    Hi,

    https://doc.qt.io/qt-6/qt3dinput-qmousehandler.html#wheel sends a Qt3DInput::QWheelEvent pointer.

    Some documentation of other signals, eg. QNetworkAccessManager::finished state I have to delete(Later) the received passed in pointer.

    Should I also delete (or ...Later?) the pointer passed into the wheel slot? The documentation of the signal doesn't state anything to this regard.

      @uani No, you do not have to delete the events - those are handled by Qt.
