[since 5.5] Qt::MouseEventSource QWheelEvent::source() const
This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.
in 6.0: use pointingDevice()
Returns information about the wheel event source.
The source can be used to distinguish between events that come from a mouse with a physical wheel and events that are generated by some other means, such as a flick gesture on a touchpad. This enum tells you from where it was synthesized; but often it's more useful to know from which device it was synthesized, so try to use pointingDevice() instead.
Note: Many platforms provide no such information. On such platforms Qt::MouseEventNotSynthesized is returned always.
This function was introduced in Qt 5.5.
