Scroll gesture difficulties.

[GrishaE]

Hello! I have an issue with scrolling implementation. I`ve made this for Android device.

1. Scrolling a bit sticking, and it doesn't work softly. 2. I`ve notice a big memory consumption. Help.

QScrollArea* sa = new QScrollArea;                                       // Scroll pattern takes begin here
    sa->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    sa->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    QPixmap img2(":/description.jpg");
    auto wgt = new QWidget;
    QPalette pal;
    pal.setBrush(wgt->backgroundRole(), QBrush(img2));
    wgt->setPalette(pal);
 
    wgt->setAutoFillBackground(true);
    wgt->setFixedSize(img2.width(), img2.height());
    QScroller::grabGesture(sa->viewport(), QScroller::LeftMouseButtonGesture);
    sa->setWidgetResizable(true);
    sa->verticalScrollBar()->setSingleStep(1);
    sa->setWidget(wgt);
 
 
 
    //sa->setStyleSheet("QScrollArea {image: url(:/empty.png);}");
 
 
 
    tab->addTab(sa, QPixmap(":/Акаунт.png"), NULL);     // Передаем скролл на вторую вкладку
