how do u create menus, i have seen books and stuff,
but they don't help. i need to know how to open from
a file with the open box popping up. like, how do u
save to a file, open from a file, etc. all the books
say is that u can create a menu and u need an
actionlistener. plz help, i hope i am not confusingThere are five basic steps you'll need to do.
Step 1. Create an AbstractAction
import java.awt.event.ActionEvent;
import javax.swing.AbstractAction;
import javax.swing.JFileChooser;
AbstractAction openAction = new AbstractAction("Open File...") {
public void actionPerformed(ActionEvent e) {
JFileChooser myChooser = new JFileChooser( );
// <YOUR_COMPONENT> is the containing Component, like the JDialog.
myChooser.showDialog(<YOUR_COMPONENT>, "Open File...");
Step 2. Create a JMenuItem and attach your newly created AbstractAction.
import javax.swing.JMenuItem;
JMenuItem myMenuItem = new JMenuItem(openAction);
Step 3. Add the JMenuItem you just created to your JMenu
import javax.swing.JMenu;
JMenu myFileMenu = new JMenu("File");
myFileMenu.add(myMenuItem);
Step 4. Add the JMenu you just created to a JMenuBar
import javax.swing.JMenuBar;
JMenuBar myMenuBar = new JMenuBar( );
myMenuBar.add(myFileMenu);
Step 5. Set the menu bar of your parent JDialog or JFrame to the JMenuBar you just created is Step 4.
import javax.swing.JDialog;
JDialog mainDialog = new JDialog( );
mainDialog.setJMenuBar(myMenuBar);
