问题描述

我正在尝试在带有Qt扩展名的Visual Studio上的 release 模式下运行一个简单的模板.到目前为止，我一直在以调试模式运行项目(从未遇到过麻烦).最近，我从一个使用 webengine 小部件的浏览器应用程序开始，但是在调试模式下它非常慢.在继续之前，我想确保可以以更高的性能(在发布模式下)运行.

I'm trying to run a simple template in release mode on Visual Studio with the Qt extension. So far I've always been running projects in debug mode (never had trouble). Recently, I started with a browser application using webengine its widgets, but it's very slow on debug mode, so. I wanted to make sure it's possible to run with higher performance (on release mode), before continuing.

我很惊讶，因为在尝试运行该应用程序后，该应用程序相互抛出了4条错误消息弹出窗口:

I was surprised, because the application throws 4 error message pop-ups after each other after trying to run it:

因此，我改为尝试编译一个简单的项目(直接的QtWidgetsApplication模板)，它为我提供了这一点:

我已经寻找解决方案已有一段时间了，但是我没有找到明确的答案.

I've been looking for a solution for quite some time now, but I didn't find a clear answer.

我的目录: C:\ Qt \ 5.14.1 \ msvc2017_64

我的模板代码:

#include "QtWidgetsApplication2.h"
#include <QtWidgets/QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QtWidgetsApplication2 w;
    w.show();
    return a.exec();
}

#pragma once

#include <QtWidgets/QMainWindow>
#include "ui_QtWidgetsApplication2.h"

class QtWidgetsApplication2 : public QMainWindow
{
    Q_OBJECT

public:
    QtWidgetsApplication2(QWidget *parent = Q_NULLPTR);

private:
    Ui::QtWidgetsApplication2Class ui;
};

#include "QtWidgetsApplication2.h"

QtWidgetsApplication2::QtWidgetsApplication2(QWidget *parent)
    : QMainWindow(parent)
{
    ui.setupUi(this);
}

我不知道如何解决此问题.你能帮我吗?预先感谢！
