RIght click JPopupMenu on JTabbedPane

RIght click JPopupMenu on JTabbedPane

may help you . I have a JTabbedPane with a custom tab component. I want to be able to right click anywhere on the tab and show a JPopupMenu. The problem I'm having is that there is dead space on each tab where the JPopupMenu does not appear with a right click. I believe it is because I'm attaching the listener to a JPanel that is acting as the Tab Component, but the JPanel isn't "filling" the whole tab. ,
Is there a way to attach a mouse listener to the whole tab?

To fix the issue you can do In the end I "solved" this by hacking around the issue. As Camickr points out, JPopupMenu is pretty buggy. However it is the only Swing popup menu implementation that allows you to have an icon next to each menu element.
My solution was to implement a listener on the jpopupmenu that, if the user put the mouse over the menu, after 3 seconds it would be set to .isVisible(false) if the user did not put the mouse back over the menu within that time.

hop of those help? I am having problems with a popup menu on a JTable and the fact that this JTable allows for Multiple Interval Selection. I'm going to explain in detail my situation, making it as clear as possible, hopefully. , One part of the answer is:
code :
if (tblModel.isSelectedIndex(r)) {
   tblModel.removeSelectionInterval(r, r);
} else {
   tblModel.addSelectionInterval(r, r);

will be helpful for those in need I solve the problem. Firstly thanks to @clamp in this question.
code :
popupForTable.addPopupMenuListener(new PopupMenuListener() {

            public void popupMenuWillBecomeVisible(PopupMenuEvent e) {
                SwingUtilities.invokeLater(new Runnable() {
                    public void run() {
                        Point mousePoint = new Point();
                        mousePoint = MouseInfo.getPointerInfo().getLocation();

                        int rowAtPoint = table.rowAtPoint(SwingUtilities.convertPoint(popupForTable, new Point(0, 0), table));

                        if (rowAtPoint > -1) {
                            table.setRowSelectionInterval(rowAtPoint, rowAtPoint);


            public void popupMenuWillBecomeInvisible(PopupMenuEvent e) {
                // TODO Auto-generated method stub


            public void popupMenuCanceled(PopupMenuEvent e) {
                // TODO Auto-generated method stub



table.addMouseListener(new MouseAdapter() {
            public void mouseReleased(MouseEvent e) {
                int r = table.rowAtPoint(e.getPoint());
                if (r >= 0 && r < table.getRowCount()) {
                    table.setRowSelectionInterval(r, r);
                } else {

                int rowindex = table.getSelectedRow();
                if (rowindex < 0)
                if (e.isPopupTrigger() && e.getComponent() instanceof JTable ) {
                    JPopupMenu popup = popupForTable;
                    popup.show(e.getComponent(), e.getX(), e.getY());
                    table.setRowSelectionInterval(r, r);

should help you out On the deleteItem what you want to do is check inside the MouseListener which mouse button was clicked
code :
 deleteItem.addMouseListener(new MouseAdapter() {
           public void mousePressed(MouseEvent e) {
              if (e.getButton() == MouseEvent.BUTTON3) {
                 // do whatever it is when the right button is pressed
              } else {
                // do whatever it is when the left button is pressed

Hope this helps From Java Doc : isPopupTrigger()
Popup menus are triggered differently on different systems. Therefore, isPopupTrigger should be checked in both mousePressed and mouseReleased for proper cross-platform functionality.
