Java Swing JTable以编程方式选择多行 [英] Java Swing JTable select programmatically multiple rows

问题描述

我有一个包含多行的JTable，每行通过散点图上的Point表示.我要做的是，当在散点图中选择了给定点时，我必须将此选择与选择JTable中的相应行相关联.

I have a JTable with multiple rows and every row is presented via Point on a scatter plot. What I have to do is when a given point is selected on the scatter plot I have to associate this selection with selecting of the corresponding row in the JTable.

我有一个整数，代表我必须突出显示的行.

I have an Integer that represents, which row I have to highlight.

我尝试过的是:

    JTable table = new JTable();
...
...// a bit of code where I have populated the table
...
   table.setRowSelectionInterval(index1,index2);

因此，这里的问题是该方法选择了给定范围[index1，index2]中的所有行.我想选择例如1,15,28,188等行.

So the problem here is that this method selects all rows in the given range [index1,index2]. I want to select for example rows 1,15,28,188 etc.

你怎么做到的?

推荐答案

要仅选择一行，请将其作为开始索引和结束索引进行传递:

To select just one row, pass it as both the start and end index:

table.setRowSelectionInterval(18, 18);

或者，如果要选择多个不连续的索引:

Or, if you want to select multiple, non-contiguous indices:

ListSelectionModel model = table.getSelectionModel();
model.clearSelection();
model.addSelectionInterval(1, 1);
model.addSelectionInterval(18, 18);
model.addSelectionInterval(23, 23);

或者，您可能会发现实现自己的ListSelectionModel子类并使用它来跟踪表和散点图上的选择是一种更清洁的解决方案，而不是侦听散点图并强制表进行匹配.

Alternately, you may find that implementing your own subclass of ListSelectionModel and using it to track selection on both the table and the scatterplot is a cleaner solution, rather than listening on the scatterplot and forcing the table to match.
