Question

不确定这是一个错误，还是意图。谷歌搜索这个除了标题为QT-Creator Troubleshoot之外没有提供任何信息：

指针变量成员不会直接显示

简单地参考：启用指针解除指示。

我已启用此功能，请参阅调试会话的屏幕截图

问题：

就像创建一个新对象一样，例如：

QString newString = QString("This is a new string");

显示在调试器中，newString的内容显示在调试器中。

然而将其更改为指针，例如

QString *newString = new QString("This is a new string");

正如屏幕截图中所有已定义的指针一样，这些指针和newString指针将无法解析所持有的内容。

这是一个错误还是QT无法解决此问题？

请参阅下面的调试器信息的深入视图：
