向QListWidgetItem中添加自定义的部件时，莫忘记设置其尺寸提示sizeHint，否则部件可能显示不出来或者显示得不正确。

亮点：

#include <QtGui>

int main(int argc, char *argv[])

{

QApplication a(argc, argv);

QListWidget list;

for (int i = 0; i < 10; ++i) {

QIcon icon = QIcon::fromTheme("edit-undo");

QListWidgetItem *item = new QListWidgetItem();

item->setIcon(icon);

list.addItem(item);

QPushButton *button = new QPushButton("Button");

QLabel *label = new QLabel("Text");

QHBoxLayout *layout= new QHBoxLayout();

layout->addWidget(label);

layout->addWidget(button);

QWidget *widget = new QWidget();

widget->setLayout(layout);

item->setSizeHint(widget->sizeHint());

list.setItemWidget(item, widget);

}
