Get row values of ticked checkbox in jtable
10,201
Solution 1
CheckABunch
is an example that may get you started:
If
getColumnClass()
returnsBoolean.class
for a column, the default renderer and editor will be aJCheckBox
.For
AbstractTableModel
, your implementation ofsetValueAt()
must fire the appropriate event, as shown here and here.Add a
TableModelListener
to receive events fired by your model, as shown here.
Solution 2
JTable get cehckbox value when check box is checked:-
table.getModel().addTableModelListener(new TableModelListener() {
@Override
public void tableChanged(TableModelEvent e) {
for(int i=0;i<table.getModel().getRowCount();i++)
{
if ((Boolean) table.getModel().getValueAt(i,0))
{
System.out.println(">\t"+table.getSelectedRow());
break;
}
}
}
});

class TableModel extends AbstractTableModel { Object rowData[][] = DataAccess.getSentences(); String columnNames[] = {"Category", "Sentences", "Boolean"}; public int getColumnCount() { return columnNames.length; } public String getColumnName(int column) { return columnNames[column]; } public int getRowCount() { return rowData.length; } public Object getValueAt(int row, int column) { return rowData[row][column]; } public Class getColumnClass(int column) { return (getValueAt(0, column).getClass()); } public void setValueAt(Object value, int row, int column) { rowData[row][column] = value; } public boolean isCellEditable(int row, int column) { return (column >= 2); } }
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.
