Re: How to distinguish between user selection and programatic selection with ListSelectionListener

OK. So here's the real answer : use JComboBox().getModel().setSelectedItem(..). Use JList.getListModel().setSelectedIndex(..). Buttons only fire actions on doClick(), you should using setSelected(), what's the issue there? Do you need a hidden button in the group to clear the selection, do you need to set the selected state for all of the buttons rather than running doClick() on just one, or is there some other issue??

Ok.. this was the simple thing that I was missing - that going straight to the model would avoid *some* of the events being fired. Do all Swing components work this way? Also sometimes the event that I'm interested in is not an Action event. I don't think list selection events work this way... (the subject of this thread). I have some experiments to do.

Just checking the source... the ListModel does not have a setSelectedIndex() method. Even the JList selection methods are delegated directly to the ListSelectionModel which fires the related events. It seems there is no way to avoid ListSelectionEvents.

Thanks for clearing this up. I'm not sure yet that it will solve all of the related issues, but it will solve some. I will post back if I find a particular case in my application that skipping the control an going direct to the model does not work for.
