MFC 添加系统栏图标

系统栏图标添加规则:(以CDialog为例)

1, Dialog类中加入显示系统栏图标的变量 NOTIFYICONDATA m_NotifyIcon;

2, Dialog类中加入消息处理函数afx_msg LRESULT OnNotifyIcon(WPARAM wParam, LPARAM lParam) 来响应对系统栏图标的响应。

3, BEGIN_MESSAGE_MAP(), END_MESSAGE_MAP()中间添加消息处理映射ON_MESSAGE(WM_NC, &CMyCPL2Dlg::OnNotifyIcon)

4, Dialog类的初始化函数OnInitDialog()中添加系统栏图标初始化:

m_NotifyIcon.cbSize = sizeof(NOTIFYICONDATA);//

m_NotifyIcon.hIcon = AfxGetApp()->LoadIcon(IDI_MYCPLDLG);//图标图案

m_NotifyIcon.hWnd = m_hWnd;//

lstrcpy(m_NotifyIcon.szTip, "UVC Control");//鼠标指示时显示提示

m_NotifyIcon.uCallbackMessage = WM_NC;//消息响应函数

m_NotifyIcon.uFlags = NIF_ICON | NIF_TIP | NIF_MESSAGE;//图标类型

Shell_NotifyIcon(NIM_ADD, &m_NotifyIcon);//系统栏添加图标

5, 添加消息响应函数

LRESULT CMyCPL2Dlg::OnNotifyIcon(WPARAM wParam, LPARAM lParam)

{

              if ((lParam == WM_LBUTTONDOWN)) // Lbutton down

              {

                  ModifyStyleEx(0,WS_EX_TOPMOST);

                  ShowWindow(SW_SHOW);   // Show Main Window

                  //Shell_NotifyIcon(NIM_DELETE, &NotifyIcon);

          }

     }

6, 如果有需要,可以在关闭对话框时删除系统栏图标。添加函数DestroyWindow()

BOOL CMyCPL2Dlg::DestroyWindow()

{

              // TODO: Add your specialized code here and/or call the base class

              Shell_NotifyIcon(NIM_DELETE, &m_NotifyIcon);   // Delete Icon

              return CDialog::DestroyWindow();

}
