如何刷新表中的单行? [英] How to refresh a single row in a table?
问题描述
是否可以刷新 vaadin table
组件的单行?
Is it possible to refresh a single row of a vaadin table
component?
到目前为止,如果表格行编辑完成,我只是刷新整个表格:
So far, if table row editing is finished, I'm just refreshing the whole table:
table.refreshRowCache();
但这可能会导致大表的性能问题.那么,如何刷新单行?
But that will probably cause performance issues later for large tables. So, how could a single row be refreshed?
推荐答案
我在 Vaadin 论坛上发现了这个似乎很有用:https://vaadin.com/forum/#!/thread/408555/408554

我还没有试过,但 Henri Sara(Vaadin 开发人员)建议了这个解决方案:
I haven't yet given it a go but, Henri Sara (Vaadin developer) suggested this solution:
Property statusProperty = pqTable.getContainerProperty(itemId, "statusString");
if (property instanceof MethodProperty) {
((MethodProperty) statusProperty).fireValueChange();
}
他还指出此方法可能会在未来版本中更改(并且可能已经这样做了:S)
He also notes that this method may change in a future version (and may have done so already :S)
