Answer 3

You're not being very clear with the question. If you want to add a ComboBox to the screen in AS3, your code works, except you need to attach it to something. eg,

var c:ComboBox = new ComboBox();
c.dataProvider = yourData;
someCanvas.addChild(c);

However, if you want to build your own ComboBox and have it pop up in a similar way, you're treading into more complicated land. The basics are that it's just a TextInput control where you use the PopupManager to show/hide a List object depending on the user action (eg, click, typing, etc...). But you will run into lots of focus/event issues.

Take a look at the ComboBox source code in the Flex SDK.
