Oh c'mon, now you are going overboard. A common way to create Widgets
is to write something like:
Fl_Box *b = new Fl_Box(10, 10, 20, 20, "My Box");
Now, "My Box" is part of the program memory and will be available
throughout the lifetime of your application anyways. No additional
work for you at all.
If you do need the label copied, all you write is this:
Fl_Box *b = new Fl_Box(10, 10, 20, 20);
b->copy_label(translate_to_german("My Box"));
and the widget will manage memory for you. There is no need to have
your label monitored at all. And your label will never "escape death
at the end of the program" simply because all memory an application
allocates is freed when the app terminates (unless you are programming
Amiga OS 1.3 and earlier).
