JComboBox in JTable

I've a JComboBox in 3rd and 4th column of a JTable but I don't know how to get its items...the problem isn't the method to get items but the cast 

JComboBox combo=(JComboBox) jTable1.getColumnModel().getColumn(3).getCellEditor();

Can you help me please?

Solution

  • The JComboBox is wrapped in a CellEditor. You must retrieve the wrapped component, for example when using DefaultCellEditor:

    DefaultCellEditor editor = (DefaultCellEditor)table.getColumnModel().getColumn(3).getCellEditor();
JComboBox combo = (JComboBox)editor.getComponent();
