    <p>I have this code here that instance a JFrame with a simple animation, where you click the button and keeps running by using thread. I made an UI with a button that instances the JFrame, the problem is, when I click the button again and it instances another JFrame, the animation of the second one doesn't work properly. Even if I instance, like, 5 JFrames, all of the buttons to start the animation works only with the first JFrame. What I want to do is instance as much as I want to and all of them work separately. Here is the code of the class with the animation:</p> <pre><code>public class duduleo extends JFrame implements ActionListener, Runnable{ JButton imagens; int x=1; static ImageIcon icon[] = new ImageIcon[11]; static JLabel l; boolean anima=false; public static void main(String args[]){ JFrame janela = new duduleo(); janela.show(); } duduleo(){ icon[0]= new ImageIcon("duken1.jpg"); icon[1]= new ImageIcon("duken2.jpg"); icon[2]= new ImageIcon("duken3.jpg"); icon[3]= new ImageIcon("duken4.jpg"); icon[4]= new ImageIcon("duken5.jpg"); icon[5]= new ImageIcon("duken6.jpg"); icon[6]= new ImageIcon("duken7.jpg"); icon[7]= new ImageIcon("duken8.jpg"); icon[8]= new ImageIcon("duken9.jpg"); icon[9]= new ImageIcon("duken10.jpg"); icon[10]= new ImageIcon("duken11.jpg"); setSize(100,200); setLocation(200,150); getContentPane().setLayout(new GridLayout(2,1)); imagens = new JButton(icon[0]); l= new JLabel(icon[0]); imagens.addActionListener(this); getContentPane().add(l); getContentPane().add(imagens); } public void run(){ while(anima){ for(int i=0;i&lt;icon.length;i++){ l.setIcon(icon[i]); try{ Thread.sleep(100); }catch(Exception e){} }}} public void actionPerformed(ActionEvent e){ anima=!anima; Thread t; t = new Thread(this); t.start(); }} </code></pre> <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.
