在RowSort操作之后执行操作 [英] Performing an action after a RowSort operation

问题描述

我有一个JTable和TableRowSorter，我想在完成排序后在 上执行操作.我一直在浏览网络，到目前为止，我还没有碰到太多运气.

I have a JTable and a TableRowSorter which I'd like to perform an operation after a sort is finished. I've been browsing the net, and so far I haven't had much luck.

最初，我以为只有RowSorterListener可以解决问题，但不幸的是，排序完成后它没有执行操作.

Initially I thought just a RowSorterListener would do the trick, but unfortunately it doesn't perform the operation after the sort is finished.

在JTable标头中添加MouseListener可能有效，但是解决方案并不十分优雅.

Adding a MouseListener to the JTable header could work, but the solution isn't terribly elegant.

有人有什么想法吗?

感谢一堆！

编辑(来自注释):在自定义TableModel类中扩展了AbstractTableModel的方法中添加了以下内容.在自定义TableModel类中设置/指定JTable时，将调用此方法.

Edit (from comment): The following is added in a method inside a custom TableModel class which extends AbstractTableModel. This method is invoked whenever the JTable is set/specified in the custom TableModel class.

sorter.addRowSorterListener(new RowSorterListener() {
    @Override public void sorterChanged(RowSorterEvent rowsorterevent) {
        rebuildMItems(); // The method which executes
    }
});

推荐答案

两种可能性:

1. 我看到您有一个自定义的RowSorter.您不能简单地在sort()方法的末尾添加对您的操作的调用吗?

1. I see you have a custom RowSorter. Couldn't you simply add a call to your operation at the end of the sort() method?

换句话说，您可以添加此内容吗?

In other words, can you add this:

@Override
public void sort() {
    super.sort();
    doSomethingAfterSortingIsDone();
}

到您的分拣机?

您当前的方法(在RowSorterListener中执行)执行两次操作:一次用于SORT_ORDER_CHANGED，一次用于SORTED.您可以检查事件的类型仅在正确的时间执行操作?

Your current method (doing it in a RowSorterListener) performs the operation twice: once for SORT_ORDER_CHANGED and once for SORTED. Can you check the event's type and only perform the operation at the correct time?
