    Unhappy I can not redeem the action of a button within a table.

    Good morning,

    Yesterday I was searching the internet a code in which I could place a button inside a table. I found the code below, I am usually able to put the button and made some adjustments to my system, but I'm not able to recover the action of clicking it, can someone help me?




    class BotaoVisualizarTabelaProgramadas extends AbstractCellEditor
            implements TableCellRenderer, TableCellEditor, ActionListener {
     
        JTable table;
        JButton renderButton;
        JButton editButton;
        String text;
     
     
    public BotaoVisualizarTabelaProgramadas(JTable table, int column) {
            super();
            this.table = table;
     
            renderButton = new JButton();
     
            editButton = new JButton();
            editButton.setFocusPainted(false);
            editButton.addActionListener(this);
     
            TableColumnModel columnModel = table.getColumnModel();
            columnModel.getColumn(column).setCellRenderer(this);
            columnModel.getColumn(column).setCellEditor(this);
        }
     
        @Override
        public Component getTableCellRendererComponent(
                JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
            if (hasFocus) {
                renderButton.setForeground(table.getForeground());
                renderButton.setBackground(UIManager.getColor("Button.background"));
            } else if (isSelected) {
                renderButton.setForeground(table.getSelectionForeground());
                renderButton.setBackground(table.getSelectionBackground());
            } else {
                renderButton.setForeground(table.getForeground());
                renderButton.setBackground(UIManager.getColor("Button.background"));
            }
     
           renderButton.setText((value == null) ? "" : value.toString());
            return renderButton;
        }
     
        @Override
        public Component getTableCellEditorComponent(
                JTable table, Object value, boolean isSelected, int row, int column) {
            text = (value == null) ? "" : value.toString();
            return editButton;
        }
     
        @Override
        public Object getCellEditorValue() {
            return text;
        }
     
        @Override
        public void actionPerformed(ActionEvent e) {
            fireEditingStopped();
            System.out.println(e.getActionCommand() + " : " + table.getSelectedRow());
        }
    }

    Default Re: I can not redeem the action of a button within a table.

    The posted code needs import statements to be able to compile and test it.
    If you don't understand my answer, don't ignore it, ask a question.
