ui.setupUi(this);
    setFixedSize(800, 600);

    QListWidget* pListWidget = new QListWidget(this);
[color=#ff0000]    pListWidget->setFixedSize(this->size());[/color]
    QListWidgetItem* pItem = new QListWidgetItem(pListWidget);
    pItem->setSizeHint(QSize(800, 200));
    pListWidget->addItem(pItem);
    QWidget* pWidget = new QWidget(this);
    QLabel* pLb = new QLabel(tr("Test"), pWidget);
    QPushButton* pBtn = new QPushButton(tr("test"), pWidget);
    QVBoxLayout* pV = new QVBoxLayout;
    pV->setMargin(0);
    pV->setSpacing(0);
    pV->addWidget(pLb, 0, Qt::AlignCenter);
    pV->addStretch();
    pV->addWidget(pBtn);
    pWidget->setLayout(pV);
    pListWidget->setItemWidget(pItem, pWidget);
    QListWidgetItem* pItem1 = new QListWidgetItem(pListWidget);
