问题描述
ActionListener和ItemListener都用于使用JCheckBox触发事件?
Both ActionListener and ItemListener are used to fire an event with JCheckBox?
那么,它们之间的区别是什么?在这种情况下,其中一个优先于另一个?
So, what's the difference between them and in which case one of them is preferred to the other?
推荐答案
ItemListener
以及 ActionListener
,如果 JCheckBox
具有相同的行为。
但是,主要区别是 ItemListener
可以通过在复选框上调用 setSelected(true)
来触发。
作为编码惯例,不要同时使用 ItemListener 以及 ActionListener
> JCheckBox ,以避免不一致。
Both ItemListener
as well as ActionListener
, in case of JCheckBox
have the same behaviour.However, major difference is ItemListener
can be triggered by calling the setSelected(true)
on the checkbox.As a coding practice do not register both ItemListener
as well as ActionListener
with the JCheckBox
, in order to avoid inconsistency.
