java - How can I append to Java KeyEvent modifiers?

Question

I have a KeyEvent whose modifiers I want to change to include the shift key. My current approach is to create a new KeyEvent using information from the old, attempting to add the shift key to the modifiers. However, it doesn't seem to be working.

Is there a better way to do this?

event = new KeyEvent((Component) event.getSource(), KeyEvent.KEY_RELEASED, event.getWhen(), event.getModifiersEx() | KeyEvent.SHIFT_DOWN_MASK, event.getKeyCode(), KeyEvent.CHAR_UNDEFINED);

Answer 1

而不是这个： event = new KeyEvent((Component) event.getSource(), KeyEvent.KEY_RELEASED, event.getWhen(), event.getModifiersEx() | KeyEvent.SHIFT_DOWN_MASK, event.getKeyCode(), KeyEvent.CHAR_UNDEFINED);

我应该这样做： event = new KeyEvent((Component) event.getSource(), event.getID(), event.getWhen(), event.getModifiersEx() | KeyEvent.SHIFT_DOWN_MASK, event.getKeyCode(), KeyEvent.CHAR_UNDEFINED);

请注意，我有 event.getID() 而不是 KeyEvent.KEY_RELEASED。
