The way I like to think of it is when you create a group
widget, since the begin() is implied, it becomes a "vacuum"
that sucks in all widgets created after it, until the group's
end() is called.
So for instance:
Fl_Group *grp = new ..
// <-- all non-group widgets created here will
// <-- automatically be add()ed (become children) of Fl_Group..
grp->end();
// <-- all widgets created here will not be auto-add()ed to Fl_Group
So whenever you create a group widget, you have to be sure
to call end() if you want to turn the "vacuum" off. Or, if
you derive a class from Fl_Group that shouldn't absorb other
widgets, call end() in your ctor.
