在桌面应用、嵌入式系统等开发领域中，C++与Qt6的组合一直是开发者的优选方案之一。二者结合不仅能发挥C++的性能优势，还能借助Qt6的框架能力大幅度提升开发效率，尤其在跨平台场景下优势显著。

一、准备开发环境

开发工具：Visual Studio 2022

开发环境：Qt6.9

二、创建新项目

1.在Visual Studio中创建新项目，选择Qt Widgets Application

2.输入项目名后点击创建

3.弹出Qt的引导界面，点击下一步，选择开发版本以及所需的库，默认的Qt Core,QtGui,QtWidgets即可完成项目创建

三、设计用户界面

MacOS桌面应用窗口的显著特征是整体窗口为圆角，顶部标签栏为毛玻璃且窗口名在标签栏中心位置，关闭、最小化、缩放按钮则在标签栏的最左侧，且为红黄绿三种颜色。

四、编写代码

创建两个文件：macwindow.cpp,macwindow.h

macwindow.h

#pragma once
#include <QMainWindow>
#include <QWidget>
#include <QGraphicsEffect>class MacWindow : public QMainWindow
{Q_OBJECT
public:explicit MacWindow(QWidget *parent = nullptr);protected:void paintEvent(QPaintEvent *event) override;void mousePressEvent(QMouseEvent *event) override;void mouseMoveEvent(QMouseEvent *event) override;private:QPoint m_dragPosition;
};

macwindow.cpp

}void MacWindow::paintEvent(QPaintEvent *event) {Q_UNUSED(event);QPainter painter(this);painter.setRenderHint(QPainter::Antialiasing);painter.setPen(Qt::NoPen);painter.setBrush(QColor(240, 240, 240));painter.drawRoundedRect(rect(), 6, 6);
}void MacWindow::mousePressEvent(QMouseEvent *event) {if (event->button() == Qt::LeftButton) {m_dragPosition = event->globalPosition().toPoint() - this->frameGeometry().topLeft();event->accept();}
