如何在cellchange上进行JTable选择所有文本

关于

editorComponent

，我该在哪里初始化此变量？

变量

editorComponent

DefaultCellEditor

代替

class CellEditor extends JTextField implements TableCellEditor

考虑

class CellEditor extends DefaultCellEditor

然后，您可以执行以下操作：

@Overridepublic Component getTableCellEditorComponent(JTable table,        Object value, boolean isSelected, int row, int column) {    JTextField ec = (JTextField) editorComponent;    if (isSelected) {        ec.selectAll();    }    return editorComponent;}

附录：如@
Edoz所建议，并在此完整示例中进行了说明，您可以

selectAll()

JTable table = new JTable(model) {    @Override // Always selectAll()    public boolean editCellAt(int row, int column, EventObject e) {        boolean result = super.editCellAt(row, column, e);        final Component editor = getEditorComponent();        if (editor == null || !(editor instanceof JTextComponent)) { return result;        }        if (e instanceof MouseEvent) { EventQueue.invokeLater(() -> {     ((JTextComponent) editor).selectAll(); });        } else { ((JTextComponent) editor).selectAll();        }        return result;    }};
