东西不能知道拿来用,但可以借鉴效果

简单版

    QListWidget *list=new QListWidget;
    QListWidgetItem *item=new QListWidgetItem(list,0); 
    
    item->setSizeHint(QSize(100,100));
    QWidget *w = new QWidget(list);
    QHBoxLayout *layout=new QHBoxLayout(w);
    QPushButton *pushButton=new QPushButton(w);
    QCheckBox *checkBox=new QCheckBox(w);
    layout->addWidget(checkBox);
    layout->addWidget(pushButton);
    w->setLayout(layout);
    w->show();
    list->setItemWidget(item,w);
    list->show();
