我有一个显示Jtable的JDialog，JTable的一个单元是一个打开一个新JFrame的JButton（CoveNew）：

String titolo=new String();
if ("nascite".equals(stat)){

elencojLabel.setText(titolo);
}
else{
titolo=lingua_corrente.getString("anella");
elencojLabel.setText(titolo);
}

nascitejDialog.setSize(dimensioni);
nascitejDialog.setTitle("GesAll 1.0 - " + titolo);

JTable正确显示我遇到的问题是当我第一次点击Jbutton时，新的JFrame会显示一次，如果我再次点击它会显示3次7，依此类推。你能帮助我只展示一次吗？ 谢谢Gianluca。
答案 0 :(得分：2)
您不应该将JButton添加到TableModel。 JTable使用渲染器和编辑器来显示数据。
请参阅Table Button Column以获取一种方法，该方法允许您在列中存储文本，然后使用该列的自定义渲染器/编辑器，使其外观和行为类似于按钮。您需要做的就是在单击单元格时提供操作。
