The QGraphicsSceneMouseEvent class provides mouse events in the graphics view system.
When a QGraphicsView receives a QMouseEvent, it translates it to a QGraphicsSceneMouseEvent. The event is then forwarded to the QGraphicsScene associated with the view. If the event is not handled by the scene, the view may use it, e.g., for the DragMode.
In addition to containing the item, scene, and screen coordinates of the event (as pos(), scenePos(), and screenPos()), mouse events also contain the coordinates of the previous mouse event received by the view. These can be retrieved with lastPos(), lastScreenPos(), and lastScenePos().
QGraphicsSceneMouseEvent::~QGraphicsSceneMouseEvent | ( | ) |
Destroys the event.
Qt::MouseButton QGraphicsSceneMouseEvent::button | ( | ) | const |
Returns the mouse button (if any) that caused the event.
QPointF QGraphicsSceneMouseEvent::buttonDownPos | ( | Qt::MouseButton | button | ) | const |
Returns the mouse cursor position in item coordinates where the specified button was clicked.
QPointF QGraphicsSceneMouseEvent::buttonDownScenePos | ( | Qt::MouseButton | button | ) | const |
Returns the mouse cursor position in scene coordinates where the specified button was clicked.
QPoint QGraphicsSceneMouseEvent::buttonDownScreenPos | ( | Qt::MouseButton | button | ) | const |
Returns the mouse cursor position in screen coordinates where the specified button was clicked.
Qt::MouseButtons QGraphicsSceneMouseEvent::buttons | ( | ) | const |
Returns the combination of mouse buttons that were pressed at the time the event was sent.
Qt::MouseEventFlags QGraphicsSceneMouseEvent::flags | ( | ) | const |
Returns the mouse event flags. The mouse event flags provide additional information about a mouse event.
QPointF QGraphicsSceneMouseEvent::lastPos | ( | ) | const |
Returns the last recorded mouse cursor position in item coordinates.
QPointF QGraphicsSceneMouseEvent::lastScenePos | ( | ) | const |
Returns the last recorded mouse cursor position in scene coordinates. The last recorded position is the position of the previous mouse event received by the view that created the event.
QPoint QGraphicsSceneMouseEvent::lastScreenPos | ( | ) | const |
Returns the last recorded mouse cursor position in screen coordinates. The last recorded position is the position of the previous mouse event received by the view that created the event.
Qt::KeyboardModifiers QGraphicsSceneMouseEvent::modifiers | ( | ) | const |
QPointF QGraphicsSceneMouseEvent::pos | ( | ) | const |
Returns the mouse cursor position in item coordinates.
QPointF QGraphicsSceneMouseEvent::scenePos | ( | ) | const |
Returns the mouse cursor position in scene coordinates.
QPoint QGraphicsSceneMouseEvent::screenPos | ( | ) | const |
Returns the mouse cursor position in screen coordinates.
Qt::MouseEventSource QGraphicsSceneMouseEvent::source | ( | ) | const |
Returns information about the mouse event source.
The mouse event source can be used to distinguish between genuine and artificial mouse events. The latter are events that are synthesized from touch events by the operating system or CopperSpice itself.
