【VS】【Qt】vs+ qt .natvis 失效问题
.natvis文件用于调试时候自定义显示自定义类型的可视化提示。
一般这类文件存在
C:\Program Files (x86)\Microsoft Visual Studio\2022\Enterprise\Common7\Packages\Debugger\Visualizers路径下。
.natvis文件的规则在此不介绍，详见官网：在调试器中创建本机对象的自定义视图
在natvis失效的时候，检查以下选项是否被勾选，如果是，则解除勾选
如果没勾选还是无法显示正确的自定义试图，则考虑是否natvis文件出错。
在此处选择详细，在debug的时候检查需要可视化的自定义类型，直接对日志搜索你的自定义类名如：“QString”。如果出现error，检查error项对应的问题。然后根据error更改对应的natvis文件
最常见的错误
任然报错"##NAMESPACE##::QPoint"无效,
解决方法:删除qt4.natvis内的所有"##NAMESPACE##::"字符,tios调试时可正常显示
qt4 qt5版本比较常见 此处记录一下qt4的。
记录 qt4.natvis
