二个窗体问题!

Question

A窗体和B窗体移动A窗体，B窗体也移动. B窗体的宽度由A窗体控制。 就像QQ音乐一样  点乐库时，显示第二个窗体！

Answer 3

貌似qq音乐没有用过 用的酷狗、、你想让B跟着A移动？、、那么 A窗体的move事件里面 让B跟着移动啊
不过前一段时间研究了一下 关于千千静听的磁铁窗体的效果、、不过貌似并不怎么完美
http://blog.csdn.net/crystal_lz/article/details/7250229
不知道怎么让两个窗体 处于同一置顶级别

Answer 4

谢谢  问题解决了.   在A  窗体中声明一个   静态事件.  然后在B中注册它   A体中执行相应的操作就激活该事件  原满解决
