Custom Cell Renderer</a></p> <p>For instance you can have this class:</p> <pre><code>class Person { String lastName; String name; public Person(String lastName, String name){ this.lastName = lastName; this.name = name; } public String getLastName(){ return this.lastName; } public String getName(){ return this.name; } } </code></pre> <p>Now you want your <code>JList</code> keep <code>Person</code> objects to work with them later. This part is easy just create a <code>ListModel</code> and add elements into it:</p> <pre><code>DefaultListModel model = new DefaultListModel(); model.addElement(new Person("Lennon","John")); model.addElement(new Person("Harrison","George")); model.addElement(new Person("McCartney","Paul")); model.addElement(new Person("Starr","Ringo")); </code></pre> <p>But you want to display the name and last name of each <code>Person</code>. Well you can implement your own <code>ListCellRenderer</code> to do this:</p> <pre><code>JList list = new JList(model); list.setCellRenderer(new DefaultListCellRenderer(){ @Override public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus); if(value instanceof Person){ Person person = (Person)value; setText(person.getName() + " " + person.getLastName()); } return this; } }); </code></pre> <p>And your <code>JList</code> will show the items as you want:</p> <p><img src="https://i.stack.imgur.com/LcX2J.jpg" alt="enter image description here"> </p>

    3. COAlright then, I wasn't that lost :P Following the example: 1) In your `ListCellRenderer` make this: `setText(person.getName())`. 2) Assuming you have a method like `saveFile(String fileName)` you can do this: `saveFile(((Person)list.getSelectedValue()).getLastName())`. As `list`'s model contains `Person` objects you can cast the selected value as such and work with it as needed. @EsmaeelQash

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.
