How to notify a JTable to Update its Model

Question

I'm looking for a pattern to notify my JTable that the Data which are handled in the TableModel have changed. The Idea is that I got a global singleton TreeSet managing the Data. I receive randomly updates on the TreeSet.If any changes are made to the TreeSet the TableModelshould update itself by gathering the new information from the TreeSet.

Observer? Events + Listener? anything else?

Thank you for your help!

ps: A way to update the Model is already implemented and is NOT part of the Question.

You basically answered your own question, observer, event + listeners. A change from the usual: have you tried?

Question was a little confusing, but it sounds like you should be using AbstractTableModel.fireTableDataChanged(), as described here.

You could take a look at Listening for Data Changes

Consider the method fireTableStructureChanged. You can see an example in CustomEditorTableModel

And you can see another in SortingaColumninaJTableComponent
