QListWidget加入小控件

void QListWidget::setItemWidget(QListWidgetItem * item, QWidget * widget)

关键代码：

//图片换成目录图标就能够

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

{

    QApplication  app(argc,argv);

    QListWidget  *listWidget = new QListWidget();

    listWidget->setSpacing(10);

    listWidget->setViewMode(QListView::IconMode);

    listWidget->setIconSize(QSize(100,100));

    QPixmap pix1(QString(":/list/image/1.jpg"));

    QPixmap pix2(":/list/image/2.jpg");

    QListWidgetItem *item1 = new QListWidgetItem(QIcon(pix1.scaled(QSize(100,100))),"picture1");

    QListWidgetItem *item2 = new QListWidgetItem(QIcon(pix2.scaled(QSize(100,100))),"picture2");

    QLineEdit*   line = new QLineEdit; //创建部件

    listWidget->addItem(item1);

    listWidget->addItem(item2);  //先加入项目

    item1->setSizeHint(QSize(100,120));

    item2->setSizeHint(QSize(100,120));

    listWidget->setItemWidget(item2,line); //加入部件

//  listWidget->removeItemWidget(item2);

    listWidget->show();

    app.exec();

    return 0;

}
