inputMethodTextChanged 事件在文字改变后触发
The text field fires three events: a key-pressed event, a key-typed event, and a key-released event.
Note :
the key-typed event doesn't have key code information. 含有key charactere信息
key-pressed and key-released events don't have key character information. 含有key code信息
用来检验text changed可以用key-released events. 因为它能够通过getText（）得到textfield中改变后的text. 而 key-pressed event, key-typed event 得到的是改变前的文字
