调试我的按钮

Question

这是我的 JPanels class，用于我正在开发的一个小程序。该程序启动并正确显示我的 GUI。问题是出于某种原因我的 actionEvent 没有触发 onClick。

我在 actionPerformed 中输入了一个 println 以查看它是否真的启动了事件，但发现它没有。你们中的任何人都可以帮我弄清楚我哪里出了问题吗？

这是有问题的 class。

            model.addRow(row);

         }
    });



    userInput.add(Buttons.createLogButton());

    displayInput.setLayout(new BorderLayout());

    displayInput.setLayout(new BorderLayout());
    displayInput.add(table.getTableHeader(), BorderLayout.PAGE_START);
    displayInput.add(table, BorderLayout.CENTER);

    JScrollPane pane = new JScrollPane(table, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
            JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
    pane.setSize(825,700);

    displayInput.add(pane);


}

public JPanel getUserInput() {
    return this.userInput;
}

public JPanel getDisplayInput(){
    return this.displayInput;
}
}

提前致谢！如果您需要查看任何其他 classes 或需要更多信息，请告诉我！几天来我一直在努力解决这个问题，真的需要另一双眼睛来仔细检查。

您创建了两次日志按钮。尝试更改您的代码：

Button btnLog = Buttons.createLogButton();
btnLog.addActionListener(new ActionListener() {
  ...
}
userInput.add(btnLog);
