QLoggingCategory in base class

[beecksche]

Hi,
is it correct to use QLoggingCategory as shown below? It compiles and works, but I have no experience with this.

class BaseClass{
    BaseClass(const char* categoryName = nullptr) : loggingCategory(categoryName ) {}

    void func() { qCDebug(loggingCategory) << "Debug output"; }

private:
    QLoggingCategory loggingCategory;
}

class Class1 : public BaseClass{
    Class1() : BaseClass("my.category1") {}
}

class Class2 : public BaseClass{
    Class2 () : BaseClass("my.category2") {}
}

The reason behind this: I want to detect from which inherited class the debug message was created.
