How to wait a thread completion without blocking the gui?

[Baldassarre Cesarano]

Following the documentation, I wrote a class derived from wxThread =

passing a wxCondition and expect the completion with condition.Wait () =

 =

I tried all combinations wxTHREAD_JOINABLE/wxTHREAD_DETACHED =

and entering in the body of thread =

wxYield and/or wxThread:Sleep!!!!!
 =

However, the user interface remains blocked
 =

How can I fix this?

PS. This is the sample code
-----------------------------------------------
class Test_SignallingThread : public wxThread {
public:
 Test_SignallingThread( wxMutex  *mutex,
       wxCondition *condition,
       long  msTimeout
      )
//  : wxThread( wxTHREAD_JOINABLE )
//  : wxThread( wxTHREAD_DETACHED )
 {
   m_mutex   =3D mutex;
   m_condition  =3D condition;
   m_msTimeout  =3D msTimeout;
   Create();
  }
 virtual ExitCode Entry();
private:
 wxMutex*  m_mutex;
 wxCondition* m_condition;
 long   m_msTimeout;
};
 =

wxThread::ExitCode Test_SignallingThread::Entry() {
 wxStopWatch msElapsed;
 msElapsed.Start(0);
 while(  ( msElapsed.Time() <=3D m_msTimeout ) //TimeOut
  ){
  // Do some jobs
  //.........
//  wxYield();
//  wxThread::Sleep(80);
 }
 msElapsed.Pause();
 =

 wxMutexLocker lock( *m_mutex );
 m_condition->Broadcast();
 return NULL;
}
 =

.....................
.....(from a  men=F9 event)
void MyFrame::OnTest(wxCommandEvent& WXUNUSED(event)) {
  wxMutex  mutex;
  wxCondition condition( mutex );
  mutex.Lock();
 =

  Test_SignallingThread* thread =3D new Test_SignallingThread( &mutex,
&condition, 10000 );
  if ( thread->Run() !=3D wxTHREAD_NO_ERROR ) {
   wxLogError(wxT("Can't start thread!"));
  }
  condition.Wait();
}
