本文整理了Java中java.awt.event.KeyEvent.isActionKey()方法的一些代码示例，展示了KeyEvent.isActionKey()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。KeyEvent.isActionKey()方法的具体详情如下：
包路径：java.awt.event.KeyEvent
类名称：KeyEvent
方法名：isActionKey

KeyEvent.isActionKey介绍

[英]Returns whether the key in this event is an "action" key. Typically an action key does not fire a unicode character and is not a modifier key.
[中]返回此事件中的键是否为“操作”键。通常，操作键不会触发unicode字符，也不是修改键。

@Override

    int keyCode = e.getKeyCode();

    //#43617 - don't eat + and -
    //#98634 - and all its duplicates dont't react to space
    if ((c == '+') || (c == '-') || (c==' ')) return; // NOI18N
    if (((modifiers > 0) && (modifiers != KeyEvent.SHIFT_MASK)) || e.isActionKey()) {
      return;
    }

    searchTextField.setText(String.valueOf(stroke.getKeyChar()));
    e.consume();
