Create a new Eclipse RCP project "de.vogella.databinding.person.swt" using the template "RCP application with a View". Add the plugin "de.vogella.databinding.person.model" as a dependency to your plugin. Also add the plugins "org.eclipse.core.databinding", "org.eclipse.core.databinding.beans", "org.eclipse.jface.databinding" and "org.eclipse.core.databinding.property" in the list of dependencies.

Change the class "View" to the following.

			
package de.vogella.databinding.person.swt;

import org.eclipse.core.databinding.Binding;

public class View extends ViewPart {
	public static final String ID = "de.vogella.databinding.person.swt.View";
	private Person person;

	private Text firstName;
	private Text ageText;
	private Button marriedButton;
	private Combo genderCombo;
	private Text countryText;

	@Override
	public void createPartControl(Composite parent) {

		person = new Person();
		Address address = new Address();
		address.setCountry("Deutschland");
		person.setAddress(address);
		person.setFirstName("John");
		person.setLastName("Doo");
		person.setGender("Male");
		person.setAge(12);
		person.setMarried(true);
		// Lets put thing to order
		Layout layout = new GridLayout(2, false);
		parent.setLayout(layout);

		Label firstLabel = new Label(parent, SWT.NONE);
		firstLabel.setText("Firstname: ");
		firstName = new Text(parent, SWT.BORDER);

		GridData gridData = new GridData();
		gridData.horizontalAlignment = SWT.FILL;
		gridData.grabExcessHorizontalSpace = true;
		firstName.setLayoutData(gridData);

		Label ageLabel = new Label(parent, SWT.NONE);
		ageLabel.setText("Age: ");
		ageText = new Text(parent, SWT.BORDER);

		gridData = new GridData();
		gridData.horizontalAlignment = SWT.FILL;
		gridData.grabExcessHorizontalSpace = true;
		ageText.setLayoutData(gridData);

		Label marriedLabel = new Label(parent, SWT.NONE);
		marriedLabel.setText("Married: ");
		marriedButton = new Button(parent, SWT.CHECK);

		Label genderLabel = new Label(parent, SWT.NONE);
		genderLabel.setText("Gender: ");
		genderCombo = new Combo(parent, SWT.NONE);
		genderCombo.add("Male");
		genderCombo.add("Female");

		Label countryLabel = new Label(parent, SWT.NONE);
		countryLabel.setText("Country");
		countryText = new Text(parent, SWT.BORDER);

		Button button1 = new Button(parent, SWT.PUSH);
		button1.setText("Write model");
		button1.addSelectionListener(new SelectionAdapter() {

			@Override
			public void widgetSelected(SelectionEvent e) {
				System.out.println("Firstname: " + person.getFirstName());
				System.out.println("Age " + person.getAge());
				System.out.println("Married: " + person.isMarried());
				System.out.println("Gender: " + person.getGender());
				System.out.println("Country: "
						+ person.getAddress().getCountry());
			}
		});

		Button button2 = new Button(parent, SWT.PUSH);
		button2.setText("Change model");
		button2.addSelectionListener(new SelectionAdapter() {
			@Override
			public void widgetSelected(SelectionEvent e) {
				person.setFirstName("Lars");
				person.setAge(person.getAge() + 1);
				person.setMarried(!person.isMarried());
				if (person.getGender().equals("Male")) {

				} else {
					person.setGender("Male");
				}
				if (person.getAddress().getCountry().equals("Deutschland")) {
					person.getAddress().setCountry("USA");
				} else {
					person.getAddress().setCountry("Deutschland");
				}
			}
		});

		// Now lets do the binding
		bindValues();
	}

	@Override
	public void setFocus() {
	}

	private void bindValues() {
		// The DataBindingContext object will manage the databindings
		// Lets bind it
		DataBindingContext bindingContext = new DataBindingContext();
		IObservableValue widgetValue = WidgetProperties.text(SWT.Modify)
				.observe(firstName);
		IObservableValue modelValue = BeanProperties.value(Person.class,
				"firstName").observe(person);
		bindingContext.bindValue(widgetValue, modelValue);

		widgetValue = WidgetProperties.text(SWT.Modify).observe(ageText);
		modelValue = BeanProperties.value(Person.class, "age").observe(person);

		// We want that age is a number
		IValidator numberValidator = new IValidator() {

			@Override
			public IStatus validate(Object value) {
				String s = String.valueOf(value);
				boolean matches = s.matches("\\d*");
				if (matches) {
					return ValidationStatus.ok();
				}
				return ValidationStatus.error("Only Number permitted");
			}
		};
		UpdateValueStrategy targetToModel = new UpdateValueStrategy();
		targetToModel.setAfterConvertValidator(numberValidator);

		bindingContext.bindValue(widgetValue, modelValue);

		widgetValue = WidgetProperties.selection().observe(marriedButton);
		modelValue = BeanProperties.value(Person.class, "married").observe(
				person);
		bindingContext.bindValue(widgetValue, modelValue);

		widgetValue = WidgetProperties.selection().observe(genderCombo);
		modelValue = BeansObservables.observeValue(person, "gender");

		bindingContext.bindValue(widgetValue, modelValue);

		// Address field is bound to the Ui
		widgetValue = WidgetProperties.text(SWT.Modify).observe(countryText);

		modelValue = BeanProperties.value(Person.class, "address.country")
				.observe(person);
		// Remember the bindingContext to allow control decoration
		Binding bindValue = bindingContext.bindValue(widgetValue, modelValue, targetToModel, null);
		ControlDecorationSupport.create(bindValue, SWT.TOP | SWT.RIGHT);
	}
}

		

Run the example and test it. Each time you change the UI element then model changes automatically. If you change the model then the UI will also update. We also demonstrate a validator and icon decorations for the field based on the result of the interface.
