java - 调用 JTable 的 listselectionlistener

Question

成功添加 ListSelectionListener 并让它注册用户操作后，我现在需要在从不同的类初始化包含它的 JFrame 期间在 JTable View 中预选一行:

// 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);

因此，只要您的其他类引用了该表，您就可以执行此操作。
