关于Qt的QListWidget如何调节列表项高度的问题

各位大神好，最近在学Qt做界面，想要实现一个稍微复杂一点的列表框，网上查资料也实现了这个功能，但是效果不尽如人意。我的代码如下



        QListWidgetItem* Item = new QListWidgetItem(m_pCaseListView);

        QWidget *pContainer = new QWidget(m_pCaseListView);

        QHBoxLayout *hLayout = new QHBoxLayout(pContainer);

        QHBoxLayout *hLeftLayout = new QHBoxLayout(pContainer);

        QHBoxLayout *hRightLeftLayout = new QHBoxLayout(pContainer);

        QHBoxLayout *hRightRightLayout = new QHBoxLayout(pContainer);

        QHBoxLayout *hRightLayout = new QHBoxLayout(pContainer);



        QLabel *pCaseName = new QLabel(*iter);



        QProgressBar *pProBar = new QProgressBar(pContainer);

        pProBar->setRange(0, 1000);                             //当前只为了看效果，数字无实际意义

        pProBar->setValue(100);                                 //当前只为了看效果，数字无实际意义



        //添加三个按钮，实现运行、停止运行、删除功能

        QPushButton *pRunButton = new QPushButton(pContainer);

        pRunButton->setStyleSheet("QPushButton{border-image:url(:/images/images/runbutton.png)}");

        QPushButton *pStopButton = new QPushButton(pContainer);

        pStopButton->setStyleSheet("QPushButton{border-image:url(:/images/images/stopbutton.png)}");

        QPushButton *pDelButton = new QPushButton(pContainer);

        pDelButton->setStyleSheet("QPushButton{border-image:url(:/images/images/delbutton.png)}");



        //将各个空间添加到水平布局器中

        hLeftLayout->addWidget(pCaseName);

        hRightLeftLayout->addWidget(pProBar);

        hRightRightLayout->addStretch(1);

        hRightRightLayout->addWidget(pRunButton);

        hRightRightLayout->addStretch(1);

        hRightRightLayout->addWidget(pStopButton);

        hRightRightLayout->addStretch(1);

        hRightRightLayout->addWidget(pDelButton);

        hRightRightLayout->addStretch(1);



        //设置布局器的比例

        hRightLayout->addLayout(hRightLeftLayout);

        hRightLayout->addLayout(hRightRightLayout);

        hRightLayout->setStretchFactor(hRightLeftLayout, 1);

        hRightLayout->setStretchFactor(hRightRightLayout, 1);

        hLayout->addLayout(hLeftLayout);

        hLayout->addLayout(hRightLayout);

        hLayout->setStretchFactor(hLeftLayout, 1);

        hLayout->setStretchFactor(hRightLayout, 1);

        hLayout->setContentsMargins(5,2,5,2);

        pContainer->setLayout(hLayout);



        m_pCaseListView->setItemWidget(Item, pContainer);

外层有一个for循环，设置QLabel显示的内容QLabel *pCaseName = new QLabel(*iter);
代码运行结果如下

我想请教各位两个问题：
1：QLabel文字内容长的话控件的对齐会出现问题，这个问题要怎么解决呢？
2：如何调节列表项的高度，大家也看到了按钮的图片被压缩的很严重？
