Hello Vaadin Lovers! -_-
This is the continuation of this threat:
Thread whit steps for Chapter 3
.
This is the structure of this threat:
[b]
1 - Goal for
Chapter 4
(link)
2 - Step by Step
3 -
QUESTIONS
[/b]
(for “Advanced Users” if they have time to explain us “why” or if they can apport some source where it explains this questions.)
1 - Goal for chapter 4
2 - Step by Step
Step 1:
So let´s copy this code from
Chapter 4
package com.vaadin.demo.tutorial.addressbook.data;
import java.io.Serializable;
public class Person implements Serializable {
private String firstName = "";
private String lastName = "";
private String email = "";
private String phoneNumber = "";
private String streetAddress = "";
private Integer postalCode = null;
private String city = "";
// + setters and getters for all fields
}
Step 2:
And we paste it on “Project Explorer” / SRC
Step 3:
And we get a new file called “Person.java”
Step 4:
We select the new file. And press ALT + SHIFT + S and apears this dialog.
Step 5:
We select all the “Checkboxes” and OK
Step 6:
This is how it looks the code automatically created.
Step 7:
Now we create a new “Package”. We take this pece of code “Source 30” from here
Chapter 4.3
package com.vaadin.demo.tutorial.addressbook.data;
import java.io.Serializable;
import com.vaadin.data.util.BeanItemContainer;
public class PersonContainer extends BeanItemContainer<Person> implements
Serializable {
public PersonContainer() throws InstantiationException,
IllegalAccessException {
super(Person.class);
}
}
Step 8:
We paste it on the “Project Explorer”.
Step 9:
This is how it looks inside the new file created “PersonContainer.java”
Step 10:
Now we copy this code.
public static final Object[] NATURAL_COL_ORDER = new Object[]
{
"firstName", "lastName", "email", "phoneNumber", "streetAddress",
"postalCode", "city" };
public static final String[] COL_HEADERS_ENGLISH = new String[]
{
"First name", "Last name", "Email", "Phone number",
"Street Address", "Postal Code", "City" };
Step 11:
And paste it inside “PersonContainer.java” file
Step 12:
This is how it looks once it´s pasted.
Step 13:
Now we copy this code “Source 31”
public static PersonContainer createWithTestData() {
final String[] fnames = { "Peter", "Alice", "Joshua", "Mike", "Olivia",
"Nina", "Alex", "Rita", "Dan", "Umberto", "Henrik", "Rene",
"Lisa", "Marge" };
final String[] lnames = { "Smith", "Gordon", "Simpson", "Brown",
"Clavel", "Simons", "Verne", "Scott", "Allison", "Gates",
"Rowling", "Barks", "Ross", "Schneider", "Tate" };
final String cities[] = { "Amsterdam", "Berlin", "Helsinki",
"Hong Kong", "London", "Luxemburg", "New York", "Oslo",
"Paris", "Rome", "Stockholm", "Tokyo", "Turku" };
final String streets[] = { "4215 Blandit Av.", "452-8121 Sem Ave",
"279-4475 Tellus Road", "4062 Libero. Av.", "7081 Pede. Ave",
"6800 Aliquet St.", "P.O. Box 298, 9401 Mauris St.",
"161-7279 Augue Ave", "P.O. Box 496, 1390 Sagittis. Rd.",
"448-8295 Mi Avenue", "6419 Non Av.",
"659-2538 Elementum Street", "2205 Quis St.",
"252-5213 Tincidunt St.", "P.O. Box 175, 4049 Adipiscing Rd.",
"3217 Nam Ave", "P.O. Box 859, 7661 Auctor St.",
"2873 Nonummy Av.", "7342 Mi, Avenue",
"539-3914 Dignissim. Rd.", "539-3675 Magna Avenue",
"Ap #357-5640 Pharetra Avenue", "416-2983 Posuere Rd.",
"141-1287 Adipiscing Avenue", "Ap #781-3145 Gravida St.",
"6897 Suscipit Rd.", "8336 Purus Avenue", "2603 Bibendum. Av.",
"2870 Vestibulum St.", "Ap #722 Aenean Avenue",
"446-968 Augue Ave", "1141 Ultricies Street",
"Ap #992-5769 Nunc Street", "6690 Porttitor Avenue",
"Ap #105-1700 Risus Street",
"P.O. Box 532, 3225 Lacus. Avenue", "736 Metus Street",
"414-1417 Fringilla Street", "Ap #183-928 Scelerisque Road",
"561-9262 Iaculis Avenue" };
PersonContainer c = null;
Random r = new Random(0);
try {
c = new PersonContainer();
for (int i = 0; i < 100; i++) {
Person p = new Person();
p.setFirstName(fnames[r.nextInt(fnames.length)]
);
p.setLastName(lnames[r.nextInt(lnames.length)]
);
p.setCity(cities[r.nextInt(cities.length)]
);
p.setEmail(p.getFirstName().toLowerCase() + "."
+ p.getLastName().toLowerCase() + "@vaadin.com");
p.setPhoneNumber("+358 02 555 " + r.nextInt(10) + r.nextInt(10)
+ r.nextInt(10) + r.nextInt(10));
int n = r.nextInt(100000);
if (n < 10000) {
n += 10000;
}
p.setPostalCode(n);
p.setStreetAddress(streets[r.nextInt(streets.length)]
);
c.addItem(p);
}
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return c;
}
}
Step 14:
And we paste it inside “PersonContainer.java” right here.
Step 15:
This is how it looks after we paste it.
Step 16:
Now we copy this code. “Source 32” from
Chapter 4.4
private PersonContainer dataSource = PersonContainer.createWithTestData();
Step 17:
And paste it inside “AddressbookApplication.java”
Step 18:
This is how it looks once pasted
Step 19:
Now we copy “Source 33” from
Chapter 4.4
public PersonContainer getDataSource() {
return dataSource;
}
Step 20:
And we paste it right here.
Step 21:
This is how it looks once paste it.
Step 22:
Now we copy this “Source 34” from
Chapter 4.4
public PersonList(AddressBookApplication app) {
setSizeFull();
setContainerDataSource(app.getDataSource());
setVisibleColumns(PersonContainer.NATURAL_COL_ORDER);
setColumnHeaders(PersonContainer.COL_HEADERS_ENGLISH);
}
Step 23:
And paste it over the this code inside “PersonList.java” and replace it with this one.
Step 24:
This is how it looks once paste it.
Step 25:
Now we move inside “AddressbookAplication.java” And search after this pece of code.
Step 26:
We click again over the code until we see this dialog. And click over IMPORT
Step 27:
Now we move on the same file “AddressbookApplication.java” until “Source 9” right here
Step 28:
And we add “this” inside the ( ).
Step 29:
And that´s all! Now we gonna just “Run on Server” and check after the result!
Step 30:
Just Finish button
Step 31:
And here we go!! PERFECT!! :lol:
