Sample scenario:
Headers: Category, Sentences, Boolean
Row1: apple | this is an apple | checkbox
Row2: cat | this is a cat | checkbox
When I ticked the first row. It will System.out.println() the "apple" and "this is an apple."
If you have much time, i would appreciate if there's a code snippet. Thank you.
CheckABunch
is an example that may get you started:
If getColumnClass()
returns Boolean.class
for a column, the default renderer and editor will be a JCheckBox
.
For AbstractTableModel
, your implementation of setValueAt()
must fire the appropriate event, as shown here and here.
Add a TableModelListener
to receive events fired by your model, as shown here.
