Qt 是一款跨平台的 C++ 应用程序开发框架,具有强大的功能和丰富的工具集。我最早接触Qt的时候还是4.3版本了,如今的Qt已经发展到6.x版本了,Qt 6 也引入了新的图形系统,支持 Vulkan 作为后端,为开发高性能图形应用提供了强大支持。
目前,由于网络限制等原因,在安装下载Qt时,建议使用国内镜像加速下载过程,以提高安装效率,Qt官网也提供了镜像资源列表,鼓励使用镜像下载。
国内常用的镜像推荐:
腾 讯 镜 像 :https://mirrors.cloud.tencent.com/qt/
阿里云镜像:https://mirrors.aliyun.com/qt/
安装Qt
- 下载Qt在线安装工具
访问 Qt 官方网站 https://www.qt.io/download-open-source 下载 Qt Online Installer。
- 打开命令提示符窗口(CMD),运行以下命令(以Qt Online Installer 4.6.0版本和阿里云镜像为例)
qt-unified-windows-x64-4.6.0-online.exe --mirror https://mirrors.aliyun.com/qt/
更新Qt
- 打开命令提示符窗口(CMD),使用维护工具MaintenanceTool.exe运行以下命令(以阿里云镜像为例):
MaintenanceTool.exe --mirror https://mirrors.aliyun.com/qt/
