Question

I have a jTable as from the attached picture

Right click on a row starts a jPopup, with a single item “Thread Stop”.

I would like to return the row number by clicking on this menu item

How to accomplish this?

Thanks.

Answer 1

In your MouseListener where you show your popup, simply get the row and column numbers via the JTable methods:

  table.addMouseListener(new MouseAdapter() {
     @Override
     public void mousePressed(MouseEvent e) {
        Point p = e.getPoint();
        int row = table.rowAtPoint(p);
        int col = table.columnAtPoint(p);

        System.out.printf("row, col: [%d, %d]%n", row, col);

        // show pop-up menu here

     }
  });
