Mnemonics are those underlined letters that you see in labels and buttons that when activated via the ALT key + the letter, will activate that label/button.
However, when a JTable is included in the user interface and has editing capabilities enabled, you may be surprised that instead of activing a button by pressing ALT + key on the keyboard, the JTable activates editing mode.
How to fix it then? You need to override the processKeyBinding() method of the JTable class. Do it like this

JTable table = new JTable() { protected boolean processKeyBinding(KeyStroke ks, KeyEvent e, int condition, boolean pressed) { if (checkInvalidKeys(e)) { return false; } return super.processKeyBinding(ks, e, condition, pressed); } private boolean checkInvalidKeys(KeyEvent ke) { if (ke.isAltDown()) return false; else return true; } }); |
This solution was from a forum called Java.net and fixed this mnemonic problem when a JTable with cell editors is present in the same user interface area.
