Member Function Documentation
[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).
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.
