Custom Button Dialog - Is there a better way?

Hi,

I was wanting to display a message box that give's the user 4 choices.  The standard DzMessageBox has methods that allow up to 3 buttons/choices for the user, so I thought I would design a custom dialog that allows a variable number of buttons to be displayed.  The snippet shows how I've gone about this, and in particular how I've connected each button's signal with a function that tells me which button has been pressed.  The code seems to work OK, but I'm no javascript guru.  I can't help wondering if there's a better way of coding this instead of using 'eval()':

var oDlg = new DzDialog();
oDlg.caption = "My Dialog Box";

var nBtnPressed;

var oVBoxLayout = new DzVBoxLayout(oDlg);
oVBoxLayout.autoAdd = true;
	
for (var i = 0; i < 4; i++) {
	var oBtn = new DzPushButton(oDlg);
	oBtn.autoDefault = false;
	oBtn.text = "Button: " + i;
	 
	var code
	 = "function fnc() {"
	 + "  nBtnPressed = " + i + ";"
	 + "  oDlg.close();"
	 + "}";
	eval(code);
	
	connect(oBtn, "clicked()", fnc );	
}
oDlg.exec();

print(nBtnPressed);
