1、获取鼠标位置(在屏幕的位置)
CPoint m_mouse;
GetCursorPos(&m_mouse);
2、 屏幕转化为客户端(控件的相对位置)& 客户端位置转化为屏幕位置
ClientToScreen(this->m_hwnd,m_mouse); //客户端位置转化为屏幕位置
ScreenToClient(this->m_hwnd,m_mouse) ; //屏幕转化为客户端
3、获取控件关于在屏幕的位置
CRect rc
GetWindowRect(&rc);
4、检测鼠标的action的方式多,自己用的多的是msdn上介绍的callback的鼠标钩子(低级钩子)函数来实现
1> 、对鼠标进行的几个全局变量进行声明:
将这部分放置在C++类的外部
/*
全局变量和全局函数定义
设定一个鼠标低级钩子变量
*/
HHOOK mouse_Hook ;
LRESULT CALLBACK LowLevelMouseProc ( INT nCode,
WPARAM wParam,
LPARAM lParam
);
BOOL UninstallHook(); //卸载
BOOL InstallHook(); //安装
2>、在构造函数中初始化
1 mouse_Hook=NULL; //将钩子NULL
3>、在初始化函数中安装Hook
1 InstallHook()
4>、在析构函数中添加
UninstallHook()
5>、 在当前cpp的类外中定义声明的三个函数
1 BOOL InstallKbHook( )
2 {
3
4 if (mouse_Hook) UninstallHook();
5 mouse_Hook = SetWindowsHookEx(WH_MOUSE_LL,
6 (HOOKPROC)(LowLevelMouseProc), AfxGetApp()->m_hInstance, NULL);
7
8 return( mouse_Hook != NULL);
9 }
10
11 BOOL UninstallHook()
12 {
13
14 BOOL jud = FALSE;
15 if (mouse_Hook) {
16 jud= UnhookWindowsHookEx(mouse_Hook );
17 mouse_Hook = NULL; //set NULL
18 }
19
20 return jud;
21 }
22
23 LRESULT CALLBACK LowLevelMouseProc (INT nCode, WPARAM wParam, LPARAM lParam)
24 {
25 CPoint _mousepoint;
26 MSLLHOOKSTRUCT *pkbhs = (MSLLHOOKSTRUCT *)lParam;
27 switch (nCode)
30 {
31
32 case HC_ACTION:
33 {
34 //鼠标左击
35 if(wParam == WM_LBUTTONDOWN||wParam == WM_RBUTTONDOWN||wParam == WM_MBUTTONDOWN||wParam ==WM_LBUTTONUP||wParam ==WM_RBUTTONUP||wParam == WM_MBUTTONUP){
36 //获取鼠标的位置,并进行必要的判断
37
38 //鼠标右键按下
39 if(Mmdlg!=NULL){
40 if( Mmdlg->setingmenu!=NULL&& Mmdlg->bo_back!=1)
41 {
42 //如果鼠标不在当前客户端位置之内
43 GetCursorPos(&_mousepoint);
44 CRect m_crect;
45 //Mmdlg->setingmenu->GetClientRect(m_crect);
46 Mmdlg->setingmenu->GetWindowRect(m_crect);
47 //ScreenToClient(Mmdlg->setingmenu->m_hWnd,&m_crect);
48 if(m_crect.bottom>_mousepoint.y && m_crect.top<_mousepoint.y &&
49 m_crect.left<_mousepoint.x && m_crect.right >_mousepoint.x
50 ){
51 ; //啥也不干
52 }
53 else{
54 delete [] Mmdlg->setingmenu;
55 Mmdlg->setingmenu=NULL;
56 }
57 }
58 Mmdlg->bo_back=0;
59 }
60 }
61 }
62 default: break;
63 }
64
65 return CallNextHookEx (NULL, nCode, wParam, lParam);
66 }
编程是一种快乐,享受代码带给我的乐趣!!!
