windwos编程资源操作2

1

还是和前面的一样 先添加资源

2

3

这是顶级菜单 以及 子菜单

4

然后保存

还是先用前面的部分的代码

然后 开始添加菜单

第一种方式

直接在创建窗口的时候创建菜单

5

6

直接运行

7

菜单直接出来了

第二种方式:

通过传到createwindwoW 函数中 因为这个函数接受一个菜单句柄参数

8

9

因为涉及到句柄 所以就和前面的资源操作一样 需要先导入菜单

10

LoadMenuW函数接受两个参数 第一个是 这个程序的句柄 第二个是菜单资源的名称

11

然后运行

12

第三种:

通过点击 添加菜单

13

14

右键展示子菜单

重新添加一个右键点击消息

15

16

ClientToScreen 函数 将 获取的鼠标坐标转化为 相对于屏幕的鼠标坐标 因为没有转换之前 是相对于工作区 也就是 直接创建的窗口的坐标位置

但是弹出菜单的函数接受坐标 出现的位置是相对于电脑屏幕而言的坐标 所以需要转换

17

18

GetCursorPos 函数直接获取屏幕中的鼠标坐标

给子菜单添加消息

先找到子菜单的ID

19

20

点击子菜单
