关于QT的一个基础的对象销毁的问题!
DragWidget::DragWidget(QWidget *parent)
: QFrame(parent)
{
setMinimumSize(200, 200);
setFrameStyle(QFrame::Sunken | QFrame::StyledPanel);
setAcceptDrops(true);
QLabel *boatIcon = new QLabel(this);
boatIcon->setPixmap(QPixmap(":/images/boat.png"));
boatIcon->move(10, 10);
boatIcon->show();
boatIcon->setAttribute(Qt::WA_DeleteOnClose);
QLabel *carIcon = new QLabel(this);
carIcon->setPixmap(QPixmap(":/images/car.png"));
carIcon->move(100, 10);
carIcon->show();
carIcon->setAttribute(Qt::WA_DeleteOnClose);
QLabel *houseIcon = new QLabel(this);
houseIcon->setPixmap(QPixmap(":/images/house.png"));
houseIcon->move(10, 80);
houseIcon->show();
houseIcon->setAttribute(Qt::WA_DeleteOnClose);
}
