将TextField添加到程序中

时间：2013-05-31 15:00:56

标签： java swing jpanel jtextfield layout-manager

我正在为我提供更好的应用程序版本。我仍然需要与给我的程序相同的组件，我只需要重新组织它。我还被告知不要复制任何原始代码并从头开始。第一个屏幕截图显示了我需要从原始程序添加到程序中的文本字段。第二个截图是我的程序。我不确定JTextField是否最适合这个。我的代码如下。我尝试使用JLabel添加一个JTextField并将其居中，但是当我运行该程序时，它会覆盖程序中的其他所有内容，并且只显示一个小白框。

转到JTextArea

JTextArea是一个显示纯文本的多行区域。
