我有一个基于排序/过滤功能的nattable http://www.eclipse.org/nattable/documentation.php?page=sorting 和示例6031_GlazedListsFilterExample.java
最初我的表有零行。

情景3:
在NatTable的初始“视图”之后,是否有理由不对列标题操作进行“更新”?换句话说,在第一次查看NatTable之后,无论行是否发生变化,似乎都会将表的存在/不存在考虑在内。
相关代码部分如下所示:
private CompositeLayer createExampleLayer(Collection<T> values,
IColumnPropertyAccessor<T> columnPropertyAccessor,
IDataProvider columnHeaderDataProvider, IConfigRegistry
configRegistry, Matcher<T> matcher) {
BodyLayerStack<T> bodyLayerStack = new BodyLayerStack<>(
values, columnPropertyAccessor);
// build the column header layer
DataLayer columnHeaderDataLayer = new
DefaultColumnHeaderDataLayer(columnHeaderDataProvider);
ILayer columnHeaderLayer = new
ColumnHeaderLayer(columnHeaderDataLayer, bodyLayerStack,
bodyLayerStack.getSelectionLayer());
SortHeaderLayer<T> sortHeaderLayer = new SortHeaderLayer<>
(columnHeaderLayer, new GlazedListsSortModel<T>
(bodyLayerStack.getSortedList(), columnPropertyAccessor,
configRegistry,
bodyLayerStack.getBodyDataLayer()), false);
FilterRowHeaderComposite<T> filterRowHeaderLayer = new
FilterRowHeaderComposite<>(
new DefaultGlazedListsFilterStrategy<T>
(bodyLayerStack.getFilterList(), columnPropertyAccessor,
configRegistry),
sortHeaderLayer, columnHeaderDataLayer.getDataProvider(),
configRegistry);
// Omitted code for rowHeaderLayer and cornerLayer
return new GridLayer(bodyLayerStack, filterRowHeaderLayer,
rowHeaderLayer, cornerLayer);
}
public BodyLayerStack(Collection<T> values,
IColumnPropertyAccessor<T> columnPropertyAccessor) {
eventList = GlazedLists.eventList(values);
TransformedList<T, T> rowObjectsGlazedList =
GlazedLists.threadSafeList(eventList);
this.sortedList = new SortedList<>(rowObjectsGlazedList, null);
// wrap the SortedList with the FilterList
this.filterList = new FilterList<>(sortedList);
this.bodyDataProvider = new ListDataProvider<>(this.filterList,
columnPropertyAccessor);
this.bodyDataLayer = new DataLayer(getBodyDataProvider());
// layer for event handling of GlazedLists and PropertyChanges
GlazedListsEventLayer<T> glazedListsEventLayer = new
GlazedListsEventLayer<>(bodyDataLayer, this.filterList);
this.selectionLayer = new SelectionLayer(glazedListsEventLayer);
ViewportLayer viewportLayer = new ViewportLayer(getSelectionLayer());
setUnderlyingLayer(viewportLayer);
}
private void enableSorting() {
this.nattable.addConfiguration(new SingleClickSortConfiguration());
}
答案 0 :(得分:1)
看起来SortHeaderLayer
的创建不正确。 GlazedListsSortModel
的最后一个参数必须是列标题的IDataLayer
,而不是正文图层。
将代码更改为以下代码可以使事情有效。它至少在我身边。
SortHeaderLayer<T> sortHeaderLayer = new SortHeaderLayer<>
(columnHeaderLayer, new GlazedListsSortModel<T>
(bodyLayerStack.getSortedList(), columnPropertyAccessor,
configRegistry,
columnHeaderDataLayer), false);
