    <p>I need to call the method a non static method <code>removeLocksOnExit()</code> from a ShutdownHook. the method is declared in te same class where the main is.</p> <p>In the main i have the following code:</p> <pre><code>//final Thread mainThread = Thread.currentThread(); Runtime.getRuntime().addShutdownHook(new Thread() { public void run() { // remove lock file... removeLocksOnExit(); } }); </code></pre> <p>The removeLocks() cannot be decared static and therefore i canot call it directly from the new thread.</p> <p>The main class contains However an action listners over the windows closing which calls the method as well. Here is an extract of the code:</p> <pre><code>addWindowListener(new WindowAdapter() { @Override public void windowClosing(WindowEvent e) { if (exit() == 0) { removeLocksOnExit(); log.info("END"); System.exit(0); } } }); </code></pre> <p>Perhaps i could then from the addShutdownHook fire the windows closing event. and this one will call the function fore me. ( Or create a special event for the purpose to be cached...</p> <p>Is it feasible?? If yes how would you fire the event??</p> <p>to have a better understanding here is the structure of my class:</p> <pre><code>public class IEPLC_Tool extends JFrame{ removeLocksOnExit(){ .... ... } public static void main(String[] args) { ............... ......... //final Thread mainThread = Thread.currentThread(); Runtime.getRuntime().addShutdownHook(new Thread() { public void run() { // remove lock file... removeLocksOnExit(); } }); } final IEPLC_Tool inst = new IEPLC_Tool(args); IEPLC_Tool(String[] args) { super(CustomPathModel.IEPLC_TITLE); setResizable(false); // FIXME find a way to auto size inner xml-editor addWindowListener(new WindowAdapter() { @Override public void windowClosing(WindowEvent e) { if (exit() == 0) { removeLocksOnExit(); log.info("END"); System.exit(0); } } }); setLookFeel(); initAdminStatus(); initGUI(); addFesaToolActionListener(this); } } </code></pre>

    1. COIf you can call the method from the anonymous inner class that gets invoked on the window closing event, then you can call it from the anonymous inner class that's invoked as part of the shutdown hook. What is the problem that makes you think you can't? Is it an exception?

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.
