求助QT打开文件夹的问题

[louisfly]

发现一个问题，不知道该怎么解决，求高人指点。我的代码是这样的：

mainwindow.h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QtWidgets>

QT_BEGIN_NAMESPACE
namespace Ui { class MainWindow; }
QT_END_NAMESPACE

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    MainWindow(QWidget *parent = nullptr);
    ~MainWindow();

private:
    Ui::MainWindow *ui;
    QPushButton *btn;

private slots:
    void openfile();
};
#endif // MAINWINDOW_H

main.cpp

#include "mainwindow.h"

#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    return a.exec();
}

mainwindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QtWidgets>

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    btn = new QPushButton;
    btn->setText("open");
    connect(btn, &QPushButton::clicked, this, &MainWindow::openfile);

    setCentralWidget(btn);

}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::openfile()
{
    QString fileName = QFileDialog::getOpenFileName(this, tr("Open File"),"/home",tr("Images (*.png *.xpm *.jpg)"));

}

我就放了一个button，然后点击之后打开一个文件对话框，获取打开的文件路径。虽然没有报错，但是在点击button的时候，qt输出端会显示以下信息：

请求解决办法，是哪里少设置了什么吗？

[不易易]

亲测代码没问题
可以重新建工程试一遍

[abcowo]

我也出现了这个问题，也是不知道怎么办，就没有大神出现嘛

[芒果黑]

系统问题吧 ShellStreamsFolder::CreateViewObject是win api
