Question

I have a swing layout with some labels and a jTable.
On the left side, I have the jTable, and on the right side I have the labels.

I want to set the page up as a master / detail page, where the jTable is the master, while the labels act as details.

I have found a way to get the index from the jTable – my question. What kind of listener can I use to tell if the user selects a row in the table?

Answer 1

You need to get the JTable’s selection model (using getSelectionModel()) and add a ListSelectionListener to this model.

Make sure to use convertRowIndexToModel to convert the index of the selected row to an index in the table model: if the table is sorted or filtered, the view and model indices won’t be the same.
