I don't think there's a good answer to this question. There's no way to figure out via AS whether a component MIGHT dispatch a given event.
I did a search on livedocs to try to find all classes that dispatch a change event. This only seems to include base classes, so subclasses of any of these controls won't show up, so you'd hve to figure those out. Also note that this doesn't mean that some classes might dispatch other events that signify change that aren't specifically the same "change" event. And these change events don't necessarily mean "user input" either. All it means is that the component dispatches an event called "change". Here's the livedocs search: http://livedocs.macromedia.com/cfusion/search/index.cfm?loc=en_us&term=site%3Alivedocs.macromedia.com%2Fflex%2F201++%22change%3DNo+default%22&action=Search And here are the classes that come up: mx.controls.RadioButtonGroup mx.controls.sliderClasses.Slider (which means HSlider and VSlider as well) mx.controls.ColorPicker mx.containers.Accordion mx.containers.ViewStack mx.controls.DateChooser mx.controls.NumericStepper mx.controls.Button mx.controls.DateField mx.controls.PopUpMenuButton mx.controls.ComboBox mx.controls.TextInput mx.controls.TextArea mx.controls.Tree mx.controls.listClasses.ListBase (so that would mean all list controls like List, TileList, DataGrid, etc) So your best bet is probably to put together a more complete list of each component you want to define as having "user input" and then just check against that list using the "is" test as already mentioned. But I think the basic answer to your question is no, there's no good way to do this.
