How to wait for user input?

I agree with omgallnamestaken.  It seems like a lot of extra work and the creation of functions that do nothing but handle user clicks. 

My code checks to see if the player has used up all of their movement points.  EndOfTurn is triggered by a button click.  It asks the question "are you sure you want to continue even though you have points left".  The code to get a confirmation has been "modularized" into function displayConfirm so I can reuse it.  I find it very frusturating that i have to turn these 3 lines of code into several unecessary functions with listeners.

This:

function EndOfTurn(e):void {

     if (points > 0) rc = displayConfirm("Are you sure you want to continue even though you have points left?")

     if (rc = no) return;

}

Becomes This:

function displayConfirm(e):void {

//draw the message box which would normally be part of displayConfirm (seveal dozen lines of code)

messagebox.addchild(question);

messagebox.addchild(yesbtn);

messagebox.addchild(nobtn);

addChild(mesagebox);

yesbtn.addEventListener(MouseEvent.CLICK,callEndOfTurn);

nobtn.addEventListener(MouseEvent.CLICK.closeConfirmationCheck);

function closeConfirmationCheck(e):void {

removeChild(messagebox);

}

function callEndOfTurn(e):void {

removeChild(messagebox);

EndOfTurn();

}

Fine, but now displayConfirm has become specific to the EndOfTurn function. I thought about passing parameters to displayConfirm but realized that I can't because it has to accept an event from the listener and that's all it can accept.  I could have it switch based on the button's name and then dynamiclly display the right message and then call the function that it's supposed to.  But I feel this is much more compliated than the original function in which you just feed it a message and it returns a yes or no.

There are way too many things that need to wait and I can't build those into the event handler. I just want an easy way to get user confirmation in a large application. If I just use event listener, then when the user clicks yes, I will have to somehow tell the application what it was waiting for since the program doesn't pause for event listener (I can pass large amount of data between the events but I just feel sick about that). It would be ok if there is a event listener, once added, will pause the program until that event happens. (even that, I'm still a bit confused about how to structure the return value and event handler).

Any simple solution out there?
