how to make quit button in flash mx

[zextapo]

I know this should be simple one, but I can't find method to join the button with quit function. I am trying to make presentation which must have quit button.

Thanks in advance, and sorry for stupid question.

next time try to be more vague :)
do you mean like the "X" on the top right screen? or like enable=false;? or myButton_btn.onPress =quitFunction;

I meant myButton_btn.onPress =quitFunction;
How can I do that?

[coolioman]

on(press){
fscommand("quit");
}

like that?
