有没有其他方法比如我想编一个菜单控件
怎样为某个菜单项设置热键(该菜单是用API动态创建的)
方法实现,对于进程级可以将钩子函数函数编写进模块中再挂钩实现,对于系统级的热键,需要将钩子函数写入dll中,再进行挂钩实现
UP! :)
怎么为API动态创建的菜单设置热键?
我不知道啊!
假如我是用那种用PictureBox做XP菜单的话,怎么办?
那时无法接到键盘消息
Windows里热键是靠消息循环实现的。除非你更新热键表,否则难以实现,只能自己写代码判断。
参考API:
LoadAccelerators, CopyAcceleratorTable, CreateAcceleratorTable, DestroyAcceleratorTable

因为我的名字读起来有点像910
而且以拼音首字母分别是zyl
所以叫zyl910
