::PostMessage in Qt !

[Velab]

Hello,

I have to convert C++ win32 API to , Qt DLL.

In doing this, i struked in using **::PostMessage ** funictionality in Qt.
::PostMessage(m_hwndDest,m_nQuaternionMsg,MAKEWPARAM(marg,eErrors),LPARAM(m_lParam));

Could anyone please let me know,
How can i use, ::PostMessage funtionality in Qt ?

@Velab You have a few options here, the first one is using QCoreApplication::postEvent, it will simulate the PostMessage.

The other solution is to use QTimer::singleShot, you can use with the msec as 0, which you would have the same functionality.

And one similar to QTimer but passing arguments, you could use QMetaObject::invokeMethod with Qt::QueuedConnection as type parameter.

Qt::DirectConnection would execute the method immediately, whilst Qt::QueuedConnection would queue in the event loop.
