begin() and end() are the way to control this.
If you end() the parent window, for instance, then widgets
will be created but not attached to a parent, in which case
to attach them, you can use the appropriate Fl_Group::add(Fl_Widget*)
to parent them, which is something you should do quickly, otherwise
the widget might pop up in a window of its own.
When I want to add widgets, I usually call the parent's begin(),
then create the widget, then call the parent's end(). If I don't
want the widget to show up right away, I'd call hide() to hide it
from being shown, then later call show() to show it.
If you're trying to create a bunch of widgets that you want to
be able to re-parent from one widget to another, you should be
able to use Fl_Group::remove() and Fl_Group::add() to move the
widgets around.
Note that Fl_Window derives from Fl_Group, so the add()/remove()
methods mentioned above applies to windows too.
