Callbacks

Oops....
I made this test because I didn't get it to work. Have been staring at it for an hour :S

Thanks.

But then I'm still stuck with this:

function pushMenu()
{
var menu = new MainMenu();
Ui.pushView(menu, new MainMenuInputDelegate(), Ui.SLIDE_RIGHT);
}


class MainMenu extends Ui.Menu
{
function initialize()
{
setTitle("My menu");

addItem("Start", method(:onStart));
}

function onStart()
{
Systen.println("onStart");
}
}

class MainMenuInputDelegate extends Ui.MenuInputDelegate
{
function onMenuItem(item)
{
System.println("onMenuItem");
System.println(item instanceof Method);
item.invoke();
}
}


Shouldn't this work? I don't want a long if/else construct in my onMenuItem, so I thought I'd just pass a method as item id.

N.B I know for most cases I should use a resource for a menu, but the items won't always be the same.

Pfff. Solved it. Thanks.

class MainMenu extends Ui.Menu
{
function initialize()
{
setTitle("My menu");

addItem("Start", :onStart);
}
}

class MainMenuInputDelegate extends Ui.MenuInputDelegate
{
function onMenuItem(item)
{
var a = method(item);
System.println("onMenuItem");
System.println(a instanceof Method);
a.invoke();
}

function onStart()
{
System.println("onStart2");
}
}

Yeah. I discovered that one a while ago. Symbols are fun.
