Confusion about events posted from slots

[elizabeth.h1]

Hello

If I have the following code

void someslotFunc()
{
    qApp->postEvent(QEvent::SomeEventType);
}

void someslotFunc()
{
    qApp->postEvent(QEvent::SomeEventType);
}

To copy to clipboard, switch view to plain text mode 

When the posted event will be processed ? When control gets to the main loop, right? Or it will be processed inside the slot?
Think that the case is when control gets to the main loop, but I am not sure
Thanks
