Right-click MouseListener on whole JTable component

Question

I'm using Netbeans and I've designed a window with JTable and added MouseEvent listener on JTable component and added this code:

private void productsTableMousePressed(java.awt.event.MouseEvent evt) {
    if(evt.isPopupTrigger()) {
        tablePopupMenu.setLocation(evt.getXOnScreen(), evt.getYOnScreen());
        tablePopupMenu.setVisible(true);
        System.out.println("Fired!");
    }
}

private void productsTableMouseReleased(java.awt.event.MouseEvent evt) {
    if(evt.isPopupTrigger()) {
        tablePopupMenu.setLocation(evt.getXOnScreen(), evt.getYOnScreen());
        tablePopupMenu.setVisible(true);
    }
}

But it works only when I click on some cells. I want to get it working on whole JTable area. How?

Answer 1

Assuming your table is inside a JScrollPane, it may not cover the entire viewport. To ensure the whole area of your viewport is covered, call setFillsViewportHeight(true) on your table.

Answer 2

The MouseListener will work on all cells. I don't know if you should be using the setLocation(...) method.

See Bringing Up a Popup Menu for example code.

Or a better approach is to use:

table.setComponentPopupMenu(...);
