QWheelEvent::QWheelEvent(const QPointF &pos, const QPointF &globalPos, int delta, Qt::MouseButtons buttons, Qt::KeyboardModifiers modifiers, Qt::Orientation orient = Qt::Vertical)

Constructs a wheel event object.

Use the constructor taking angleDelta and pixelDelta QPoints instead.

The pos provides the location of the mouse cursor within the widget. The position in global coordinates is specified by globalPos. delta contains the rotation distance, modifiers holds the keyboard modifier flags at the time of the event, and orient holds the wheel's orientation.

参见 pos(), pixelDelta(), and angleDelta().

QWheelEvent::QWheelEvent(const QPointF &pos, int delta, Qt::MouseButtons buttons, Qt::KeyboardModifiers modifiers, Qt::Orientation orient = Qt::Vertical)

Constructs a wheel event object.

Use the constructor taking angleDelta and pixelDelta QPoints instead.

The position, pos, is the location of the mouse cursor within the widget. The globalPos() is initialized to QCursor::pos() which is usually, but not always, correct. Use the other constructor if you need to specify the global position explicitly.

The buttons describe the state of the mouse buttons at the time of the event, delta contains the rotation distance, modifiers holds the keyboard modifier flags at the time of the event, and orient holds the wheel's orientation.

参见 pos(), pixelDelta(), and angleDelta().

int QWheelEvent::delta() const

This function has been deprecated, use pixelDelta() or angleDelta() instead.

Qt::Orientation QWheelEvent::orientation() const

Returns the wheel's orientation.

Use angleDelta() instead.
