pass "this" as parameter

Thanks for the hint which as it stands sounds chinese.
So am banned from newbie.

Are there plans for new newbies ?

Learn C++

Declare the function parameter as a base class of all Qt window classes. As you're learning C++ right now (:cool: ), I won't tell you which is it and I suggest others do the same. Find what is the base class of all Qt window classes and why does it work when you pass a pointer to the base class and then call the function with a subclass as a parameter.

Nice hint that I store carefully in a text file, however given my poor knowledge could you say the same thing in more words, in newbie terms ?
Thanks

It's as newbie as it can get. Just learn about classes, base classes (superclasses) and subclasses and look into Qt documentation and find the base class of all Qt top level windows.
