[MonkeyC] Can I cast a symbol to integer?

Former Member over 10 years ago

Can I cast or convert a symbol to integer? Or show me please the other way to build and manipulate menu from an array.

Sample code:

menu = new Ui.Menu();
for(var i=0;i<data.size();i++) {
menu.addItem(data, i);
}
Ui.pushView( menu, new MenuInput(), SLIDE_LEFT );

.... Ui.MenuInputDelegate {
function onMenuItem(item) {
System.println("Select: "+data[(CAST!!!)item]);[/FONT]

Oh dear. I didn't read that very well did I. I think I've got an example somewhere, I'll hunt around.

I seem to remember creating an array of symbols. Since a menu can only contain 16 items that's as big as it needs to be, or the max you expect. Something like...

var symbols = [
	:sym0,
	:sym1,
	:sym2,
	:sym3,
	:sym4
	// .....
	];
	
for(var i=0; i < data.size(); i++) {
	menu.addItem(data, symbols);
}

function onMenuItem(item) {
	for(var i = 0; i < symbols.size(); i++) {
		if(item == symbols) {
			System.println("Select: " data);
		}
	}
}
[/CODE]
