示例1: mousePressEvent
void ItemScene::mousePressEvent(QGraphicsSceneMouseEvent *event)
{
if(this->sceneType == MenuDisplay)
{
cout << "Width: " << this->sceneRect().width() << endl;
QList<QGraphicsView*> parentViews = this->views();
cout << parentViews.size() << endl;
MainMenu* view = (MainMenu*)parentViews.at(0);
int viewPosX, viewPosY, viewWidth, viewHeight, imagePosX, imagePosY, imageWidth, imageHeight;
viewPosX = view->getPosition()->x();
viewPosY = view->getPosition()->y();
viewWidth = view->width();
viewHeight = view->height();
imagePosX = this->imageDisplay->imageFileItem->pos().x();
imagePosY = this->imageDisplay->imageFileItem->pos().y();
imageWidth = this->imageDisplay->imageFileItem->boundingRect().width();
imageHeight = this->imageDisplay->imageFileItem->boundingRect().height();
if( (viewPosX + viewWidth >= imagePosX || viewPosX + viewWidth >= imagePosX + imageWidth ) &&
(viewPosY <= imagePosY || viewPosY <= imagePosY + imageHeight) )
{
QPointF position(viewPosX + event->scenePos().x(), viewPosY + event->scenePos().y());
this->imageDisplay->addSelectionMarker(position);
}
}
update();
QGraphicsScene::mousePressEvent(event);
}示例2: main
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainMenu w;
QRect screenGeometry = QApplication::desktop()->screenGeometry();
int x = (screenGeometry.width()-w.width()) / 2;
int y = (screenGeometry.height()-w.height()) / 2;
w.move(x, y);
w.show();
return a.exec();
