How can the component be modified to forcefully always shown the colors list withou开发者_如何学运维t any interaction from the user?

You can call the open method (which calls an mx_internal method displayDropdown):

<?xml version="1.0" encoding="utf-8"?>
<mx:Application
 xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">

 <mx:Script>
  import mx.events.DropdownEvent;

  protected function initializeInterruption():void
  {
   color.addEventListener(DropdownEvent.CLOSE, interrupt);
  }

  protected function interrupt(event:Event):void
  {
   color.open();
  }
    </mx:Script>

 <mx:ColorPicker id="color" closeDuration="0" openDuration="0"
  initialize="initializeInterruption()"
  creationComplete="color.open()"/>

</mx:Application> 

You also have the option of extending the ColorPicker class and overriding some/all of these methods:

• keyDownHandler
• downArrowButton_buttonDownHandler
• open
• close

Let me know if that works, Lance
