[explicit] QWheelEvent::QWheelEvent(const ::QWheelEvent &e)▲

Constructs a new QWheelEvent instance from the QWheelEvent e.

QPoint QWheelEvent::angleDelta() const▲

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).

Getter function for property angleDelta.

int QWheelEvent::buttons() const▲

Returns a bitfield to be used to check for mouse buttons that may be accompanying the wheel event.

Getter function for property buttons.

bool QWheelEvent::isAccepted() const▲

Returns whether the event was accepted.

Getter function for property accepted.

Qt3DInput::QWheelEvent::Modifiers QWheelEvent::modifiers() const▲

Returns the keyboard modifiers that may be accompanying the wheel event.

Getter function for property modifiers.

void QWheelEvent::setAccepted(bool accepted)▲

Sets the event as accepted if accepted is true.

When an event is accepted, it will prevent further propagation to other listeners.

Setter function for property accepted.
