// JToggleButton用哪种监听器

}
监听器代码：
public void createActionListener() {
applistener = new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
requestExecute(e);
}
};
changelistener = new ChangeListener() {
@Override
public void stateChanged(ChangeEvent e) {
JToggleButton toggleBtn = (JToggleButton) e.getSource();
System.out.println(toggleBtn.getText() + " 是否选中: " + toggleBtn.isSelected());
// setMute(jtb.isSelected());
// System.out.println(isMute);
}
};
itemListener = new ItemListener() {
@Override
public void itemStateChanged(ItemEvent e) {
if (e.getStateChange() == ItemEvent.SELECTED) {
// 当JRadioButton被选中时，改变变量engine_selected的值
JRadioButton rBtn = (JRadioButton) e.getSource();
engine_selected = rBtn.getName().trim();
switch (engine_selected) {
case engine_selected_checktext:
System.out.println(((JRadioButton)e.getSource()).getActionCommand());
break;
case engine_selected_offline:
System.out.println(((JRadioButton)e.getSource()).getActionCommand());
break;
case engine_selected_online:
System.out.println(((JRadioButton)e.getSource()).getActionCommand());
break;
case engine_selected_websocket:
System.out.println(((JRadioButton)e.getSource()).getActionCommand());
break;
}
}
}
};
}
执行情况，在鼠标经过、点击、离开时触发了7次：
我只想在鼠标状态完成时触发一次，怎么办？
