Qt工作笔记-QListWidget鼠标拖动，一个到另一个，并遍历

运行截图如下：

源代码很简单，如下：

widget.h

#ifndef WIDGET_H

#define WIDGET_H

#include <QWidget>

#include <QMessageBox>

namespace Ui {

class Widget;

}

class Widget : public QWidget

{

    Q_OBJECT

public:

    explicit Widget(QWidget *parent = 0);

    ~Widget();

public slots:

    void clickedBtn();

private:

    Ui::Widget *ui;

};

#endif // WIDGET_H

main.cpp

#include "widget.h"

#include <QApplication>

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

{

    QApplication a(argc, argv);

    Widget w;

    w.show();

    return a.exec();

}

widget.cpp

#include "widget.h"

#include "ui_widget.h"

Widget::Widget(QWidget *parent) :

    QWidget(parent),

    ui(new Ui::Widget)

{

    ui->setupUi(this);

    QStringList strList={"球球","蘑菇头","闰土","妹爷","腿腿"};

    ui->listWidget->addItems(strList);

    //ui->listWidget->setViewMode(QListView::ListMode);

    ui->listWidget->setDragEnabled(true);

    ui->listWidget_2->setAcceptDrops(true);

    //ui->listWidget_2->setViewMode(QListView::ListMode);

    //ui->listWidget_2->setDragEnabled(true);

    connect(ui->pushButton,SIGNAL(clicked(bool)),this,SLOT(clickedBtn()));

}

void Widget::clickedBtn(){

    QString msg;

    for(int i=0;i<ui->listWidget_2->count();i++){

        msg.append("第"+QString::number(i+1)+"行的数据为："+ui->listWidget_2->item(i)->text()+"\n");

    }

    QMessageBox::information(this,tr("提示"),msg);

}

Widget::~Widget()

{

    delete ui;

}
