Lookup and Identify a Scene Element

[jtolotta]

The following creates a simple window displaying the following fields:

• proxyType (Combobox:enum)
• proxyHost (Textfield:String)
• proxyPort (Textfield:int
• proxyExclusions (Textfield:String)

The following Java code displays the content:

public class ProxyDemo extends Application {
    private FXForm<Proxy> fxForm;
    private StackPane mainPane = new StackPane();

    static enum ProxyType {
        DIRECT, HTTP, HTTPS, FTP, SOCKS;
    }

    static class Proxy {
        private final ObjectProperty<ProxyType> proxyType = new SimpleObjectProperty<ProxyType>();
        private final StringProperty proxyHost = new SimpleStringProperty();
        private final IntegerProperty proxyPort = new SimpleIntegerProperty();
        private final StringProperty proxyExclusions = new SimpleStringProperty();

        public Proxy(ProxyType proxyType, String proxyHost, int proxyPort, String proxyExclusions) {
            this.proxyType.set(proxyType);
            this.proxyHost.set(proxyHost);
            this.proxyPort.set(proxyPort);
            this.proxyExclusions.set(proxyExclusions);
        }

        public ProxyType getProxyType() {
            return proxyType.get();
        }

        public String getProxyHost() {
            return proxyHost.get();
        }

        public int getProxyPort() {
            return proxyPort.get();
        }

        public String getProxyExclusions() {
            return proxyExclusions.get();
        }
    }

    @SuppressWarnings("unchecked")
    @Override
    public void start(Stage primaryStage) throws Exception {
        Proxy proxy = new Proxy(ProxyType.DIRECT, "", 0, "");
        fxForm = new FXFormBuilder<>().source(proxy).build();

        mainPane.getChildren().addAll(fxForm);

        Scene root = new Scene(mainPane);

        primaryStage.setTitle("Demo");
        primaryStage.setScene(root);
        primaryStage.show();
    }

    public static void main(String... args) {
        ProxyDemo.launch(args);
    }
}

The following is my attempt to lookup the Proxy Type.

fxForm.getScene().lookup("#proxyType");

It is my intention to Disable the fields when the Proxy Type is DIRECT, otherwise enable them.

Is the "proxyType" a Combobox type?

What is the ID of this field that FXForm2 assigns?

How does FXForm2 assign the IDs?

You can access to the editor of the proxyType field using the #proxyType-form-editor id.

See this wiki page for more informations about classes and ids assigned to the form nodes.

Thanks that cleared this up.
