Re: [flexcoders] Re: Package with internal class problem

Actually that DID give me an error :) But it's not far from what I wanted. I resolved it with the following:
public static var cross:Class = Cross;
I only needed the reference to the internal class so I could call its static variables. But that gave me a null.

If I created a constructor in CursorDepot and called:
trace(cross ); // output: Class [Cross]
it worked fine, it gave me the expected results.

But when called from outside the class:
trace(CursorDepot.cross ); // output: null

I guess it's just not possible to call anything from internal classes, not even when going via the public class. Or am I mistaken? I'd like to be :)

Should this:


// -- CursorDepot.as :
package cursors {
    
    public class CursorDepot {
        
        public static var cross:Cross = Cross;
        
    }    
}

 

Be:


// -- CursorDepot.as :
package cursors {
    
    public class CursorDepot {
        
        public static var cross:Cross = new Cross();
        
    }    
}

I'd be a little surprised if the original compiles, which is why I think it might just be a typo in your email.

I guess I'm not permitted to delegate an internal class' public static variable through the public class' public static variable. Too bad, I had to create a lot of small classes for each cursor for the application to work. Still, I'm wondering if there's a way to package those classes to keep the amount of files to a minimum.

Anyone with a bright idea?

Hi list,

I'm trying to combine multiple small classes into one package, but to no avail..
Could someone help me with this?

The error I get is:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

// -- CursorDepot.as :
package cursors {
    
    public class CursorDepot {
        
        public static var cross:Cross = Cross;
        
    }    
}

internal class Cross {
    [Embed(source="../cursors/cross.png")]
    public static var icon:Class;
    
    public static var offsetX:int = 0;
    public static var offsetY:int = 0;
}

// -- in the application:
public function init():void {
    setCursor(CursorDepot.cross);
}

public function setCursor(cursorClass:*):void {
    trace(cursorClass) // outputs: null !!! why?
    var cursorID:int = setCursor(cursorClass.icon, cursorClass.offsetX, cursorClass.offsetY);
}


Thank you in advance,

Bart Wttewaall
