+<h3>Description</h3>
+
+This is a button that when pushed pops up a menu (or hierarchy of
+menus) defined by an array of <a href="#Fl_Menu_Item"><tt>Fl_Menu_Item</tt></a>
+objects.
+
+<P><img src=menu_button.gif>
+
+<p>Normally any mouse button will pop up a menu and it is lined up
+below the button as shown in the picture.  However an <tt>Fl_Menu_Button</tt>
+may also control a pop-up menu.  This is done by setting the
+<tt>type()</tt>,
+see below.
+
+<p>The menu will also pop up in response to shortcuts indicated by
+putting a '&' character in the <tt>label()</tt>.
+
+<p>Typing the <tt>shortcut()</tt> of any of the menu items will cause
+callbacks exactly the same as when you pick the item with the mouse. 
+The '&' character in menu item names are only looked at when the menu
+is popped up, however.
+
+<P>When the user picks an item off the menu, the item's callback is
+done with the menu_button as the <tt>Fl_Widget*</tt> argument.  If the item
+does not have a callback the menu_button's callback is done instead.

+<h4><a name="Fl_Menu_Button.Fl_Menu_Button">Fl_Menu_Button::Fl_Menu_Button(int x, int y, int w, int h, const char *label = 0)</a></h4>
+
+Creates a new <tt>Fl_Menu_Button</tt> widget using the given position, size, and
+label string. The default boxtype is <tt>FL_UP_BOX</tt>.
+
+<p>The constructor sets <tt>menu()</tt> to <tt>NULL</tt>.  See <a
+href="#Fl_Menu_"><tt>Fl_Menu_</tt></a> for the methods to set or change
+the menu.
+
+<h4><a name="Fl_Menu_Button.~Fl_Menu_Button">virtual Fl_Menu_Button::~Fl_Menu_Button()</a></h4>
+
+The destructor removes the <tt>Fl_Menu_Button</tt> widget and all of its menu items.
+
+<h4><a name="Fl_Menu_Button.popup">const Fl_Menu* Fl_Menu_Button::popup()</a></h4>
+
+Act exactly as though the user clicked the button or typed the shortcut
+key.  The menu appears, it waits for the user to pick an item, and if
+they pick one it sets <tt>value()</tt> and does the callback or sets
+<tt>changed()</tt> as described above.  The menu item is returned or
+<tt>NULL<tt> if the user dismisses the menu.
+
+<h4><a name="Fl_Menu_Button.type">void Fl_Widget::type(uchar)</a></h4>
+
+If <tt>type()</tt> is zero a normal menu button is produced.  If it is
+nonzero then this is a pop-up menu.  The bits in <tt>type()</tt>
+indicate what mouse buttons pop up the menu.  For convienece the
+constants <tt>Fl_Menu_Button::POPUP1, POPUP2, POPUP3, POPUP12, POPUP13,
+POPUP23</tt>, and <tt>POPUP123</tt> are defined.
+<tt>Fl_Menu_Button::POPUP3</tt> is usually what you want.
+
+<p>A popup menu button is invisible and does not interfere with any
+events other than the mouse button specified (and any shortcuts).  The
+widget can be stretched to cover all your other widgets by putting it last
+in the hierarchy so it is "on top".  You can also make several widgets
+covering different areas for context-sensitive popup menus.
+
+<p>The popup menus appear with the cursor pointing at the previously
+selected item.  This is a <i>feature</i>.  If you don't like it, do
+<tt>value(0)</tt> after the menu items are picked to forget the current
+item.
