how to emit signal in a static function ?

[cxl2253]

thanks all . I found that it's impossible to emit the signal in static function .Now I play the trick. I not emit the signal to inform the object which is out of the thread, I directly implement the code that shouble be in SLOT range. Because it is non-static member function of class ,i have to load it into static function.I used the trick mentioned before, used "this" address .
thanks all again.

Other more, if want to use QApplication.poseEvent(), what should i do ? in BCB,I can just write like that .

/////////////cfrmmain.h///////
enum { NM_STORESCP_CALLBACK = WM_USER + 100 }; 
void __stdcall MyStoreScpCallback(T_StoreProgress* progress, LPCSTR filename);
class TfrmMain : public TForm
{
  BEGIN_MESSAGE_MAP
        VCL_MESSAGE_HANDLER(NM_STORESCP_CALLBACK, TMessage,  OnStoreSCPCallback);
    END_MESSAGE_MAP(TForm);
}
//////////////cfrmmain.cpp////////
void __stdcall MyStoreScpCallback(T_StoreProgress* progress, LPCSTR filename)
{
    ///emit the message user defined :in QT ,how to postEvent and get the receive ????
    SendMessage(Application->MainForm->Handle, NM_STORESCP_CALLBACK,
          (WPARAM)progress, (LPARAM)filename);
}
void __fastcall TfrmMain::OnStoreSCPCallback(TMessage &Message)
{
    ///response to the message ,do something accoring to WPARAM LPARAM
}
void __fastcall TfrmMain::FormShow(TObject *Sender)
{
   //now callback here 
   storescp_execute(m_iServerPort, MyStoreScpCallback);    
}

/////////////cfrmmain.h///////
enum { NM_STORESCP_CALLBACK = WM_USER + 100 }; 
void __stdcall MyStoreScpCallback(T_StoreProgress* progress, LPCSTR filename);
class TfrmMain : public TForm
{
  BEGIN_MESSAGE_MAP
        VCL_MESSAGE_HANDLER(NM_STORESCP_CALLBACK, TMessage,  OnStoreSCPCallback);
    END_MESSAGE_MAP(TForm);
}

void __stdcall MyStoreScpCallback(T_StoreProgress* progress, LPCSTR filename)
{
    ///emit the message user defined :in QT ,how to postEvent and get the receive ????
    SendMessage(Application->MainForm->Handle, NM_STORESCP_CALLBACK,
          (WPARAM)progress, (LPARAM)filename);
}
