java - JTable -> TableModeListener

Question

I have this JTable having a DefaultTableModel as its model. On the table I have several swing component, JComboBox and JCheckBox, set on a particular column via DefaultCellEditor and DefaultCellRenderer. The TableModelListener was added to the table to capture changes on editable columns. The rest of the columns will display details of the selected component, i.e. item code -> item price, item count, item classification,etc.

I have this problem wherein if the selectedItem of the JComboBox(itemCode) changes, the items of the other JComboBox(itemClassification) changes. But together with the change of the other JComboBox I need to display the item price on the same table. This change refires the valueChanged method which makes an infinite loop of valueChanged.

How can I get rid of the infinite loop thing?

Answer 1

You could remove the listener when making changes from within the listener itself, and then re-add it when done with changes. Or you could give the Listener a boolean property that activates and deactivates the listener code, and set it appropriately from within the listener.
