All Code related to Part 1 of my series on Vaadin Grid

VaadinGrid-1.1.java

//This doesn't give you caption
Grid grid = new Grid();
 
// This creates a caption and can be seen on the top left corner of the grid
Grid grid  = new Grid("Basic");

VaadinGrid-1.2.java

//Add few columns followed by Data
grid.addColumn("name", String.class);
grid.addColumn("city", String.class);
grid.addColumn("pincode", String.class)
....
 
// Add some data rows
 
grid.addRow("Krishna", "Bangalore","560085");
grid.addRow("Anirudh", "Sindhanur","584128");
grid.addRow("Harin", "Bangalore","560027");
grid.addRow("Anil", "Vijayawada","520007");

VaadinGrid-1.3.java

/Initialize the container
BeanItemContainer<Person> container = new BeanItemContainer<Person>(Person.class);
container.add(new Person(1, "Krishna","Bangalore","560085");
container.add(new Person(2, "Anirudh", "Sindhanur","584128");
container.add(new Person(3, "Harin", "Bangalore","560027");
container.add(new Person(4, "Anil", "Vijayawada","520007");
 
//Add the container to the datasource
grid.setContainerDataSource(container);

VaadinGrid-1.4.java

grid.addSelectionListener(new SelectionListener() {
  @Override
 public void select(SelectionEvent event) {
     
 Set<Object> itemIDs = event.getSelected();
  
 //TODO do something with the items
  
 }
});

VaadinGrid-1.5.java

// From the above example, I wish to hide the PersonID, so I do the following
grid.removeColumn("personID");

VaadinGrid-1.6.java

// From the above Person example
grid.setColumnOrder("personName", "city", "pincode");

VaadinGrid-1.7.java

// Again from the Person example
// Get the Column object associated with the property
Column city = grid.getColumn("city");
// Set the Column Caption
city.setHeaderCaption("Person City");
