Hi I'd like to do something like this: QTimer::singleShot(5000, this, SLOT(MySlot(iID))); to get the ID (can be 1 to 16) and know which ID did kick off the singleShot. However, that seems not to be possible with on-board tools. Any idea how this can be e... how to pass arguments to QTimer::singleshot slot | Qt Forum No, you cannot.
