非阻塞延时

qt 中非阻塞延时方法. void MainWindow::delay(int mSec) { QEventLoop loop; QTimer::singleShot(mSec, &loop, SLOT(quit())); loop.exec(); }  

window c++ 中 非阻塞延时方式

struct XSleep_Structure

{

int duration;

HANDLE evenHandle;

};

// 非阻塞延时

void XSleep(int nWaitInMsecs)

{

XSleep_Structure sleep;

sleep.duration = nWaitInMsecs;

sleep.evenHandle = CreateEvent(NULL,TRUE,FALSE,NULL);

 

DWORD dwThreadId;

CreateThread(NULL,0,&XSleepThread,&sleep,0,&dwThreadId);

  

MSG msg;

while(::WaitForSingleObject(sleep.evenHandle,0) == WAIT_TIMEOUT)

{

// get and dispatch message

if(::PeekMessage(&msg,NULL,0,0,PM_REMOVE))

{

::TranslateMessage(&msg);

::DispatchMessage(&msg);

}

}

CloseHandle(sleep.evenHandle);

}

  

DWORD WINAPI XSleepThread(LPVOID pWaitTime)

{

XSleep_Structure *sleep = (XSleep_Structure*)pWaitTime;

  

Sleep(sleep->duration);

SetEvent(sleep->evenHandle);

  

return 0;

}
