VC实现将对话框最小化到系统托盘
1.minisysDlg.h头文件设置:
1)public:
void setTray();//设置托盘
NOTIFYICONDATA nid;//NOTIFYICONDATA结构包含了系统用来处理托盘图标的信息
2)protected:
// Generated message map functions
//{{AFX_MSG(CminisysDlg)
afx_msg LRESULT onShowTask(WPARAM wParam,LPARAM lParam);
//}}AFX_MSG
2.minisysDlg.cpp实现设置:
1) #define WM_SHOWTASK (WM_USER + 1) //设置响应消息
2) BEGIN_MESSAGE_MAP(CminisysDlg, CDialog)
//{{AFX_MSG_MAP(CminisysDlg)
ON_MESSAGE(WM_SHOWTASK,onShowTask)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
3)最小化菜单响应
void CminisysDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
if(nID==SC_MINIMIZE)
{
setTray();//最小化到托盘
}
}
4)托盘函数
void CminisysDlg::setTray()
{
nid.cbSize=(DWORD)sizeof(NOTIFYICONDATA);
nid.hWnd=this->m_hWnd;
nid.uID=IDR_MAINFRAME;
nid.uFlags=NIF_ICON|NIF_MESSAGE|NIF_TIP;
nid.uCallbackMessage=WM_SHOWTASK;//自定义的消息名称
nid.hIcon=LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_MAINFRAME));
strcpy(nid.szTip,"ClientTracer"); //信息提示条
Shell_NotifyIcon(NIM_ADD,&nid); //在托盘区添加图标
ShowWindow(SW_HIDE); //隐藏主窗
}
5)消息函数
LRESULT CminisysDlg::onShowTask(WPARAM wParam,LPARAM lParam)
{
//wParam接收的是图标的ID,而lParam接收的是鼠标的行为
if(wParam!=IDR_MAINFRAME) return 1;
switch(lParam)
{
case WM_RBUTTONUP://右键起来时弹出快捷菜单,这里只有一个“关闭”
{
LPPOINT lpoint=new tagPOINT;
::GetCursorPos(lpoint);//得到鼠标位置
CMenu menu;
menu.CreatePopupMenu();//声明一个弹出式菜单
//增加菜单项“关闭”,点击则发送消息WM_DESTROY给主窗口,将程序结束。
menu.AppendMenu(MF_STRING,WM_DESTROY,"退出");
//确定弹出式菜单的位置
SetForegroundWindow();//弹出菜单失去焦点后自动消失
menu.TrackPopupMenu(TPM_LEFTALIGN,lpoint->x,lpoint->y,this);
//资源回收
HMENU hmenu=menu.Detach();
menu.DestroyMenu();
delete lpoint;
}
break;
case WM_LBUTTONDBLCLK://双击左键的处理
{
Shell_NotifyIcon(NIM_DELETE,&nid);//删除托盘图标
ShowWindow(SW_SHOWNORMAL);//显示主窗口
//this->SetWindowPos(&wndTopMost,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);//使窗口总是在最前面
}
break;
}
return 0;
}
6)继承WM_DESTROY:
void CminisysDlg::OnDestroy()
{
CDialog::OnDestroy();
// TODO: Add your message handler code here
Shell_NotifyIcon(NIM_DELETE,&nid); //退出程序后删除托盘图标
}
7) 映射ON_SIZE:
void CminisysDlg::OnSize(UINT nType, int cx, int cy)
{
CDialog::OnSize(nType, cx, cy);
// TODO: Add your message handler code here
if(nType == SIZE_MINIMIZED)
{
ShowWindow(SW_HIDE); // 当最小化市,隐藏主窗口
}
}
3.说明:代码均是添加到现有MFC框架代码!
