如何在Netbeans中更改Java应用程序的主题？

Question

I want to change the look of a Java application. I'm just using Netbeans and I don't like the look of metal in it, Instead I want to change it to the Windows look. Is there any way to do it?

I want to make it look like this.

But instead, when I run it, this is what the default look or theme of it is.

Is there any steps to change the default look of it?

Answer 1

Basically:

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

Will set the Look and feel to the one that your Operating System uses.

Take a look at this java tutorial which also lists the available themes and how to apply them.

Answer 2

Try this :

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