Then they're not static members, but instance members and thus you don't
need static members. The whole point of static class members is to have
them available when there is no instance of that class.

Then static is the right choice and I don't understand your problem.

Huh? That won't work I think. You can't connect a signal just to a
function, you need an object and then it's already there.
If you want to be notified when the first instance of the tree is
created emit a signal in the function that does this.
You had some happiness once, but your parents moved away, and you had to
leave it behind.
