To determine which version of Flash Player you are currently using--the standard version or the debugger version--you can use the Capabilities class. This class contains information about Flash Player and the system that it is currently operating on. To determine if you are using the debugger version of Flash Player, you can use the isDebugger property of that class. This property returns a Boolean value: the value is true if the current player is the debugger version of Flash Player and false if it is not.

The following example uses the playerType, version, and isDebugger properties of the Capabilities class to display information about the Player:

<?xml version="1.0"?>
<!-- logging/CheckDebugger.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:Script><![CDATA[
        import flash.system.Capabilities;

        private function reportVersion():String {
            if (Capabilities.isDebugger) {
                return "Debugger version of Flash Player";
            } else {
                return "Flash Player";
            }
        }
        private function reportType():String {
            return Capabilities.playerType + " (" + Capabilities.version + ")";
        }
    ]]></mx:Script>
    <mx:Label text="{reportVersion()}"/>
    <mx:Label text="{reportType()}"/>
</mx:Application>
The executing SWF file for the previous example is shown below:

Other properties of the Capabilities class include hasPrinting, os, and language.
