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

Example 1 with PropertyChangeEvent

use of com.vaadin.flow.dom.PropertyChangeEvent 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 PropertyChangeEvent

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

the class ElementPropertyMap method putWithDeferredChangeEvent.

private PutResult putWithDeferredChangeEvent(String key, Serializable value, boolean emitChange) {
    Serializable oldValue = super.put(key, value, emitChange);
    boolean valueChanged = !Objects.equals(oldValue, value);
    if (valueChanged) {
        setFilterIfMapNode(oldValue, () -> null);
        setFilterIfMapNode(value, () -> createChildFilter(key));
    }
    PropertyChangeEvent event;
    if (hasElement() && valueChanged) {
        event = new PropertyChangeEvent(Element.get(getNode()), key, oldValue, !emitChange);
    } else {
        event = null;
    }
    return new PutResult(oldValue, event);
}
