Problem : Change Nimbus Look and feel to Windows

Hello,
firstly sorry beacause i can't speak english a lot.
my problem is : my default look and feel now is NIMBUS , i want change it to Windows , so i add in main :
Java Code:

Code:

---

try {
                    UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
                } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                }

---

but when i do the exécution , i see the nimbus look not windows look.
Help me please.
Thanks.

Try the getSystemLookAndFeelClassName() method on UIManager.
Other than that, print the stack trace in the catch block in case youare getting an exception.

thanks for your answer , but i did't understand how i can't use getSystemLookAndFeelClassName()

Code:

---

UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
UIManager.getSystemLookAndFeelClassName();

---

this is the right syntaxe??
want mean print tack in the catch ?
sorry because i'm begginer in Netbeans
THANKS

No, instead of the String you are passing in, use the result of getSystemLookAndFeelClassName().
It returns the system L&F (this is under the assumption that you are on a Windows system) classname as a String.

i write this code :

Code:

---

public void run() {
new New_User().setVisible(true);
 String a =  UIManager.getSystemLookAndFeelClassName();
 System.out.println(a);}

---

the result is : com.sun.java.swing.plaf.windows.WindowsLookAndFeel .
but when i execute i see the nimbus designer :(think):

Have you changed the catch block to print the stack trace, in case there is an exception?

Code:

---

catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
  ex.printStackTrace();

---

}
like this ?

Yes.
Otherwise you won't know if something has gone wrong.

same problem existe , when i execute i see the nimbus designer.

Code:

---

public static void main(String args[]) {
        try {
            for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
                if ("Nimbus".equals(info.getName())) {
                    javax.swing.UIManager.setLookAndFeel(info.getClassName());
                    break;
                }
            }
        } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | javax.swing.UnsupportedLookAndFeelException ex) {
            java.util.logging.Logger.getLogger(New_User.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
        //</editor-fold>

        /* Create and display the form */
        java.awt.EventQueue.invokeLater(new Runnable() {
            @SuppressWarnings("CallToThreadDumpStack")
            public void run() {
                try {
                    new New_User().setVisible(true);
  String a =  UIManager.getSystemLookAndFeelClassName();             
 } catch ( Exception ex) {
 
  ex.printStackTrace();
            }
            } });}

There's nowhere in that code that you actually set the L&F to windows.
The only call up there to setLookAndFeel is only called on an L&F of "Nimbus".

Now it's ok , thanks for your help Tolls

Code:

---

public static void main(String args[]) {
        try {
            for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
                if ("Windows".equals(info.getName())) {
                    javax.swing.UIManager.setLookAndFeel(info.getClassName());
                    break;
                }
            }
        } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | javax.swing.UnsupportedLookAndFeelException ex) {
            java.util.logging.Logger.getLogger(New_User.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
        //</editor-fold>

        /* Create and display the form */
        java.awt.EventQueue.invokeLater(new Runnable() {
            @SuppressWarnings("CallToThreadDumpStack")
            public void run() {
                    new New_User().setVisible(true);
            } });}
