    Howdy, was wondering how you'd assign a newly created class to any existing member? I have this so far:

    classTest.h
    
    private:
            ClassToConstruct classToConstruct;
    
    classTest.cpp
    
    void classTest::myMethod()
    {
            *classToConstruct = new ClassToConstruct(); // this gets added to the classToConstruct class member in classTest.h
    }

        @Christian-Ehrlicher I haven't coded yet, thinking on paper.

          Then take a C++ book and read :)

            @Christian-Ehrlicher That's what I'm doing now actually, got time during a lockdown. Figured I'd ask here first.

                @Calicoder said in Assign new class constructed to an existing class member?:

                You should not start learning Qt before knowing the basics of c++, sorry.

                  @Christian-Ehrlicher I've dabbled in it on and off during my college days. Figured I'd get back into it.
