Binding a JCombobox using a buffered model?

[David Irwin]

All,

I'm using the JGoodies Binding framework in my Swing GUI to bind bean parameters to my visual display. In particular, I've created a JCombobox that I want to bind to bean parameter. I have several other parameters already bound using binding and a buffered model (i.e. someone can type a new value in a textfield but it doesn't actually make the changes to the bean's parameters until an action is triggered, like hitting an Apply button). It may be obvious, but is there a way to do the same, ie. buffer, with a JCombobox? Right now I have the following code:

        // sensor configuration
        config_tf = BasicComponentFactory.createTextField(presentationModel
            .getBufferedModel(HomenetHardware.PROPERTYNAME_CONFIGURATION), false);
        config_tf.setColumns(25);
        config_tf.setToolTipText("Hardware configuration");
 
                // sensor polling type
        polling_cb = BasicComponentFactory.createComboBox(
            presentationModel.getSelectionInList(), new PollingTypeListCellRenderer());

The first part (the config_tf textfield) creates a textfield buffered until the user triggers an action. But with the JCombobox I'm not sure how to do this. (the createComboBox only takes a selectionInList parameter).

Thanks for any hints.

Ah, I found the answer to be relatively straight forward. For everyone's benefit, I've posted the solution I found to work below:

        polling_cb = new JComboBox();
        polling_cb.setModel(new ComboBoxAdapter(presentationModel.getSelectionInList().getListModel(),
            presentationModel.getBufferedModel(Sensor.PROPERTYNAME_POLLINGTYPE)));
 
...more code...
 
private CustomPresentationModel(H hardware)
        {
            super(hardware);
 
            //selectionInList = new SelectionInList(hardware.getPollingTypeListModel(),
            //    getModel(Sensor.PROPERTYNAME_POLLINGTYPE));
 
            selectionInList = new SelectionInList(hardware.getPollingTypeListModel());
        }

and in my hardware object I have the following:

 private ObservableList pollingTypeListModel;
 
... more code...
 
        // initialize binding information
        pollingTypeListModel = new ArrayListModel();
        PollingService.PollingTypes[] pollingTypes = PollingService.PollingTypes.values();
 
        for (int i = 0; i < pollingTypes.length; i++)
        {
            pollingTypeListModel.add(pollingTypes[i]);
        }
