for each (child:someClass) in MovieClip? doesn't work!

hello,

In short:
How can I remove all children that are instances of a given class?

I've tried the following:

Code:

---

for each (var obj:InfoBox in infoPanel)
{
    infoPanel.removeChild(obj);
}

---

if i do that i get this error:

Code:

---

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@4304f821 to InfoBox

---

however, if i use MovieClip instead of InfoBox (for each (var obj:MovieClip in infoPanel), it works well and it removes all movieclips.

and if i trace infoPanel.getChildAt(i) (in a loop), i get all the objects [object InfoBox] as well as the objects MovieClips.

Why?

thanks in advance!

so, i also tried:

Code:

---

                for each (var obj:* in infoPanel)
                {
                        trace(" clean this!!! " + obj + ", name: " + obj.name);
                               
                        if (obj is InfoBox)
                                info.removeChild(obj)
                               
                }

---

it only traces the movieclips!! why doesn't it trace the objects InfoBox then?

:confused:

for each.. in only iterates over the dynamic properties of an object. You are trying to iterate over the display children. You need to use a for loop with getChildAt and numchildren.

Code:

---

for (var i:int = 0; i < infoPanel.numChildren; i++){
  var dc:DisplayObject = infoPanel.getChildAt(i);
  if (dc is InfoBox){
    infoPanel.removeChild(dc);
    i--; //removed that child, so revisit that index.
  }
}

man , i really appreciate your help. exactly what i needed to know.

THANKS!
