我在我的应用程序上安装并正确应用了 JTattoo L&F，但由于某种原因，主 JFrame 没有得到 L&F！我认为这与它在 main 方法中使用 .setVisible(true); 实例化有关。方法，在为整个应用实例化 JTattoo L&F 之后！我尝试了一切，包括更改 JFrame 代码本身中的 L&F，无论我做什么，都没有任何效果......它就是不会让步！在谷歌上寻找类似的问题，没有发现任何相关的东西，我已经在这个问题上花了几个小时但无法弄清楚，我尝试了一切！包括“逆向工程”一些方法，都行不通！
这是我的代码：
public class DsrApplication {
public static MeniuPrincipalTaburi meniuTaburi = new MeniuPrincipalTaburi();
public static boolean isAdmin;
public static ArrayList<String> arrUti;
public static void main(String[] args) throws SQLException {
try {
//here you can put the selected theme class name in JTattoo
UIManager.setLookAndFeel("com.jtattoo.plaf.mint.MintLookAndFeel");
} catch (ClassNotFoundException ex) {
java.util.logging.Logger.getLogger(DsrApplication.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (InstantiationException ex) {
java.util.logging.Logger.getLogger(DsrApplication.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
java.util.logging.Logger.getLogger(DsrApplication.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (javax.swing.UnsupportedLookAndFeelException ex) {
java.util.logging.Logger.getLogger(DsrApplication.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
}
String connectionUrl = String.format("jdbc:mysql://%s:%s/%s", "127.0.0.1", "3306", "dsr");
DataBaseConnection db = new DataBaseConnection(connectionUrl, "root", "@Root123#");
Connection conn = db.getConnection();
Logare logare = new Logare();
meniuTaburi.setVisible(true);
MeniuPrincipalTaburi.Meniu.addTabNoExit("Logare", logare.getContentPane());
MeniuPrincipalTaburi.Meniu.setSelectedComponent(logare.getContentPane());
Map<String, String> utilizatori = new HashMap<>();
UtilizatoriDAO userManagement = new UtilizatoriDAO(conn);
try {
utilizatori = userManagement.getAll();
} catch (SQLException ex) {
Logger.getLogger(CreeareUtilizatori.class.getName()).log(Level.SEVERE, null, ex);
}
Map<String, String> getUtilizatori = new HashMap<>();
System.out.println(getUtilizatori.get("Admin"));
FisierDAO fisierDB = new FisierDAO(db.getConnection());
List<Fisier> fisiere = new ArrayList<>();
fisiere = fisierDB.getAll();
arrUti = userManagement.getNames();
}
这是 JFrame 的代码：
public class MeniuPrincipalTaburi extends javax.swing.JFrame {
/**
* Creates new form MeniuPrincipalTaburi
*/
public static JTabbedPaneCloseButton Meniu = new JTabbedPaneCloseButton();
public MeniuPrincipalTaburi() {
Meniu.setEnabled(true);
Meniu.setSize(1000, 500);
this.setSize(1000, 500);
this.add(Meniu);
initComponents();
ImageIcon img = new ImageIcon("C:\\Users\\Dragos\\Documents\\NetBeansProjects\\project\\Fisiere\\Alte Documente\\Logo\\transformator.png");
this.setIconImage(img.getImage());
}

如您所见，还尝试在 JFrame 的 L&F 代码中更改 Nimbus L&F……仍然没有！如果有人愿意提供任何提示，谢谢大家。
