[HELP] How to addTableModelListener to DefaultTableModel from Other Class(JDialog)?
Dear All,
I have 2 JDialog class, "Data" & "Student". on "Data JDialog Class" have a jTable with DefaultTableModel and implements TableModelListener to calculate grade of student. on "Student JDialog Class" just have a jTable with DefaultTableModel and contain a data of student.
The Application process is "Data JDialog class" take a student name and class from "Student JDialog Class" then user input the score of student in score Column on "Data JDialog Class" and calculate Pass or Fail.
The Question is :
1. How to addTableModelListener & removeTableModelListener to DefaultTableModel on "Data JDialog Class" from "Student JDialog Class"?
i have try to add "addTableModelListener(this)" syntax on Constructor "Data JDialog Class" but that is cause can't take name and class from "Student JDialog Class" because error on use method "addRow(Object[] rowData)" as a result of calling the event handler repeatedly from within the event handler.
Please it's support,
Thanks.
