How to respond to click on a table row in vaadin

Question

I've got the following code:

public Button getBtnSubmit(com.vaadin.ui.Button.ClickListener l) {
    if (null != l) {
        btnSubmit.addListener(l);
    }
    return btnSubmit;
}

public Table getTableCompany(HeaderClickListener hl) {
    if (null != hl) {
        tableCompany.addListener(hl);
    }
    return tableCompany;
}

I would like to add a listener that fires when I select a (different) row in the table.
This so that I can refresh some other controls with the table data, which listener should I use?

Solution 1

addListener is deprecated now. Use the following instead.

table.addItemClickListener(new ItemClickEvent.ItemClickListener() {
    @Override
    public void itemClick(ItemClickEvent itemClickEvent) {
        System.out.println(itemClickEvent.getItemId().toString());
    }
});

Solution 2

I would go for ItemClickListener:

 table.addListener(new ItemClickEvent.ItemClickListener() {

            @Override
            public void itemClick(ItemClickEvent event) {
               //implement your logic here
            }
        });

edit: For Vaadin 7+, use addItemClickListener method instead of addListener.

Solution 3

You want to add a ValueChangeListener

Solution 4

If you use the ValueChangeListener don't forget to set

  table.setImmediate(true);

This means that the browser will report a change on selection immediately. If you don't set this your listener is not called.

If you wish to get the id of the row clicked on then Integer value = (Integer) event.getItem().getItemProperty("id").getValue();

[ogzd]

what about event.getItemId() ?

[Patton]

I believe itemId is different from id, I am speaking about a column that is hidden and whose value is used for processing at the backend.

This is now deprecated ib Vaadin 7, the answer from Ishan Thilina Somasiri is the correct one
