Examples with CellVisualChangeEvent org.eclipse.nebula.widgets.nattable.layer.event.CellVisualChangeEvent used on opensource projects

Example 1 with CellVisualChangeEvent

use of org.eclipse.nebula.widgets.nattable.layer.event.CellVisualChangeEvent in project nebula.widgets.nattable by eclipse.

the class DataLayerCommandHandlingTest method handleSameUpdateDataCommandRaisesNoEvents.

@Test
public void handleSameUpdateDataCommandRaisesNoEvents() throws Exception {
    LayerListenerFixture listener = new LayerListenerFixture();
    this.dataLayer.addLayerListener(listener);
    this.dataLayer.doCommand(this.command);
    Assert.assertTrue(listener.getReceivedEvents().size() == 1);
    Assert.assertTrue(listener.getReceivedEvents().get(0) instanceof CellVisualChangeEvent);
    // as calling the UpdateCommand with the same value should not trigger
    // any event
    // the size of the received events will stay 1 (the one event from
    // before which is cached)
    this.dataLayer.doCommand(this.command);
    Assert.assertTrue(listener.getReceivedEvents().size() == 1);
}

Example 2 with CellVisualChangeEvent

use of org.eclipse.nebula.widgets.nattable.layer.event.CellVisualChangeEvent in project nebula.widgets.nattable by eclipse.

the class SummaryRowIntegrationTest method shouldFireCellVisualChangeEventOnceSummaryIsCalculated.

@Test
public void shouldFireCellVisualChangeEventOnceSummaryIsCalculated() throws Exception {
    // need to resize because otherwise the ViewportLayer would not process
    // the CellVisualChangeEvent any further
    this.natTable.setSize(800, 400);
    LayerListenerFixture listener = new LayerListenerFixture();
    this.natTable.addLayerListener(listener);
    // Trigger summary calculation
    this.natTable.getDataValueByPosition(this.askPriceColumnIndex, 4);
    Thread.sleep(500);
    assertTrue(listener.containsInstanceOf(CellVisualChangeEvent.class));
    CellVisualChangeEvent event = (CellVisualChangeEvent) listener.getReceivedEvents().get(0);
    assertEquals(this.askPriceColumnIndex, event.getColumnPosition());
    assertEquals(4, event.getRowPosition());
    Collection<Rectangle> changedPositionRectangles = event.getChangedPositionRectangles();
    assertEquals(1, changedPositionRectangles.size());
