Thread: Help using Flowlayout

Hi,
Just signed up, have a problem, I am using a flow layout and a JMenu for a program I have created. But I cannot find out how to connect a new window to the JMenu, I have my program set so that it loads a Menu and at the top you have the selection to swap to a different Menu but I do not know how to do this.
Here is a snippet of my code
I just would like to know if anyone could help me connect the menu on the option to a new window.

Thanks

//Creates Menu
		JMenuBar menuBar = new JMenuBar();//Creates a new Menu
		JMenu menu = new JMenu("Open Applications");//Add Name of Menu
 
		//Adds a Menu Item to the toolbar
	    JMenuItem Doors = new JMenuItem("Operate Doors");
		JMenuItem Lights = new JMenuItem("Turn Lights On/Off");
 
		menu.add(Doors);
		menuBar.add(menu);
 
		menu.add(Doors);//Adds a new item Option to the menu
		menu.add(Lights);//Adds a open item Option to the menu
		menuBar.add(menu);//Adds a an Add Option to the menu
		setJMenuBar(menuBar);//Adds a menu to the window
 
		setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);//Closes whole program on exit
		setSize(750,350);//Sets the Size of the window
		setVisible(true);
