如何创建组合框actionListener? [英] How to create a combo box actionListener?

问题描述

如何创建组合框动作侦听器? 到目前为止，我有以下内容:

How do I create a combo box action listener? I have the following so far:

myCombo = new JComboBox();
myCombo.addActionListener();

我不确定该如何进行，似乎与按钮所用的有所不同.

I am not sure how to proceed, it seems that it is different from the one used for the buttons.

推荐答案

尝试一下:

 myCombo.addActionListener(new actionListener() {
   public void actionPerformed(ActionEvent eventSource) {
   JComboBox combo = (JComboBox) myCombo.getSource();
   Object selected = combo.getSelectedItem();
   if("whatever...") {

}
}
}
);
