Have items in JMenubar at rightmost positionTag(s): Swing
javax.swing.Box.createGlue() will create a "greedy" component: when it is added to a container it takes all remaining horizontal and vertical space. Adding such a glue component to the menubar will cause remaining menus/components to 'flow' to the right.
import javax.swing.*; import java.awt.event.*; class RightJMenuBar { public static void main(String args[]) { new RightJMenuBar().doit(); } public void doit() { JFrame frame = new JFrame("Real's HowTo"); JMenuBar menuBar = new JMenuBar(); // Create a menu JMenu menu = new JMenu("Menu Label"); JMenuItem item = new JMenuItem("item"); menu.add(item); menuBar.add(menu); // shift to the right menuBar.add(Box.createGlue()); // this button will be shifted right on the menubar Action actionQuit = new AbstractAction("Quit") { public void actionPerformed(ActionEvent evt) { System.exit(0); } }; menuBar.add(new JButton(actionQuit)); frame.setJMenuBar(menuBar); frame.setSize(300,300); frame.setVisible(true); } }
