在不单击列标题的情况下对JTable的条目进行排序 [英] sort JTable's entries without clicking on column header

问题描述

我已经使用DefaultRowSorter和自定义定义的行排序器类在JTable上实现了行排序.单击列标题以对表进行排序，一切正常.

I've implemented row sorting on a JTable both using DefaultRowSorter and my custom defined row sorter class. All works fine clicking on the column header to sort the table.

但是，如果我想从应用程序代码内部调用排序操作(不单击列标题)怎么办?我必须调用哪种方法?

But what about if I want to invoke a sort operation from inside my application code ( without clicking on the column header). Which method do I have to call ?

我通过以下方式初始化表格的行排序器:

I initialize my tables row sorter this way:

public void buildRowSorter() {
        TableRowSorter<MyModel> sorter = new TableRowSorter<MyModel>((MyModel)this.table.getModel());

        try {
            sorter.setComparator(0, new MyCustomComparator<Double>(sorter,0));
            sorter.setComparator(1, new MyCustomComparator<String>(sorter,1));
        } catch (ParseException e) {
            e.printStackTrace();
        }

        this.table.setRowSorter(sorter);
    }

现在，我想引用JTable(表)，以将关联的行排序器检索到模型的特定列，并在其上调用排序操作.

Now I would like, having a reference to the JTable (table), to retrieve the associated row sorter to a particular column of my model, and invoke a sort operation on it.

推荐答案

您有一个自定义的比较器(为什么保留对分类器的引用?看起来很腥)自定义RowSorter.

as far as I can see you have a custom comparator (why does that keep a reference to the sorter? looks fishy) not a custom RowSorter.

更改排序的预期方法是在RowSorter上调用toggleSortOrder(column).要获得更细粒度的控制，您可能需要访问DefaultRowSorter，f.i.其setSortKeys方法.

The intended way to change sorting is to invoke toggleSortOrder(column) on RowSorter. For more fine-grained control you can need access to the DefaultRowSorter, f.i. its setSortKeys method.
