mvn jetty:run

This deploys demo at http://localhost:8080

Description

The Lookup field component allows you to search a specific record with:

• a combobox
• a dialog and a grid that can contains all the fields

How to use it

Create a new component LookupField and use it like a Field. The API is quite similar to a Vaadin Combobox.

Examples

Basic example with String

    public SimpleView() {
        LookupField<String> lookupField = new LookupField<>();
        List<String> items = Arrays.asList("item1","item2", "item3");
        lookupField.setDataProvider(DataProvider.ofCollection(items));
        lookupField.getGrid().addColumn(s -> s).setHeader("item");
        lookupField.setLabel("Item selector");
        add(lookupField);
    }

Basic example with an Object

    public PersonView() {
        LookupField<Person> lookupField = new LookupField<>(Person.class);
        List<Person> items = getItems();
        lookupField.setDataProvider(DataProvider.ofCollection(items));
        lookupField.setGridWidth("900px");
        lookupField.setHeader("Person Search");
        add(lookupField);
    }

    private List<Person> getItems() {
        PersonService personService = new PersonService();
        return personService.fetchAll();
    }

Internationalization

You can change the captions of the buttons, dialog header, serach label.

    public I18nView() {
        LookupField<String> lookupField = new LookupField<>();
        List<String> items = Arrays.asList("item1","item2", "item3");
        lookupField.setDataProvider(DataProvider.ofCollection(items));
        lookupField.getGrid().addColumn(s -> s).setHeader("item");
        // set the label of the field
        lookupField.setLabel("Item selector");
        //set the header text of the dialog
        lookupField.setHeader("utilisateurs");
        // translate the cpations of the component
        lookupField.setI18n(new LookupField.LookupFieldI18n()
            .setSearcharialabel("Cliquer pour ouvrir la fenêtre de recherche")
            .setSelect("Sélectionner")
            .setHeaderprefix("Recherche:")
            .setSearch("Recherche")
            .setHeaderpostfix("")
            .setCancel("Annuler"));
        add(lookupField);
    }
