problem in itemClick

Question

if (theData.hasOwnProperty("@id1")) {
    var myObj:Hello = new Hello();
    textArea.visible = false;               
    panel.addChild(myObj);
} else if (theData.hasOwnProperty("@id2")) {
    textArea.visible = false;
    var vijay:MCQ = new MCQ();
    panel.addChild(vijay);
}

When i click on the next item, the previous window is still visible. How can i destroy myObj. I am not able to do it through removeChild.

Answer 1

If panel only ever contains one object, you could use the following before adding the new one:

panel.removeAllChildren();

If there are a known number of "static" children in panel, you could conditionally remove the additional ones:

while (panel.numChildren > EXPECTED) {
    panel.removeChildAt(panel.numChildren - 1);
}

The best option would be to hold a reference to the object you added so that you can remove it explicitly using removeChild(). If these alternatives won't work, perhaps you could explain your constraints.
