Key Pressed Event

I want add a KeyEventListener to JButton which responds to Enter key, using following code segment:

   private void jButton3KeyPressed(java.awt.event.KeyEvent evt) {
        if (evt.getKeyCode() == 10) {
           eventRegister();
        }
   }

I pressed space bar instead of enter and the if condition set to true and the eventRegister invoked. Why? How could I prevent this manner?

Solution

    • don't to use KeyListener or MouseListener for JButton or JButtons JComponent, those events are implemented in API, or ButtonsModel, every can be testable, with to consume() of KeyEvent

    • JButton has implemented ENTER and SPACE key as accelator in KeyBindings

    • remove SPACE from KeyBindings, but not suggest that, I'm wouldn'd be confuse users, sure depends of
