Accessing Children of VBox

Question

Hello All,
I have dynmaically created some CheckBox's and added them to a VBOX.
What i want to do is create a function that will iterate through them all and deselect. I have got this far:
private function clearSelection():void
            for (var i:int = 0; i < campaignRadioButtons.numChildren; i++) {
                var tmpCheckBox:CheckBox = new CheckBox
                tmpCheckBox = CheckBox(campaignRadioButtons.getChildAt(i));
                trace (tmpCheckBox.label);
Ok so this at the moment returns all of the labels. What I want to do is get access to the 'selection' attrubute and set it to false. How do I do this?.. without having to re add them all over again.
Thanks

Answer 1

private function clearSelection():void
    var n:int = campaignRadioButtons.numChildren;
    for (var i:int = 0; i < n; i++)
        var tempCheckBox:CheckBox = CheckBox(campaignRadioButtons.getChildAt(i));
        tempCheckBox.selected = false;
Note: DON'T do
private function clearSelection():void
    var n:int = campaignRadioButtons.numChildren;
    for (var i:int = 0; i < n; i++)
        var tempCheckBox:CheckBox = new CheckBox();
        tempCheckBox = CheckBox(campaignRadioButtons.getChildAt(i));
        tempCheckBox.selected = false;
This needlessly creates n new CheckBox instances and frees them when the reference to the ith new CheckBox in tempCheckBox is overwritten with the reference to the ith existing CheckBox.
