copied!<p>It's an interesting question, because it highlights missing api on JComponent :-) </p> <p>As we all know, the recommended way to register popupMenus is to use the componentPopupMenu property. Related api is </p> <pre><code> void setComponentPopupMenu(JPopupMenu); JPopupMenu getComponentPopupMenu(); Point getPopupLocation(MouseEvent); </code></pre> <p>what is missing (and actually needed for this requirement) is</p> <pre><code>JPopupMenu getComponentPopupMenu(MouseEvent); </code></pre> <p>this lack is all the more annoying, as the getPopupLocation is called (by AWTEventHelper deep in the LAF) <em>after</em> getComponentPopup(). So there's no leeway for a hack like storing the last mouse event which might have triggered the popup and then decide which/if to return popup. And returning null for the location will only result in showing it at the mouse location</p> <p>The only (dirty) hack (around my utter reluctance to get my hands dirty with a MouseListener ;-) is to override getComponentPopup and decide there whether or not to return it based on current mouse position</p> <pre><code> table = new JTable(model) { /** * @inherited <p> */ @Override public JPopupMenu getComponentPopupMenu() { Point p = getMousePosition(); // mouse over table and valid row if (p != null && rowAtPoint(p) >= 0) { // condition for showing popup triggered by mouse if (isRowSelected(rowAtPoint(p))) { return super.getComponentPopupMenu(); } else { return null; } } return super.getComponentPopupMenu(); } }; </code></pre> <p>the side-effect is that popup showing isn't triggered by keyboard as long as the mouse is anywhere above the table, which might or not be a problem.</p>
