<H3>Creating Widget hierarchies</H3>
<P>Widgets are commonly ordered into functional groups, which
in turn may be grouped again, creating a hierarchy of widgets.
FLTK makes it easy to fill groups by automatically adding all widgets
that are created between a <tt>myGroup-&gt;begin()</tt> and
<tt>myGroup-&gt;end()</tt>. In this example, <tt>myGroup</tt>
would be the <i>current</i> group.</P>
<P>Newly created groups and their derived widgets implicitly call
<tt>begin()</tt> in the constructor, effectively adding all
subsequently created widgets to itself until <tt>end()</tt>
is called.</P>
<P>Setting the current group to <tt>NULL</tt> will stop automatic
hierarchies. New widgets can now be added manually using
<tt>Fl_Group::add(...)</tt> and <tt>Fl_Group::insert(...)</tt>.</P>
