Thank you to everyone for your help...
I am getting closer. Here is my latest code. Seems I can't get the
room attribute to trigger an event. Any ideas?
/////////////////////////////////////////////////////////////////////
/////////////////////
// First, create an array of labels for the buttons
var labels_ar:Array = ["Option 1","Option 2","Option 3","Option 4"];
// Second, build 4 buttons and position them
public function addButtons(labels:Array, container:MovieClip,
startX:Number, startY:Number):Void
{
var button_offset:Number = 30;
var button_depth:Number = 10;
var i:Number = 0;
for (i = 0; i<labels.length;i++)
{
var current_button:MovieClip = container.createClassObject
(mx.controls.Button, "option" + i, button_depth,{label:labels[i]});
current_button.move(startX,startY+(button_offset*(i+1)));
current_button.setSize(200, 20);
current_button.addEventListener("click", clickHandler);
button_depth++;
}
}
// Third, listen for button clicks and when a button is clicked do
the following:
// 1) Trace out which button was clicked
// 2) Set the room attribute "selectedButton" equal to the
value of the button clicked
// 3) Highlight the selected button component
public function clickHandler(e:Object):Void
{
trace(this + " was just pressed.");
e.getRoomID().setAttributeOnServer("selectedButton", this,
true) // I can't figure out how to get the right room name
changeColor(this);
//setClientAttribute("whichButton", this, null, true, false, false);
}
// Fourth, when the room attribute is changed (selectedButton
changes) do something...
public function onUpdateRoomAttribute (e:URoomEvent):Void
{
trace("=============== selectedButton changed ===============");
}
// Change the color of the all of the buttons to "false", and set
the selectedButton color to "emphasized"
public function changeColor(buttonToColor):Void
{
trace("changeColor(" + buttonToColor + ") was called.");
_level0.option0.setStyle("emphasized", false);
_level0.option1.setStyle("emphasized", false);
_level0.option2.setStyle("emphasized", false);
_level0.option3.setStyle("emphasized", false);
buttonToColor.setStyle("emphasized", true);
}

Thanks!!! really appreciate it!
