    <p>I'm a bit desperate over here. I Have this jFrame and I need to close after I press Escape. This is easily done by using keyTyped Event. In the keyTyped event I tried to use System.exit which closes the window, but the process is still running in the task manager (and in the netbeans, even If I run from the jar file, it is still running in the task manager).</p> <p>I have tried dispose, setVisible(false) along with other things but nothing seems to work.</p> <p>EDIT:</p> <p>Code</p> <pre><code>public Sketch(int width, int height) { sketch = new JFrame(); area = new JLabel(); sketch.setUndecorated(true); sketch.setMinimumSize(new Dimension(width, height)); sketch.setSize(width, height); area.setBounds(0, 0, width, height); sketch.getContentPane().setLayout(null); sketch.getContentPane().add(area); sketch.pack(); sketch.setLocationRelativeTo(null); sketch.setVisible(true); sketch.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); imageBGR = new BufferedImage(width, height, BufferedImage.TYPE_3BYTE_BGR); imageGRAY = new BufferedImage(width, height, BufferedImage.TYPE_BYTE_GRAY); keyEvents(); setup(); Thread t = new Thread() { @Override public void run() { running=true; while(running) draw(); } }; t.start(); } private void keyEvents() { sketch.addKeyListener(new KeyAdapter() { @Override public void keyTyped(KeyEvent e) { if(e.getKeyChar()==KeyEvent.VK_ESCAPE) { running=false; System.exit(0); } } }); } </code></pre> <p>NOTE: The setup function is a blank function that I override when extending this class.</p> <p>EDIT2: SOLVED</p> <p>I found out what I was doing wrong. It appears that in the class that I was extended this one, I was using a webcam. When I call the System.exit function the webcam led is turned off, so I thought I didn't need to properly release it, but it was in fact needed. </p>

    3. COUpdated with my code. I have a process running, but I ensure it closes. I've searched the web for over 2 hours and still couldn't find anything that worked.

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.
