Examples with Handler org.gwtproject.user.cellview.client.AbstractHasData.RedrawEvent.Handler used on opensource projects

Example 1 with Handler

use of org.gwtproject.user.cellview.client.AbstractHasData.RedrawEvent.Handler in project gwtproject by treblereel.

the class CellTableTest method testTableRenderedEvent.

public void testTableRenderedEvent() {
    final Counter counter = new Counter();
    CellTable<String> table = createAbstractHasData(new TextCell());
    table.addRedrawHandler(new Handler() {

        @Override
        public void onRedraw() {
            counter.increment();
        }
    });
    // Cause table to redraw by removing a column.
    Column<String, ?> column1 = table.getColumn(1);
    table.removeColumn(column1);
    table.getPresenter().flush();
    assertEquals(1, counter.getCount());
    // Cause the table to redraw by resetting the {@link CellTableBuilder}.
    table.setTableBuilder(new DefaultCellTableBuilder<>(table));
    table.getPresenter().flush();
    assertEquals(2, counter.getCount());
}

Example 2 with Handler

use of org.gwtproject.user.cellview.client.AbstractHasData.RedrawEvent.Handler in project gwtproject by treblereel.

the class AbstractHasDataTestBase method testRenderedEvent.

public void testRenderedEvent() {
    final Counter counter = new Counter();
    AbstractHasData<String> hasData = createAbstractHasData(new TextCell());
    hasData.addRedrawHandler(new Handler() {

        @Override
        public void onRedraw() {
            counter.increment();
        }
    });
    // Cause redraw by changing the data.
    hasData.setRowData(Arrays.asList(new String[] { "a", "b", "c" }));
    hasData.getPresenter().flush();
    assertEquals(1, counter.getCount());
    // Cause redraw directly.
    hasData.redraw();
    hasData.getPresenter().flush();
    assertEquals(2, counter.getCount());
    // Cause a specific row to redraw.
    hasData.redrawRow(0);
    hasData.getPresenter().flush();
    assertEquals(3, counter.getCount());
