nimbusBase in Nimbus Look And Feel

Here is an example using UIManager.put("nimbusBase",Color c) for NimbusLookAndFeel illustrating eight components in swing. Here, i've used gray color, you can use any of the colors and choose from rgb or hex.

Structure of UIManager.put()

UIManager.put(Object propertyName, Object propertyValue);

UIManager is present in javax.swing package and Object is present in java.lang package.

What is nimbusBase?

nimbusBase is a property name that is given as the first parameter to the UIManager.put() method, this represents the base color of the components in the nimbus look and feel.

Ready for firing? OK. Let's go!

// Add menuitem to JMenu menu
menu.add(menuitem);

// Add submenuitem to submenu
submenu.add(submenuitem);

// Add submenu to menu
menu.add(submenu);

// Add menu to menubar

// Create JComboBox jc

// Add items to JComboBox jc
jc.addItem("Apples");

// Create a Vector that can hold String objects.

// Add items to the Vector v
v.add("C");

// Make the JList fat.

// Create a JScrollPane for JList jl

// Add JScrollPane js to JFrame

// Create JSpinner jp

// Make it fat.

// Add JSpinner jp to JFrame

// Create a JProgressBar jsp

// Set the value i to JProgressBar, the effect comes.

}
});

// Start the timer
