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

...I have some other controls. One JButton is labeled: "Set Default Input". A nice control to have. But when the user presses this button, up to 44 JComboBoxes have setSelectedItem () called on them, which fires at least 44 events, which in the action listeners sometimes call setSelectedItem() to make sure their "paired" JComboBox has a consistent selection, and these method calls fire still more events. I have JComboBoxes to insert layers, remove layers, and set the number of layers in the geology. I also have a button to set the inputs to the exact condition they had for a previous saved calculation. All of these involve calling setSelectedItem().

The problem here is that you're not using the ComboBox model. It has a setSelectedItem method that notifies the JComboBox to change it's displayed item. However this doesn't trigger an action event. It will trigger a ListDataEvent which will notify any other objects or models that the value has changed.

Scott has a different problem. He's trying to sync two models, the implicit one created behind each control and his own "document" model. That's more complicated. We solved that problem by extending the models for each type of control. Not particularly complicated really.
