Netbeans: How do I add a valueChanged listener to a JTable from the "design" GUI builder?

java, jtable, netbeans, netbeans-7, swing

Solution

You can create your own `ListSelectionListener` in the editable part of the source. You can add an instance of the listener to the selection model of the class variable `jTable1` in your table's `Post-init Code` property:

jTable1.getSelectionModel().addListSelectionListener(new MyListener());

The listener itself might look like this:

private static class MyListener implements ListSelectionListener {

    @Override
    public void valueChanged(ListSelectionEvent e) {
        System.out.println(e.getFirstIndex());
    }
}

Problem

I right clicked the JTable and inserted some code into "post listeners code" in an awful kludge. I don't see an option to add ``` table.getSelectionModel().addListSelectionListener(new ListSelectionListener() { public void valueChanged(ListSelectionEvent evt) { ``` to "events" in the "design" view for the JTable. I'm sure there's a way to add a valueChanged(ListSelectionEvent evt) from design view, but how? maybe it's a bug? Row selection change events are produced by ListSelectionModel of JTable, not by JTable itself - so the event cannot be presented in Component Inspector (as event of JTable). Handling this event must be done manually, e.g. like: ``` jTable1.getSelectionModel().addListSelectionListener( new javax.swing.event.ListSelectionListener() { public void valueChanged(ListSelectionEvent evt) { customRowSelectionEventHandler(evt); } } ); ``` Although maybe there's a way to get the ListSelectionModel for a JTable outside of the "blue", "managed," code?
