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：

BOOL Shell_NotifyIcon(
  _In_ DWORD           dwMessage,
  _In_ PNOTIFYICONDATA lpdata
);

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

typedef struct _NOTIFYICONDATA {
  DWORD cbSize;
  HWND  hWnd;
  UINT  uID;
  UINT  uFlags;
  UINT  uCallbackMessage;
  HICON hIcon;
  TCHAR szTip[64];
  DWORD dwState;
  DWORD dwStateMask;
  TCHAR szInfo[256];
  union {
    UINT uTimeout;
    UINT uVersion;
  };
  TCHAR szInfoTitle[64];
  DWORD dwInfoFlags;
  GUID  guidItem;
  HICON hBalloonIcon;
} 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

#pragma once
#include <Windows.h>

class Tray
{
private:
    NOTIFYICONDATA m_msgNotify;
    HWND m_hwnd;

public:
    Tray();
    ~Tray();
    // 寻找托盘窗口句柄
    HWND FindTrayWnd(void);
    // 寻找托盘句柄 针对win7及以上系统(含有小三角隐藏图标)
    HWND FindNotifyIconOverflowWindow(void);
    // 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)
    BOOL Create(HWND hwnd, LPVOID lpszIcon, LPCWCHAR msg);
    // 修改消息
    BOOL SetTip(LPCWCHAR msg);
    // 气泡提示
    BOOL SetBubble(LPCWCHAR tipTitle, LPCWCHAR tipContent, DWORD tipIcon=0);
    
};

TrayClass.cpp

#include "TrayClass.h"

Tray::Tray()
{
    Tray::m_msgNotify = { 0 };
    Tray::m_msgNotify.cbSize = sizeof(Tray::m_msgNotify);

{
    if (IsWindow(hwnd))
    {
        Tray::m_hwnd = hwnd;
        Tray::m_msgNotify.hWnd = hwnd;
        Tray::m_msgNotify.uFlags = NIF_ICON | NIF_TIP | NIF_INFO | NIF_MESSAGE;
        Tray::m_msgNotify.hIcon = (HICON)SendMessage(hwnd, 127, 0, 0);//
        Tray::m_msgNotify.uID = 1;
        Tray;; m_msgNotify.uTimeout = 10000;
        lstrcpyn(Tray::m_msgNotify.szTip, msg, lstrlen(msg) + 1);
        return Shell_NotifyIcon(NIM_ADD, &(Tray::m_msgNotify));
    }
    return FALSE;
}

BOOL Tray::SetTip(LPCWCHAR msg)
{
    lstrcpyn(Tray::m_msgNotify.szTip, msg, 128);
    return Shell_NotifyIcon(NIM_MODIFY, &(Tray::m_msgNotify));
}

BOOL Tray::SetBubble(LPCWCHAR tipTitle, LPCWCHAR tipContent, DWORD tipIcon)
{
    Tray::m_msgNotify.dwInfoFlags = tipIcon;
    // 规定提示标题长度限制64
    lstrcpyn(Tray::m_msgNotify.szInfoTitle, tipTitle, 64);
    // 规定提示内容长度限制256
    lstrcpyn(Tray::m_msgNotify.szInfo, tipContent, 256);
    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。。。
