Getting Further with Spring RCP

Creating a Table

Let's now display our data in a table.

First, we create the table, using the Spring RCP "AbstractObjectTable" class. This is a convenience class provided by Spring RCP, with some handy methods for setting up our table in an intuitive manner, providing a simple layer between our domain and our view.

Then we add the related messages to the messages.properties file.

And, finally, we add the table to the CustomerView.

So, let's start by creating a new class called "CustomerTable", with this content:

package simple;

import javax.swing.JTable;
import javax.swing.table.TableColumnModel;

import domain.CustomerDataStore;
import org.springframework.richclient.table.support.AbstractObjectTable;

public class CustomerTable extends AbstractObjectTable {

    private CustomerDataStore dataStore;

    public CustomerTable(CustomerDataStore dataStore) {
        super("customers", new String[]{
            "lastName", 
            "firstName", 
            "address.street", 
            "address.city", 
            "address.state", 
            "address.zip"});
        this.dataStore = dataStore;
    }

    @Override
    protected void configureTable(JTable table) {
        TableColumnModel tcm = table.getColumnModel();
        tcm.getColumn(0).setPreferredWidth(100);
        tcm.getColumn(1).setPreferredWidth(100);
        tcm.getColumn(2).setPreferredWidth(200);
        tcm.getColumn(3).setPreferredWidth(50);
        tcm.getColumn(4).setPreferredWidth(10);
        tcm.getColumn(5).setPreferredWidth(50);
    }

    @Override
    protected Object[] getDefaultInitialData() {
        return dataStore.getAllCustomers();
    }

}

Next, add the strings referred to above to the messages.properties file, with values that will be displayed as the labels of the columns in the table:

firstName.label=First Name
lastName.label=Last Name
address.street.label=Street
address.city.label=City
address.state.label=State
address.zip.label=Zip

And then we display the table in our CustomerView, the same CustomerView that we had at the end of the 2nd part of "Getting Started with Spring RCP". We first need a getter and a setter for the data store that we registered in the richclient-application-context.xml and then we need to override AbstractView.createControl() to return a JComponent that consists of our AbstractObjectTable within a JPanel:

package simple;

import domain.CustomerDataStore;
import java.awt.BorderLayout;
import javax.swing.JComponent;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import org.springframework.richclient.application.support.AbstractView;

public class CustomerView extends AbstractView {

    private CustomerDataStore customerDataStore;
    private CustomerTable customerTable;

    protected CustomerDataStore getCustomerDataStore() {
        return customerDataStore;
    }

    public void setCustomerDataStore(CustomerDataStore customerDataStore) {
        this.customerDataStore = customerDataStore;
    }

    @Override
    protected JComponent createControl() {
        
        customerTable = new customerTableFactory().createCustomerTable();
        JPanel view = new JPanel(new BorderLayout());
        JScrollPane sp = getComponentFactory().createScrollPane(customerTable.getControl());
        view.add(sp, BorderLayout.CENTER);
        return view;
        
    }

    private class customerTableFactory {

        public CustomerTable createCustomerTable() {
            
            CustomerTable customerTable = new CustomerTable(customerDataStore);
            return customerTable;
            
        }
        
    }
 
}

Now deployment will result in our table being displayed in the CustomerView:
