详细描述
The Qt3DCore::QMouseEvent contains parameters that describe a mouse event.
Mouse events occur when a mouse button is pressed and the ray traversing the view, originating from the mouse position intersects with one or more elements of the scene.
参见 QKeyEvent, QWheelEvent, and QMouseHandler.

成员函数
QMouseEvent::QMouseEvent(const QMouseEvent &e)
Constructs a new QMouseEvent instance for the QMouseEvent e.
QMouseEvent::~QMouseEvent()
Destroys the instance of QMouseEvent.
Buttons QMouseEvent::button() const
Returns the mouse button of the mouse event.
Note: Getter function for property button.
int QMouseEvent::buttons() const
Returns a bitfield to be used to check for mouse buttons that may be accompanying the mouse event.
Note: Getter function for property buttons.
bool QMouseEvent::isAccepted() const
Returns whether the event was accepted.
Note: Getter function for property accepted.
Modifiers QMouseEvent::modifiers() const
Returns the keyboard modifiers that may be accompanying the mouse event.
Note: Getter function for property modifiers.
void QMouseEvent::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.
参见 isAccepted().
QEvent::Type QMouseEvent::type() const
Returns the QEvent::Type of the event.
int QMouseEvent::x() const
Returns the x position of the mouse event.
Note: Getter function for property x.
int QMouseEvent::y() const
Returns the y position of the mouse event.
Note: Getter function for property y.
