Кнопки в JFrame, доступ к методам в AbstractTableModel

У меня есть Table, который распространяется JPanel, MyTableModel extends AbstractTableModel. Я хочу добавить в JFrame кнопку ActionPerformed и вызвать deleteRow() от MyTableModel в выбранной строке. Как я должен это делать ?Кнопки в JFrame, доступ к методам в AbstractTableModel

EDIT:

, когда я добавить кнопку в рамке из палитры и добавить из контекстного меню на кнопке

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { 
    String text1 = titleTextField.getText(); 
    String text2 = authorTextField.getText(); 
    int text3 = Integer.parseInt(yearTextField.getText()); 
    JTable table = table1.getTable(); 
      MyTableModel model = (MyTableModel) table.getModel(); 

      System.out.println(text1 + text2 +text3); 
      model.addRow(new Book(model.list.size(), text1, text2, text3)); 
}

Я получаю Null Pointer Exc на -> JTable таблицы = table1.getTable() ; -> возвращение нулевой

UPDATE 3:

'Table' не может быть скомпилирован без' Book' класса –

То же с '' Butt' и DataInterface'. Вот почему я создал свой собственный код в первую очередь –

Так как до того, как вы не смогли скомпилировать код, я собираюсь спать. –

Потому что я не вижу actionPerformed метод в любом месте вашего кода, я собираюсь предположим, что вы не знаете, как добавить код в NetBeans (потому что некоторые части не могут быть изменены). Это было бы просто глупо предположить, что вы не имеете ни малейшего представления о том, как программировать код события ;-) Так вот основные шаги в Netbeans

правой кнопкой мыши на кнопке, которую вы хотите выполнить действие на ,
Выберите Event -> Action -> actionPerformed
Вы должны увидеть что-то вроде этого генерируется в исходном коде вблизи нижнего
```
private void jButton1ActionPerformed(java.awt.event.ActionEvent e) { 

} 
```
Введите код в этом методе для удаления строки

Также похоже, что ваши JTable и TableModel находятся в другом классе чем кнопки. Что вам нужно сделать, так это иметь геттер для таблицы в классе Table.После того, как вы есть, что вы можете сделать что-то вроде этого

private void jButton1ActionPerformed(java.awt.event.ActionEvent e) { 
    JTable table = table1.getTable(); 
    MyTableModel model = (MyTableModel)table.getModel(); 
    model.removeRow(...); 
}

Испытано сам, с более коротким кодом. Он работает нормально. Не ClassCastException

Я знаю его, у меня нет доступа table1.deleteRow (строка); – kxyz

Посмотрите на вторую часть ответа –

Я получаю исключение в потоке «AWT-EventQueue-0» java.lang.ClassCastException: net.kxyz.Table $ MyTableModel не может быть отброшен в net.kxyz.MyTableModel – kxyz

Предполагая, что вы имеете в виду removeRow (целое), как о -

jbutton1.addActionListener(new ActionListener(){ 
    public void actionPerformed(ActionEvent e) { 
     table.deleteRow(row); 
    } 
});

У меня нет доступа к table.deleteRow(), потому что этот метод находится в MyTableModel – kxyz

Кнопки в JFrame, доступ к методам в AbstractTableModel
