例如：

public function createComboBox_clickHandler(event:Event):void { 
      var myComboBox:ComboBox = new ComboBox(); 
      var comboBoxDataProvider:ArrayCollection =new ArrayCollection([ 
       { name: "box1", value: "value1"}, 
       { name: "box2", value: "value2"}, 
       { name: "box3", value: "value3"}, 
       { name: "box4", value: "value4"} 
      ]); 

      myComboBox.x = 100; 
      myComboBox.y = 100; 
      myComboBox.dataProvider = comboBoxDataProvider; 
      myComboBox.labelField = "name"; 
      myComboBox.addEventListener(ListEvent.CHANGE, myComboBox_ClickHandler); 
      container.addElement(myComboBox); 
     } 

     public function myComboBox_ClickHandler(event:ListEvent):void{ 
      trace(event.currentTarget.selectedItem.value); 
     } 

和按键的点击（和他们两个容器）

<s:BorderContainer id="container" width="100%" height="100%"> 
    <s:Button id="createComboBoxButton" click="createComboBox_clickHandler(event)" label="Create a combobox dynamically"/> 
</s:BorderContainer>
