Examples with PropertyChangeListener com.vaadin.flow.dom.PropertyChangeListener used on opensource projects

Example 1 with PropertyChangeListener

use of com.vaadin.flow.dom.PropertyChangeListener in project flow by vaadin.

the class ElementPropertyMapTest method listenerIsNotified.

private void listenerIsNotified(boolean clientEvent) {
    ElementPropertyMap map = createSimplePropertyMap();
    StateNode node = map.getNode();
    AtomicReference<PropertyChangeEvent> event = new AtomicReference<>();
    PropertyChangeListener listener = ev -> {
        Assert.assertNull(event.get());
        event.set(ev);
    };
    map.addPropertyChangeListener("foo", listener);
    map.setProperty("foo", "bar", !clientEvent);
    Assert.assertNull(event.get().getOldValue());
    Assert.assertEquals("bar", event.get().getValue());
    Assert.assertEquals("foo", event.get().getPropertyName());
    Assert.assertEquals(Element.get(node), event.get().getSource());
    Assert.assertEquals(clientEvent, event.get().isUserOriginated());
    // listener is not called. Otherwise its assertion fails.
    map.setProperty("bar", "foo");
}

Example 2 with PropertyChangeListener

use of com.vaadin.flow.dom.PropertyChangeListener in project flow by vaadin.

the class ElementPropertyMapTest method removePropertyChangeListener_fireEvent_listenerIsNotNotified.

@Test
public void removePropertyChangeListener_fireEvent_listenerIsNotNotified() {
    ElementPropertyMap map = createSimplePropertyMap();
    PropertyChangeListener listener = ev -> {
        Assert.fail();
    };
    Registration registration = map.addPropertyChangeListener("foo", listener);
    registration.remove();
    // listener is not called. Otherwise its assertion fails.
    map.setProperty("foo", "bar", true);
}

Example 3 with PropertyChangeListener

use of com.vaadin.flow.dom.PropertyChangeListener in project flow by vaadin.

@Test
public void addSeveralPropertyChangeListeners_fireEvent_listenersAreNotified() {
    ElementPropertyMap map = createSimplePropertyMap();
    AtomicBoolean first = new AtomicBoolean();
    AtomicBoolean second = new AtomicBoolean();
    PropertyChangeListener listener1 = ev -> first.set(!first.get());
    PropertyChangeListener listener2 = ev -> second.set(!second.get());
    map.addPropertyChangeListener("foo", listener1);
    map.addPropertyChangeListener("foo", listener2);
    map.setProperty("foo", "bar", true);
    Assert.assertTrue(first.get());
    Assert.assertTrue(second.get());
