**
问题描：**
在vs2015中，使用了QString变量，但是调试时鼠标放上去只能看到地址，而不是像int变量一样看到具体的值。导致想要看到变量的值只能qDebug()，就很麻烦。
**
**
1.调试-选项-本地兼容模式取消选择（我就是去掉这个然后重开，就可以看到值了）
2.在C:VS2015Common7PackagesDebuggerVisualizers中添加qt5.natvis文件
3.在C:VS2015Common7PackagesDebugger中找到autoexp.dat
找到[Visualizer]并添加
;Qt4
QString{
preview ([$e.d->data,su])
stringview ([$e.d->data,sub])
children
(
#(
d: $c.d,
[size]: $c.d->size,
[referenced]: $c.d->ref._q_value
)
)
}
;Qt5
QString|*::QString{
preview ([(unsigned short*)$e.d + $e.d->offset/2,su])
stringview ([(unsigned short*)$e.d + $e.d->offset/2,sub])
children
(
#(
d: $c.d,
[size]: $c.d->size,
[referenced]: $c.d->ref.atomic._q_value
)
)
}
我是通过第一种方法解决的，后面两种方法我试过但是没效果，另外也可能是安装了vs其它版本的问题，也有人通过重装vs解决了。额，都不行的话，那就qDebug吧。。。
