篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Visual Studio Code开发Qt应用程序实现自动提示语法高亮代码导航编译和调试相关的知识，希望对你有一定的参考价值。

准备开发软件

以下简称Visual Studio Code为VSCode。

前言

Visual Studio在安装Qt插件后虽然能进行Qt应用开发，但是它本身的体积太大，微软还没有开放Visual Studio单独安装C++开发包的方法。Qt Creator 大版本号仍然停留在4.3上，某些功能迟迟等不来更新和实现，特别是——调试功能。在非用户代码中出现的ASSERT错误，QT Creator不告诉用户代码堆栈，只显示第三方代码哪里ASSERT，让人无语。虽然UI开发、SIGNAL-SLOT的设计仍然由Qt Creator借力，但其它开发工作在VS Code上进行会更让用户省心省力。本文将重点介绍如何用VS Code开发Qt5应用程序。

VSCode本身没有针对Qt应用开发的插件程序，开发工作进行之前务必确保C++开发功能正常。关于VSCode C++开发环境的配置请参考：《VSCode实现C++代码提示、语法高亮、编译和调试》

开发环境

Windows Software Development Kit 10.0.15063
- Windows SDK的下载地址是：https://developer.microsoft.com/zh-cn/windows/downloads/windows-10-sdk。
Microsoft Visual C++ Build Tools 2015
- Microsoft Visual C++ Build Tools 2015 的下载地址是：http://landinghub.visualstudio.com/visual-cpp-build-tools，此安装包含Windows SDK 8.1和 Windows SDK 10.0.10240，因版本过时，不建议安装。
Microsoft Visual Studio Code
- Microsoft Visual Studio Code的下载地址是：https://code.visualstudio.com/?wt.mc_id=DX_841432。
Qt 5.9.1 for Windows
- Qt 5.9.1 for Windows的下载地址是：https://www1.qt.io/download-open-source/?hsCtaTracking=f977210e-de67-475f-a32b-65cec207fd03%7Cd62710cd-e1db-46aa-8d4d-2f1c1ffdacea#section-2。此下载链接要求用户已经登录到Qt网站。如果需要PDB符号，请下载源代码并自行编译。
Cppcheck 1.8
- Cppcheck 1.8的下载地址是：http://cppcheck.sourceforge.net/。这个工具对于C++代码检查、代码提示非常有帮助。安装过程结束后把工具的安装位置加入Path环境变量。
LLVM 5.0
- LLVM 5.0的下载地址是：http://releases.llvm.org/download.html。LLVM自带的CLang工具对代码自动格式化非常有帮助。此外LLVM也是一款很好用的编译套件，以后也用的上。安装过程结束后把工具的安装位置加入Path环境变量。
CMake 3.9
- CMake 3.9的下载地址是：https://cmake.org/download/。CMake是一套自动编译工具，它提供可视化的图形界面，自动生成适用于各种编译平台的Makefile。VS Code的C++编译套件对它有依赖。虽然下文用的是NMake，但CMake留着也不错。安装过程结束后把工具的安装位置加入Path环境变量。

安装顺序按照以上列出软件的顺序进行。

Demo

VSCode开发Qt应用程序比开发单纯的C++程序更简单，因为Qt会自己生成Makefile，免去了用户编译Makefile的烦恼。

命令提示符

Qt所有的平台都有一个类似于Visual Studio中vcvars.bat这样的批处理文件，叫做qtenv2.bat。它的作用是把当前平台的bin目录加入到应用程序的Path环境变量。打开一个简单的Qt编译命令窗口的代码很简单，代码如下：

@echo off
title qmake and nmake build prompt
set VCINSTALLDIR=C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC
set QTDIR=C:\\Qt\\Qt5.9.1\\5.9.1\\msvc2015_64
set PATH=%VCINSTALLDIR%\\bin;%QTDIR%\\bin;C:\\Program Files\\7-Zip;%PATH%
call "%VCINSTALLDIR%\\vcvarsall.bat" amd64
cmd /k

新建工程

模板选择是Qt Widgets Application，如下图所示：

输入工程名称demo1，如下图所示：

Kit Selection去掉其它所有的选择，只留下MSVC2015 X64，如下图所示：

不用输入什么，进入下一步，如下图所示：

暂不启用版本控制，如下图所示：

创建成功。如下图所示：

用VSCode打开工程文件夹，如下图所示：

自动提示与代码导航

在.vscode文件夹下新建c_cpp_properties.json，代码如下：

以上配置成功后自动提示、语法高亮、代码导航等功能可以正常工作。

编译

修改默认的编译任务，即tasks.json，代码如下：


    "version": "2.0.0",
    "tasks": [
        "taskName": "demo1 Debug",
        "type": "shell",
        "command": "cmd",
        "args": [
            "/c",
            "$workspaceRoot/build.cmd",
            "debug"
        ],
        "group": 
            "kind": "build",
            "isDefault": true
        
    ]

新建build.cmd，代码如下：

@echo off
title qmake and nmake build prompt
set VCINSTALLDIR=C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC
set QTDIR=C:\\Qt\\Qt5.9.1\\5.9.1\\msvc2015_64
set PATH=%VCINSTALLDIR%\\bin;%QTDIR%\\bin;C:\\Program Files\\7-Zip;%PATH%
call "%VCINSTALLDIR%\\vcvarsall.bat" amd64
qmake demo1.pro -spec win32-msvc "CONFIG+=debug" "CONFIG+=qml_debug"
nmake
cd debug
windeployqt demo1.exe

调试

新建launch.json，代码如下：


    "version": "0.2.0",
    "configurations": [
        "name": "CDB",
        "type": "cppvsdbg",
        "request": "launch",
        "program": "demo1.exe",
        "args": [],
        "stopAtEntry": false,
        "cwd": "$workspaceRoot/debug/",
        "environment": [],
        "externalConsole": true
    ]

试试效果

VSCode调试功能强于Qt，Qt UI设计功能又强于VSCode，两者互补，给我们工作带来不少方便。以上配置完成后就可以尝到C++与Qt联合工作的甜头了。

编译效果

按下Ctrl+Shilt+B试试，截图如下：

调试效果

写两个局部变量看看：

    int a=1;
    int b=2;
    int c=a+b;
    qDebug()<<a<<"+"<<b<<"="<<c;

先下一个断点，如下图所示：

按下F5，如下图所示：

代码导航效果

代码编辑器已经能够导航了，如下图所示：

至此，Visual Studio Code开发Qt应用程序实现自动提示、语法高亮、代码导航、编译和调试工作全部成功完成。
