You're gonna want to add MenuListeners to each of the menus above. Once you do, find out which of the JMenuItems is selected (getSelectedObjects)

 

by: VolatileVoidPosted on 2005-04-12 at 08:09:59ID: 13763116

Example--

I dunno if all my parentheses match or not, but I believe this will work:
    fileMenu.addMenuListener (
      new MenuListener () {
        public void menuSelected (MenuEvent e) {
          if (((JMenuItem)((JMenu)e.getSource ()).getSelectedObjects ()) == mnuDates) {
            /// do stuff here
          }
        }
       
        // other MenuListener functions here
      }
    );

 

by: DanFlyBoyPosted on 2005-04-12 at 08:44:00ID: 13763585

When i click the open button on the menu bar, I want a new window to apper, I am still unable to do this even though I added the MenuListerner.

 

by: VolatileVoidPosted on 2005-04-12 at 10:09:55ID: 13764663

Inside the MenuListener, you need to create a JFrame and show it.

I still have not gotten the menulisterner to work.  Any ideas?

 

by: ashok3sepPosted on 2005-04-12 at 10:53:02ID: 13765189

class myFrame extends Frame implements ActionListener
{

     public myFrame()
    {
              MenuItem newWindowItem;
              MenuBar myMenuBar = new MenuBar();    // create the menu bar
              Menu windowMenu = new Menu("window"); // create the menu
              newWindowItem = new MenuItem("add new window");   // create the menu item
              newWindowItem.addActionListener(this);  // add the listener for new window
     
               // add it to the Menu
              windowMenu.add(newWindowItem);
              myMenuBar.add(windowMenu);
              setMenuBar(myMenuBar);
     }
     public void ActionPerformed(ActionEvent e)
     {
            if(e.getSource() == newWindowItem)
            {       // if new window menu item is selected
                    Frame f = new myFrame();
                    f.setSize(100,100);
                    f.setVisible(true);                  
                    // create the new window
            }
      }
}

I tried the class Frame code, I could not get it to run, also, how would I implement this in my code that I published?
