code to populate it

    filemanager FileManager;

    QStringList test = FileManager.openDir(":/image/palettes/");
    int cc=0;
    for (QString &s : test)
    {
        QPushButton *button = new QPushButton;
        button->setObjectName("DeviceButton" + QString::number(cc++));
        button->setMinimumHeight(45);
        button->setMaximumHeight(45);
        button->setCursor(Qt::PointingHandCursor);

        button->setStyleSheet("border-image: url("+s+") 0 0 0 0 stretch stretch;");
        connect(button, &QPushButton::clicked, [=]() { sendBinary("paletteActive", cc); });
        ui->gridLayoutPaletteContent->addWidget(button);
    }

when running this on my android tablet i can't scroll by just touching, hold and drag on the screen, i have to do it on the scrollbar to the right!

how do i fix this?
