调用JTable的listselectionlistener

Question

在成功添加ListSelectionListener并使其注册用户操作之后，在从不同的类初始化包含它的JFrame期间，我现在需要在JTable视图中预先选择一行：

// in constructor
rowSM_treatments = table_histories.getSelectionModel();
rowSM_treatments.addListSelectionListener(new ListSelectionListener() {
 public void valueChanged(ListSelectionEvent e) {
      if (e.getValueIsAdjusting()) return;
               ListSelectionModel lsm = (ListSelectionModel)e.getSource();
               if (lsm.isSelectionEmpty()) {
                   System.out.println("No rows are selected.");
               } else {
                   selectedRow_treatments = lsm.getMinSelectionIndex();
                   System.out.println("selected Row> " + selectedRow_treatments);
                   //do more
               }}});
// later on is this method which I mean to call from outside this class
  public void setSelectedRow(int row){
   rowSM_treatments.setLeadSelectionIndex(row);       
     }

Answer 1

我通常只是访问表格，而不是直接使用选择模型：

table.changeSelection(row, 0, false, false);

所以，只要你的另一个类有一个对表的引用，你就可以这样做。
