Java Swing JTable; Right Click Menu (How do I get it to "select" aka highlight the row)

Short: I need a "right-click event" to highlight the cell row.

I am using a JTable inside a ScrollPane in Java Swing (Netbeans Matisse). I have a MouseClicked event listener on the JTable that does the following:

if (evt.getButton() == java.awt.event.MouseEvent.BUTTON3) {
          System.out.println("Right Click");
          JPopUpMenu.show(myJTable, evt.getX(), evt.getY())
}

The problem is... whenever I execute a right click on the JTable, the row isn't highlighted (I set the selection to rows only btw). I have looked for several setSelected() functions but could not find a suitable one. By default, left clicking automatically highlights the row. How do I set it up for right clicks?

You can create another MouseEvent (example here is in a JTable subclass; processMouseEvent() has protected access, otherwise could use dispatchEvent() method). Takes care of using the modifiers for the selection update.

addMouseListener(new MouseAdapter() {
    @Override public void mousePressed(MouseEvent e) { checkForPopupMenu(e); }
    @Override public void mouseReleased(MouseEvent e) { checkForPopupMenu(e); }
    private void checkForPopupMenu(MouseEvent e) {
        if (e.isPopupTrigger()) {
            processMouseEvent(new MouseEvent(e.getComponent(), e.getID(), e.getWhen(), e.getModifiersEx(), e.getX(), e.getY(), 1, false, MouseEvent.BUTTON1));
            if (getSelectedRowCount() != 0)
                popup.show(e.getComponent(), e.getX(), e.getY());
        }
    }
});
