    Creating Menus

    hi,

    having problems creating menus in j2me.
    Found alot of code around using MenuElements, lists and all sorts of things.

    my code for the list is roughly like this:

    {
    List menu=new List("MainMenu",List.IMPLICIT);

    int num1, num2, num3,num4,num5;
    private Command cmd = new Command("Select", Command.OK, 1);
    Displayable display1;


    public void options()
    {
    num1 = 0;
    num2 = 1;
    num3 = 2;
    num4 = 3;
    num5 = 4;

    menu.append("Start Game", null);
    menu.append("High Scores", null);
    menu.append("Instructions", null);
    menu.append("About", null);
    menu.append("Exit", null);

    menu.addCommand(cmd);
    menu.setCommandListener(this);
    display1.setCommandListener(this);
    }

    The problem now is how to i check which one is pressed?

    Or is there a better way to do this?

    Is will be quick a simple menu as you can see.

    Any advice is appreciated

    From the getselectedIndex() how do i reference the specific menu option.

    How will the if statement go

    if(menu.getSelecetedIndex() == ?)
    {

    }

    Hi...


    int selectedOption = optionsMenu.getSelectedIndex();

    if(selectedOption == 0)
    {
    //code for the corresponding selection
    }

    else if(selectedOption == 1)
    {
    //code for the corresponding selection
    }

    else if(selectedOption == 2)
    {
    //code for the corresponding selection
    }

    Hope this helps...

    regards
    Gopal
