Member Function Documentation

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).

Note: 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.

Note: Getter function for property buttons.

bool QWheelEvent::isAccepted() const

Returns whether the event was accepted.

Note: Getter function for property accepted.

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

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

Note: Getter function for property modifiers.

void QWheelEvent::setAccepted(bool accepted)

Sets the event as accepted if accepted is true.

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

Note: Setter function for property accepted.

See also isAccepted().

QEvent::Type QWheelEvent::type() const

Returns the QEvent::Type of the event.

int QWheelEvent::x() const

Returns the x position of the mouse event.

Note: Getter function for property x.

int QWheelEvent::y() const

Returns the x position of the mouse event.

Note: Getter function for property y.
