示例1: mousePressEvent
void Viewport::mousePressEvent(QMouseEvent * event) {
int x = event->x();
int y = event->y();
Point2D * point = pointInPosition(x,y);
if(event->button() == Qt::LeftButton) { // Clic gauche
// Un point ne peut etre cree que s'il ne se superpose pas a un autre.
// De plus, si des points sont presents dans le viewport, il faut que le point actuellement selectionne soit le premier point de la
// trajectoire ou le dernier.
if(point == NULL && (selectedPoint == &(points.front()) || selectedPoint == &(points.back()) || selectedPoint == NULL)) {
if(selectedPoint == &(points.back())){
addPoint(x,y,END);
this->repaint();
enterTime(&(points.back()));
} else {
addPoint(x,y,BEGIN);
this->repaint();
enterTime(&(points.front()));
}
}
} else if(event->button() == Qt::RightButton) { // Clic droit
