MFC：程序的托盘显示

介绍

关键技术，API函数Shell_NotifyIcon，具体查看msdn吧

实现的主要代码

#define MY_TRAY_ICON_ID (1)/
//其他代码：略BEGIN_MESSAGE_MAP(CTestShowTrayDlg, CDialogEx)//...ON_MESSAGE(WM_MY_TRAY_ICON, &CTestShowTrayDlg::OnMessageTrayIcon)/
END_MESSAGE_MAP()void CTestShowTrayDlg::ShowTrayIcon()
{NOTIFYICONDATA nid = { 0 };nid.cbSize = sizeof(NOTIFYICONDATA);nid.hWnd = this->m_hWnd;nid.uID = MY_TRAY_ICON_ID;nid.uFlags = NIF_ICON | NIF_MESSAGE | NIF_TIP;nid.uCallbackMessage = WM_MY_TRAY_ICON; //托盘图标中消息回调，如鼠标左键、右键等等nid.hIcon = m_hIcon;_tcscpy_s(nid.szTip, _T("测试托盘显示图标"));Shell_NotifyIcon(NIM_ADD, &nid); //在托盘区添加图标
}void CTestShowTrayDlg::DelTrayIcon()
{NOTIFYICONDATA nid = { 0 };nid.cbSize = sizeof(NOTIFYICONDATA);nid.hWnd = this->m_hWnd;nid.uID = MY_TRAY_ICON_ID;Shell_NotifyIcon(NIM_DELETE, &nid); //在托盘区移除图标
}LRESULT CTestShowTrayDlg::OnMessageTrayIcon(WPARAM wParam, LPARAM lParam)
{if (wParam != MY_TRAY_ICON_ID)//wParam传入nid.uID{return TRUE;}switch (lParam){case WM_LBUTTONUP:case WM_LBUTTONDBLCLK:{OnMenuShowWindow();break;}case WM_RBUTTONUP://右键起来时弹出快捷菜单，这里只有一个“关闭”{CPoint ptCursor;::GetCursorPos(&ptCursor);//从资源中加载菜单CMenu mTrayMenu;mTrayMenu.LoadMenu(MAKEINTRESOURCE(IDR_MENU_TRAY));CMenu* pMenu = mTrayMenu.GetSubMenu(0);if (pMenu) pMenu->TrackPopupMenu(TPM_LEFTALIGN, ptCursor.x, ptCursor.y, this);mTrayMenu.DestroyMenu(); //资源回收break;}}return TRUE;
}//显示主界面
void CTestShowTrayDlg::OnMenuShowWindow()
{this->ShowWindow(SW_SHOWNORMAL);this->SetForegroundWindow();this->SetActiveWindow();
}//退出
void CTestShowTrayDlg::OnMenuExit()
{DelTrayIcon();CDialogEx::OnCancel();
}void CTestShowTrayDlg::OnOK()
{// TODO:  在此添加专用代码和/或调用基类//屏蔽ESC/Enter//CDialogEx::OnOK();
}void CTestShowTrayDlg::OnCancel()
{this->ShowWindow(SW_HIDE);//屏蔽ESC/Enter//CDialogEx::OnCancel();
}
