Member Function Documentation

Q3DWheelEvent::Q3DWheelEvent(const QWheelEvent & e)

Constructs a new Qt3D::Q3DWheelEvent instance from the QWheelEvent e.

Q3DWheelEvent::~Q3DWheelEvent()

QPoint Q3DWheelEvent::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 Q3DWheelEvent::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 Q3DWheelEvent::isAccepted() const

Returns whether the event was accepted.

Note: Getter function for property accepted.

Modifiers Q3DWheelEvent::modifier() const

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

Note: Getter function for property modifier.

void Q3DWheelEvent::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 Q3DWheelEvent::type() const

Returns the QEvent::Type of the event.

int Q3DWheelEvent::x() const

Returns the x position of the mouse event.

Note: Getter function for property x.

int Q3DWheelEvent::y() const

Returns the x position of the mouse event.

Note: Getter function for property y.
