beside each other. When you click the combo box, you’ll see a list of items. When you click
the button, it clears the combo box’s items:
my_cb.move(10, 10);
clear_button.move(120, 10);
// Create dataprovider.
var myDP_array:Array = new Array();
myDP_array.push({data:1, label:"First Item"});
myDP_array.push({data:2, label:"Second Item"});
my_cb.dataProvider = myDP_array;
// Define event listener object.
var clearListener:Object = new Object();
clearListener.click = function(evt_obj:Object){
my_cb.removeAll();
}
// Add Listener.
clear_button.addEventListener("click", clearListener);
