系统托盘的编程

首先在dlg.h 中定义

#define  WM_ICON_NOTIFY WM_USER+10  //托盘的使用

 

声明一个变量   NOTIFYICONDATA m_nidIconData;

afx_msg LRESULT OnTrayIcon(WPARAM wParam,LPARAM lParam); 

 

然后在dlg.cpp 文件中实现

 

在initialInstance中 加入如下代码

 

m_nidIconData.cbSize = sizeof(NOTIFYICONDATA); m_nidIconData.hWnd = m_hWnd; m_nidIconData.uID = IDR_MAINFRAME; m_nidIconData.uCallbackMessage = WM_ICON_NOTIFY; //m_nidIconData.szInfo = L"SpiritCat"; wcscpy_s(m_nidIconData.szInfo,L"精灵猫"); wcscpy_s(m_nidIconData.szTip,L"SpiritCat"); wcscpy_s(m_nidIconData.szInfoTitle,L"喵~~"); //气泡维持时间 m_nidIconData.uTimeout = 5000; m_nidIconData.hIcon = LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_MAINFRAME)); m_nidIconData.uFlags = NIF_ICON|NIF_MESSAGE|NIF_TIP|NIF_INFO; //下面这行加上才能出现气泡 m_nidIconData.dwInfoFlags = NIIF_INFO; Shell_NotifyIcon(NIM_ADD,&m_nidIconData); 

添加消息映射

 

ON_MESSAGE(WM_ICON_NOTIFY,OnTrayIcon) 

窗口过程实现代码

 

LRESULT CEnumeProgressDlg::OnTrayIcon( WPARAM wParam,LPARAM lParam ) { if (IDR_MAINFRAME != wParam) { return TRUE; } switch (lParam) { case WM_LBUTTONDBLCLK: if (m_bTrayShow) { ShowWindow(SW_HIDE); m_bTrayShow=FALSE; } else { ShowWindow(SW_NORMAL); SetForegroundWindow(); m_bTrayShow = TRUE; } break; case WM_RBUTTONDOWN: CMenu popUpMemu; popUpMemu.LoadMenu(IDR_MENU1); CPoint point; GetCursorPos(&point); popUpMemu.TrackPopupMenu(TPM_LEFTALIGN|TPM_TOPALIGN,point.x,point.y,this); break; } return 0; }
