Examples
The following example uses the DigitExample class to create a new digit on the stage. The digit values are controlled by a combo box. 
     
    package {
        import com.williammalone.Digit;
        import fl.controls.ComboBox;
       
        public class DigitExample extends Digit {
            private var digit:Digit;
            private var digitHeight:Number = 100;
            private var digitColor:uint = 0x557755;
            
            public function DigitExample() {
                digit = new Digit();
                digit.color = digitColor;
                addChild(digit);
                createComboBox();
            }
      
            private function createComboBox():void {
                var changeDigit:ComboBox = new ComboBox();
                changeDigit.width = 120;
                changeDigit.x = 40;
                changeDigit.y = 10;
                changeDigit.prompt = "Select a digit";
                changeDigit.addItem( { label: "0", data:0 } );
                changeDigit.addItem( { label: "1", data:1 } );
                changeDigit.addItem( { label: "2", data:2 } );
                changeDigit.addItem( { label: "3", data:3 } );
                changeDigit.addItem( { label: "4", data:4 } );
                changeDigit.addItem( { label: "5", data:5 } );
                changeDigit.addItem( { label: "6", data:6 } );
                changeDigit.addItem( { label: "7", data:7 } );
                changeDigit.addItem( { label: "8", data:8 } );
                changeDigit.addItem( { label: "9", data:9 } );
                addChild(changeDigit);
                changeDigit.addEventListener(Event.CHANGE, onDigitChanged);
            }
          
            private function onDigitChanged(e:Event):void {
                digit.value = changeDigit.selectedItem.data;
            }
        }
    }
