托盘图标操作类

先上测试图

托盘也是属于比较常用的了

其实托盘操作很简单的，基本都是通过Shell_NotifyIcon API进行操作

主要是它的第二个参数

Shell_NotifyIcon原型：

1 BOOL Shell_NotifyIcon(
2   _In_ DWORD           dwMessage,
3   _In_ PNOTIFYICONDATA lpdata
4 );

第一个参数是要对托盘进行的操作类型，第二个参数是个结构体。

NOTIFYDATA结构体原型

 1 typedef struct _NOTIFYICONDATA {
 2   DWORD cbSize;
 3   HWND  hWnd;
 4   UINT  uID;
 5   UINT  uFlags;
 6   UINT  uCallbackMessage;
 7   HICON hIcon;
 8   TCHAR szTip[64];
 9   DWORD dwState;
10   DWORD dwStateMask;
11   TCHAR szInfo[256];
12   union {
13     UINT uTimeout;
14     UINT uVersion;
15   };
16   TCHAR szInfoTitle[64];
17   DWORD dwInfoFlags;
18   GUID  guidItem;
19   HICON hBalloonIcon;
20 } NOTIFYICONDATA, *PNOTIFYICONDATA;

其实我是从MSDN里复制的 - - ，结构体成员一看就知道什么意思，深入了解还是参考MSDN吧，它更加详细官方

我写了个类把基本操作写好了，没写挂接时间，因为我感觉暂时用不到，用到了再写吧。

TrayClass.h

 1 #pragma once
 2 #include <Windows.h>

 4 class Tray
 5 {
 6 private:
 7     NOTIFYICONDATA m_msgNotify;
 8     HWND m_hwnd;
 9 
10 public:
11     Tray();
12     ~Tray();
13     // 寻找托盘窗口句柄
14     HWND FindTrayWnd(void);
15     // 寻找托盘句柄 针对win7及以上系统(含有小三角隐藏图标)
16     HWND FindNotifyIconOverflowWindow(void);
17     // 创建托盘(调用者窗口句柄，图标数据NULL为当前图标，提示消息)
18     BOOL Create(HWND hwnd, LPVOID lpszIcon, LPCWCHAR msg);
19     // 修改消息
20     BOOL SetTip(LPCWCHAR msg);
21     // 气泡提示
22     BOOL SetBubble(LPCWCHAR tipTitle, LPCWCHAR tipContent, DWORD tipIcon=0);
23     
24 };

42         lstrcpyn(Tray::m_msgNotify.szTip, msg, lstrlen(msg) + 1);
43         return Shell_NotifyIcon(NIM_ADD, &(Tray::m_msgNotify));
44     }
45     return FALSE;
46 }
47 
48 BOOL Tray::SetTip(LPCWCHAR msg)
49 {
50     lstrcpyn(Tray::m_msgNotify.szTip, msg, 128);
51     return Shell_NotifyIcon(NIM_MODIFY, &(Tray::m_msgNotify));
52 }
53 
54 BOOL Tray::SetBubble(LPCWCHAR tipTitle, LPCWCHAR tipContent, DWORD tipIcon)
55 {
56     Tray::m_msgNotify.dwInfoFlags = tipIcon;
57     // 规定提示标题长度限制64
58     lstrcpyn(Tray::m_msgNotify.szInfoTitle, tipTitle, 64);
59     // 规定提示内容长度限制256
60     lstrcpyn(Tray::m_msgNotify.szInfo, tipContent, 256);
61     return Shell_NotifyIcon(NIM_MODIFY, &(Tray::m_msgNotify));

Win10下测试也是Ok的，基本上是仿照易语言的精易模块写的，他给了我很大的帮助，感谢！

有一点不明白，他那个刷新图标循环没看懂，怎么看都像死循环。。。
