Question

I want to list all controls (buttons, datagrids, etc) in a container

This works but gives me a warning 1008: variable 'comp' has no type declaration.

for (var i:int = 0;i<this.numElements;i++)
{
    var comp = this.getElementAt(i);
    trace(comp.id);
}

This is how I thought it should work but gives me a compiler error 1119: Access of possibly undefined property id through a reference with static type mx.core:IVisualElement.

for (var i:int = 0;i<this.numElements;i++)
{
    var comp:IVisualElement = this.getElementAt(i);
    trace(comp.id);
}

In my head, when I get a compiler warning it’s because I’m not doing something the way it is supposed to be.

Are there any alternatives to reference the id property? A method I’m missing even a whole different way iterate through all the controls?

Answer 1

Type it as a UIComponent. Components will extend this class. (fl.controls components and mx.core components both extend a UIComponent class)
