also from U++ Home page:

The most important is that Ultimate++ does not require widget objects to be allocated on the heap.

GUI toolkit just references them, it neither creates them nor destroys them.

Well, it is a bit more complicated. In fact, "internals" of widgets often reside on the heap. It is the same as this situation:

{
std::string alfa;
alfa = "Something";
}

now, where is alfa located? alfa itself in in the stack, but it might allocate some heap storage.

More complicated

struct Foo {
std::string alfa;
};

What is important is that U++ does not require you to have

struct Dialog {
Button *ok;

Dialog() { ok = new Button; }
};

This of course requires GUI just referencing thing, not deleting them....

Now you are the talented writer to describe this better Smile
