NetBeans Swing TextArea不是静态的，会引起麻烦 [英] NetBeans Swing TextArea is not static, causes trouble

问题描述

我已经创建了一个名为texttextArea的JFrame，名为'outputTextArea'，我想在textArea中打印数据库查询的结果.但是，变量outputTextarea不是静态的，因此我无法在main方法中调用setText()方法来在textArea中打印数据库结果集.

I have created a JFrame with a textArea called 'outputTextArea' and I want to print the results from a database query in the textArea. However, the variable outputTextarea is not static and therefore I can't call the method setText() in the main method to print the db resultset in the textArea.

我想知道如何使此变量(私有javax.swing.JTextArea outputTextArea;)成为静态变量，因为NetBeans不允许我编辑此变量，因为它是由NetBeans拖放textArea时生成的.

I would like to know how I can make this variable (private javax.swing.JTextArea outputTextArea;) static, because NetBeans won't let me edit this variable because it was generated by NetBeans when I dragged and dropped the textArea.

推荐答案

我遇到了同样的问题. 在Netbeans IDE 8.0.2中: 1)在设计标签中 2)点击文本区域 3)转到属性->代码 4)变量修饰符->添加静态变量.

I had the same problem. In Netbeans IDE 8.0.2: 1) In the design tab 2) Click on the textarea 3) go to properties -> code 4) Variable Modifiers -> add static.
