Avoiding system signals

[brevleq]

I have a connection in a QSpinBox, but I need differentiate who emitted the signal, user or code, how can I do it??

The signal is valueChanged.

Not really sure why you will need it, but the only way I see is to track of mouse/keyboard events for same SpinBox as well. So if valueChanged() emitted - check for previous mousePressEvent()/KeyboardPressEvent()/keyboardReleaseEvent() for that spinbox in your custom list of events, then clear that list for next iteration.

You can block signals temporarily meanwhile setting the value in code:

spinBox->blockSignals(true);
spinBox->setValue(...);
spinBox->blockSignals(false);

spinBox->blockSignals(true);
spinBox->setValue(...);
spinBox->blockSignals(false);
