在我的Main类的main方法中，我有以下代码：
LogRegGUI mainMenu = new LogRegGUI();
mainMenu.setVisible(true);
LogRegGUI构造函数：
public LogRegGUI() {
initComponents();
}
LogRegGUI是我的GUI类。当我右键单击该类并选择“运行”时，我的GUI完美显示。
当我运行整个程序并调用main时，GUI格式略有错误（颜色不匹配且按钮显示不正确）。
我究竟做错了什么？
额外信息：
Netbeans 7.3 Beta 2
Mac OS X Mountain Lion
Java Swing
LogRegGUI代码：
package com.john.spp.view;
import java.sql.ResultSet;
import java.sql.Statement;
public class LogRegGUI extends javax.swing.JFrame {
/**
* Creates new form LoginGUI
*/
public LogRegGUI() {

最佳答案
再次只是一个猜测，但是尝试显示LogRegGUI GUI的其他代码库是否也使用Nimbus外观？在该类中创建任何GUI组件之前，是否还设置了外观？那是我对您的问题的猜测。
