[原创] MessageLine控件, 告别MessageBox的烦扰
[Original] MessageLine : Say Goodbye to MessageBox
1. I hate MessageBox, indeed. And you?
有木有觉得程序中经常弹出的MessageBox很烦? 至少我很讨厌这个, 所以自己写了一个MessageLine控件取代MessageBox.
2. MessageLine 控件关键属性
1: a. PreTitle : string, MessageLine的标题;
2: b. MessageBody : string, MessageLine的消息内容; (使用的时候最好双向绑定)
3: c. Duration: uint, 每条消息显示的时间;
效果图:
