MFC 托盘图标 NOTIFYICONDATA 封装class

说明： 我只是把原本的NOTIFYICONDATA结构体创建方式进行一次封装，还有大量可扩展空间 诸位自行研究 我这里只是一个简易的框架

CMainFrame头文件中需要添加的对象

//托盘功能
#define	WM_SYSTEMTRAY WM_USER + 0x0010
#include "NotifyIcon.h"
class CMainFrame
{
//...CNotifyIcon NotifyIcon;afx_msg LRESULT OnSystemTray(WPARAM wParam, LPARAM lParam);
//...}

创建方式

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{//.....//设置系统托盘HICON hicon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);NotifyIcon.InitNotify(this, hicon, WM_SYSTEMTRAY);return 0;
}

当然了还有要添加消息

BEGIN_MESSAGE_MAP(CMainFrame, CFrameWndEx)
//....ON_MESSAGE(WM_SYSTEMTRAY, &CMainFrame::OnSystemTray)
//.....
END_MESSAGE_MAP()afx_msg LRESULT CMainFrame::OnSystemTray(WPARAM wParam, LPARAM lParam)
{//wParam接收的是图标的ID，而lParam接收的是鼠标的行为 NotifyIcon.OnSystemTray((UINT)wParam, lParam);return 0;
}

头文件定义

#pragma onceclass CNotifyIcon :public NOTIFYICONDATA
{
public:CNotifyIcon();virtual ~CNotifyIcon();
protected:CWnd* pWndParent;
public:void InitNotify(CWnd* pWnd,HICON hicon, UINT MsgID);LRESULT OnSystemTray(UINT wParam, LPARAM lParam);
protected:// 右键单击消息virtual void OnRButtonDown();// 左键单击virtual void OnLButtonDown();// 左键双击virtual void OnLButtonDblClk();
};
