qt creator太难用了，转到vscode开发qt。

新建项目

命令行编译

ok，这是一个完整的流程，接下来用命令行实现 主要用到三个命令：qmake.exe，mingw32-make.exe，gcc.exe
qmake作用是解析xx.pro文件，生成跨平台编译的的makefile文件；
mingw32-make是make命令的windows实现，作用是调用工具链，编译成平台可执行文件，比如exe
gcc，顾名思义，编译器，把代码编译成二进制码

vscode编译

vscode需要用到两个配置：c++、外部指令(qmake、mingw32-make算是外部指令)
安装c++插件，设置智能补全
项目根目录下创建这两个文件，一个是c++编译相关配置，task.json是调用外部指令的配置
配置完成后 ： ctrl+shift+p–>run task–>run-debug

注意点

1 windows下不要在类linux系统执行，code打开项目，会出现路径解析错误
2 QML文件好好写，弹窗出不来，找了半天原因，发现qml写的不对
