How to use a string-variable as QSObject in a script

Message 1 in thread

Hi out there
I would like to ask if there is a possibility in QSA 1.2.0 to use a string 
variable for calling static functions of a class with the name of that 
string:

function getRegisteredWrapper( className )
{
	var obj;
	var objArray = Application.getRegObjArray( className );

//////////////// I would like to make the next line work //////////
	if( "className".canConvert( objArray[0] )   
		obj = objArray[0];

	return obj;
}

All Wrapper-Objects in my app have the static function "canConvert".

Any ideas? 
If that is not possible yet, it´s a suggestion for QSA 2.0.

	Greetings
		Jens

Hi, Jens.

You're calling the method canConvert on a String-object here, which will 
not work. What you can do is

if (eval("className" + ".canConvert(objArray[0])"))

You will also have to register the class using an QSObjectFactory with a 
staticDescriptor to be able to call static functions on it.

best regards,
Eskil
