Definition: When user use button ENTER so then pointer will be focus to the next component for the example JTextField. For this requirement we have to make a custom JTextField binder. You can find code below:

import java.awt.event.KeyAdapter;

import java.awt.event.KeyEvent;

import java.beans.PropertyChangeEvent;

import java.beans.PropertyChangeListener;

import java.util.Map;

import javax.swing.JComponent;

import javax.swing.JTextField;

import org.springframework.binding.form.FormModel;

import org.springframework.richclient.form.binding.Binding;

import org.springframework.richclient.form.binding.support.AbstractBinder;

import org.springframework.richclient.form.binding.support.CustomBinding;

public class CTextFieldBinder extends AbstractBinder {

. ……

protected Binding doBind(JComponent control, FormModel formModel,     java.lang.String formPropertyPath, Map context) {

final JTextField textField = (JTextField)control;

// TODO Auto-generated method stub

return new CustomBinding(formModel, formPropertyPath, java.lang.String.class){

@Override

protected void valueModelChanged(Object text) {

// TODO Auto-generated method stub

textField.setText(text.toString());

textField.validate();

}

@Override

protected JComponent doBindControl() {

// TODO Auto-generated method stub

textField.addPropertyChangeListener(null,new PropertyChangeListener() {

public void propertyChange(PropertyChangeEvent evt) {

super.toString();

controlValueChanged(textField.getText());

}

});

textField.addKeyListener(new KeyAdapter(){@Override

public void keyPressed(KeyEvent e) {

controlValueChanged(textField.getText());

int key = e.getKeyCode();

if (key==KeyEvent.VK_ENTER){

textField.transferFocus();

}

}

});

return textField;

}

}

}

In that binder just add a key listener to recognize what button the user press. After that, register the binder in the binder strategy;

<bean id=“binderSelectionStrategy” class=“org.springframework.richclient.form.binding.swing.SwingBinderSelectionStrategy”>

<property name=“bindersForPropertyTypes”>

<map>

<entry>

<key><value type=“java.lang.Class”>java.lang.String</value></key>

<bean class=“com.simiantech.simone.domain.custom.CTextFieldBinder” />

</entry>

</property>

<bean/>

Make a validation form to submit data customer with properties name, lastname and address.

Before submit the form user must fill the name without number and with minimal character,

lastname must be filled and address must be filled too.

1. We have customer class code below:
   

   import java.util.Date;

   public class Customer {

   private String name;

   private String lastame;

   private Branch address;

   public String getCustomerName() {

   return name;

   }

   public void setCustomerName(String name) {

   this.name = name;

   }

   public String getCustomerLastName() {

   return name;

   }

   public void setCustomerLastName(String name) {

   this.name = name;

   }

   public Address getAddress() {

   return address;

   }

   public void setAddress(Address address) {

   this.address = address;

   }

   }

2. Make a class implement DefaultRulesSource(org.springframework.rules.support.DefaultRulesSource) . For example class ApplicationRule.

   import org.springframework.rules.Rules;

   import org.springframework.rules.constraint.Constraint;

   import org.springframework.rules.support.DefaultRulesSource;

   import com.simiantech.simba.model.Customer;

   public class ApplicationRule extends DefaultRulesSource{

   private final Constraint NAME_CONSTRAINT = all(new Constraint[]{required(), minLength(2),

   regexp(“[-'.a-zA-Z ]*”, “alphabeticConstraint”)

   });

   private ApplicationRule(){

   super();

   addRules(createCustomerRules());

   }

   private Rules createCustomerRules(){

   return new Rules(Customer.class){

   protected void initRules(){

   add(“name”, NAME_CONSTRAINT);

   add(“lastname”, required());

   add(“address”,required());

   }

   };

   }

   }

3. Register ApplicationRule class in the richclient-application-context.xml. Anywhere within that file, add the following:


   <bean id=“rulesSource” class=“com.simiantech.simba.teller.domain.rule.ApplicationRule” /

4. Add rulesource bean to be an property in the application service in richclient-application-context.xml file below:


   <bean id=“applicationServices” class=“org.springframework.richclient.application.support.DefaultApplicationServices”>

   <property

   … ….

   </property>

   <property name=“rulesSourceId”>

   <idref bean=“rulesSource”/>

   </property>

   </bean>

5. Make customer form
   

   import java.util.List;

   import javax.swing.JComponent;

   import org.springframework.binding.form.FormModel;

   import org.springframework.richclient.form.AbstractForm;

   import org.springframework.richclient.form.builder.FormLayoutFormBuilder;

   public class CustomerForm extends AbstractForm {

   public CustomerForm(final FormModel formModel) {

   super(formModel);

   setId(“customer”);

   }

   @Override

   protected JComponent createFormControl() {

   FormLayout layout = new FormLayout(“right:pref, $rgap, fill:pref:grow, “default”);

   FormLayoutFormBuilder builder = new FormLayoutFormBuilder(getBindingFactory(), layout);

   builder.setLabelAttributes(“r, c”);

   builder.addPropertyAndLabel(“name “);

   builder.nextRow();

   builder.addPropertyAndLabel(“lastname”);

   builder.nextRow();

   builder.addPropertyAndLabel(“address”);

   return builder.getPanel();

   }

   }

6. Make customer View
   

   import java.awt.BorderLayout;

   import java.util.List;

   import javax.swing.JComponent;

   import javax.swing.JPanel;

   import org.springframework.binding.form.ValidatingFormModel;

   import org.springframework.richclient.application.support.AbstractView;

   import org.springframework.richclient.dialog.DialogPage;

   import org.springframework.richclient.dialog.TitledPageApplicationDialog;

   import org.springframework.richclient.form.FormModelHelper;

   public class CustomerView extends AbstractView {

   private CustomerForm customerForm;

   public void setCustomerForm(CustomerForm customerForm) {

   this.customerForm = customerForm;

   }

   @Override

   public JComponent createControl() {

   JPanel view = new JPanel(new BorderLayout());

   ValidatingFormModel model = FormModelHelper.createFormModel(New Customer());

   CompositeDialogPage composite = new CompositeDialogPage(“form”) {

   protected boolean onFinish() {

   return true;

   }

   };

   customerForm = new CustomerForm(model);

   tabbedPane = new TabbedDialogPage(“myCustomer”);

   DialogPage page1 = composite.addForm(customerForm,“customer”);

   tabbedPane.addPage(page1);

   TitledPageApplicationDialog dialog = new TitledPageApplicationDialog(tabbedPane, getWindowControl()) {

   protected boolean onFinish() {

   return true;

   }

   };

   view.add(dialog.getDialog().getContentPane(), BorderLayout.CENTER);

   return view;

   }

   }
