    <p>Am trying to get my program to update the progress bar values constantly within a method while performing some operations. However this does not happen until the end, and the UI freezes. </p> <p>After looking around to similar questions with my problems, I tried to implement the accepted solutions (Using threads) however I cannot get it to work correctly. Is just like if they where not there.</p> <p>My program contains several classes, the <code>Main</code> being the one automatically created by netbeans on the JFrame <em>Design</em> mode, so there are certain things such as the <code>static void main</code> and the <code>public Main</code> that am not really sure of some of its contents. Under i will put the snippets of those methods, together with my thread implementation.</p> <pre><code>public class Main extends javax.swing.JFrame implements ActionListener, Runnable{ // I added implements ActLis, Runn..... ... static Main _this; // I included this variable ... public static void main(String args[]) { Main m = new Main(); // Added by me new Thread(m).start(); // Added by me java.awt.EventQueue.invokeLater(new Runnable() { public void run() { new Main().setVisible(true); } }); } ... public Main() { initComponents(); _this = this; // Added by me } ... // I also included these 2 methods in the class public void actionPerformed(ActionEvent e) { synchronized(this){ notifyAll(); } } public void run() { try{synchronized(this){wait();}} catch (InterruptedException e){} progressBar.setValue(50); } ... private void buttonPressed(java.awt.event.MouseEvent evt) { for(int i=0; i&lt;=100; i++) { for(int j=0; j&lt;=5; j++) { // does some work } run(); } } </code></pre> <p>All the things that I commented as <code>I added...</code> are things that I putted according to tutorials and answers I have seen online, but nothing seems to work and it feels like I have tried close to a million different combinations... </p> <p>Thanks in advance for helping out.</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.
