Take a look at ApplicationDomain Class it provides some methods that will help
you do this. Here is an example of what you are trying to do I think...
try
{
var myClass:Class =
ApplicationDomain.currentDomain.getDefinition(e.panelClassName) as Class;
var myInstance:* = new myClass();
}
catch(error:Error)
{
Alert.show("Error " + error);
return;
}
First we try to get a class definition from the panelClassName string. I say
try because on thing to keep in mind is that if the Class is not being used
else where in your app it may not be compiled into your swf. In this case the
getDefinition method will throw an error.
If we did get a Class back we then use it to make a real instance of that class.
