Matthias Melcher 49a0693962 Undid the previous Fl_Tabs::value() const change because adding 'const' *does* changed the ABI. Sigh.

<H3>Description</H3>
<P>The <TT>Fl_Tabs</TT> widget is the &quot;file card tabs&quot;
interface that allows you to put lots and lots of buttons and
switches in a panel, as popularized by many toolkits.
<P ALIGN=CENTER><IMG src="tabs.gif" ALT="Fl_Tabs widget."></P>
<P>Clicking the tab makes a child <TT>visible()</TT> by calling
<TT>show()</TT> on it, and all other children are made invisible
by calling <TT>hide()</TT> on them. Usually the children are <A
href="Fl_Group.html#Fl_Group"><TT>Fl_Group</TT></A> widgets
containing several widgets themselves.
<P>Each child makes a card, and it's <TT>label()</TT> is printed
on the card tab, including the label font and style. The
selection color of that child is used to color the tab, while
the color of the child determines the background color of the
pane.
<P>The size of the tabs is controlled by the bounding box of the
children (there should be some space between the children and
the edge of the <TT>Fl_Tabs</TT>), and the tabs may be placed
&quot;inverted&quot; on the bottom, this is determined by which
gap is larger. It is easiest to lay this out in fluid, using the
fluid browser to select each child group and resize them until
the tabs look the way you want them to.

<P>Creates a new <TT>Fl_Tabs</TT> widget using the given position, size,
and label string. The default boxtype is <TT>FL_THIN_UP_BOX</TT>.
<P>Use <A href="Fl_Group.html#Fl_Group.add"><TT>add(Fl_Widget
*)</TT></A> to add each child, which are usually
<TT>Fl_Group</TT> widgets. The children should be sized to stay
away from the top or bottom edge of the <TT>Fl_Tabs</TT> widget,
which is where the tabs will be drawn.
<H4><A name="Fl_Tabs.~Fl_Tabs">virtual Fl_Tabs::~Fl_Tabs()</A></H4>
<P>The destructor <I>also deletes all the children</I>. This
allows a whole tree to be deleted at once, without having to
keep a pointer to all the children in the user code. A kludge
has been done so the <TT>Fl_Tabs</TT> and all of it's children
can be automatic (local) variables, but you must declare the
<TT>Fl_Tabs</TT> widget <I>first</I> so that it is destroyed
last.
<H4><A name="Fl_Tabs.value">Fl_Widget* Fl_Tabs::value()
<BR>int Fl_Tabs::value(Fl_Widget*)</A></H4>
<P>Gets or sets the currently visible widget/tab.
