java - Jbutton 执行更多操作

Question

我有一个 JDialog，其中显示 Jtable，JTable 的单元格是一个打开新 JFrame (CoveNew) 的 JButton:

public void birthstats(String stat) {
    //System.out.println(classeMain);
    String titolo=new String();
    if ("nascite".equals(stat)){
        titolo=lingua_corrente.getString("nascite_title");
        elencojLabel.setText(titolo);
    }
    else{
        titolo=lingua_corrente.getString("anella");
        elencojLabel.setText(titolo);
    }
    Dimension dimensioni = new Dimension(500, 700);
    nascitejDialog.setSize(dimensioni);
    nascitejDialog.setTitle("GesAll 1.0 - " + titolo);
    nascitejDialog.setModal(true);

JTable 正确显示，我遇到的问题是，当我第一次单击 Jbutton 时，新的 JFrame 将显示一次，如果我再次单击，它将显示 7 的 3 倍，依此类推。你能帮我只展示一次吗？谢谢吉安卢卡。

Answer 1

您不应该将 JButton 添加到 TableModel。 JTable 使用呈现器和编辑器来显示数据。

参见Table Button Column一种允许您在列中存储文本但随后对该列使用自定义渲染器/编辑器的方法，使其看起来和操作就像一个按钮。您所需要做的就是在单击单元格时提供一个操作。
