构造新的 QWheelEvent instance from the QWheelEvent e .
Destroys the instance of QWheelEvent.
Returns the distance that the wheel is rotated, in eighths of a degree. A positive value indicates that the wheel was rotated forward (away from the user), a negative value indicates the wheel was rotated backward (toward the user).
注意: Getter 函数对于特性 angleDelta .
Returns a bitfield to be used to check for mouse buttons that may be accompanying the wheel event.
注意: Getter 函数对于特性 buttons .
Returns whether the event was accepted.
注意: Getter 函数对于特性 accepted .
Returns the keyboard modifiers that may be accompanying the wheel event.
注意: Getter 函数对于特性 modifiers .
Sets the event as accepted if accepted 为 true。
注意: When an event is accepted, it will prevent further propagation to other listeners.
注意: Setter 函数对于特性 accepted .

返回 QEvent::Type of the event.
Returns the x position of the mouse event.
注意: Getter 函数对于特性 x .
Returns the x position of the mouse event.
