Question

i have this function in my project

public function changeFormItemsLabelWidth(form:Form, width:int):void
{
    var formItemsArray:Array = form.getChildren();
    for( var i:int = 0; i < formItemsArray.length; i++){
        if(formItemsArray[i].className == "FormItem"){
            var formItem:FormItem = formItemsArray[i] as FormItem;
            formItem.setStyle("labelWidth", width);
        }
    }

and i’m getting this error:

1061: Call to a possibly undefined method getChildren through a reference with static type spark.components:Form.

Can someone tell me how can i replace getchildren method? because i’m migration to flex 4 and this method no longer exists.

EDIT:

Tanks for the help i did something like this and it works

public function changeFormItemsLabelWidth(form:Form, width:int):void
{

    var it:int = 0;
    var n:int = form.numElements;
    for (it; it < n; it++)
    {
        var formItemsArray:Array = form.getElementAt(it) as Array;
    }

    for( var i:int = 0; i < formItemsArray.length; i++){
        if(formItemsArray[i].className == "FormItem"){
            var formItem:FormItem = formItemsArray[i] as FormItem;
            formItem.setStyle("labelWidth", width);
        }
    }
}

You’ll need to use form.numElements and iterate. Each element is reachable via form.getElementAt( iterator ).
