使用最基本的QListWidgetItem來創建列表項，

具體使用下面setText、setIcon、addItem這三個方法

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include "QDebug"enum CustomRoles {IdRole = Qt::UserRole,      // 存儲IDPhoneRole,                  // 等價于Qt::UserRole+1，存儲電話EmailRole                   // 等價于Qt::UserRole+2，存儲郵箱
};MainWindow::MainWindow(QWidget *parent): QMainWindow(parent), ui(new Ui::MainWindow)
{ui->setupUi(this);for (int i=0;i<15;i++){QListWidgetItem* item=new QListWidgetItem;QIcon b(":/xu/hai/picc/1.jpg");item->setText("dddd");item->setIcon(b);//若所有Item都要存儲一個叫“PhoneRole”字段用于保存電話，一個叫 “EmailRole”字段用于保存郵箱；//不同類型的附加數據需要用不同角色區分item->setData(PhoneRole,i);item->setData(EmailRole,QString("address :%1").arg(i));ui->listWidget->addItem(item);}connect(ui->listWidget, &QListWidget::itemClicked, this, &MainWindow::onListWidgetItemClicked);ui->listWidget->setStyleSheet("QListWidget::item { height: 100px; }");}void MainWindow::onListWidgetItemClicked(QListWidgetItem *item){// 1. 獲取item的文本（setText設置的內容）QString itemText = item->text();qDebug() << "item文本：" << itemText; // 輸出："dddd"// 2. 獲取自定義數據（setData設置的內容）qDebug() <<item->data(PhoneRole).toString() << item->data(EmailRole).toString();
}
MainWindow::~MainWindow()
{delete ui;
}

自定義個一個widget，然后綁定到qListWidgetItem上

formitem.cpp

#include "formitem.h"
#include "ui_formitem.h"
#include <QListWidget>
#include <QListWidgetItem>
#include "formitem.h"
#include <QDebug>
#include <QString>FormItem::FormItem(QWidget *parent) :QWidget(parent),ui(new Ui::FormItem)
{ui->setupUi(this);connect(ui->pushButton,&QPushButton::clicked,[=](){qDebug()<<"FormItem neibu  :"<<"";emit deleteInvok();});
}FormItem::~FormItem()
{delete ui;
}void FormItem::rec(globalVar* itemData){ui->label->setText(itemData->name);ui->label_2->setText(QString::number(itemData->age));ui->label_3->setText(QString::number(itemData->phone));
}

globalvar.h

#ifndef GLOBALVAR_H
#define GLOBALVAR_H#include <QObject>class globalVar : public QObject
{Q_OBJECT
public:explicit globalVar(QObject *parent = nullptr,QString namee="",int agee=0,int phonee=0);QString name;int age;int phone;
};#endif // GLOBALVAR_H

globalvar.cpp

#include "globalvar.h"globalVar::globalVar(QObject *parent,QString namee,int agee,int phonee) : QObject(parent)
{name=namee;age=agee;phone=phonee;
}

{delete ui;
