<h3>Description</h3>
This widget provides a standard menubar interface. Usually you will
put this widget along the top edge of your window. The height of the
widget should be 30 for the menu titles to draw correctly with the default
font.
<p>The items on the bar and the menus they bring up are defined by a
single <a href="#Fl_Menu_Item"><tt>Fl_Menu_Item</tt></a> array. Because a
<tt>Fl_Menu_Item</tt> array defines a hierarchy, the top level menu defines the
items in the menubar, while the submenus define the pull-down menus.
Sub-sub menus and lower pop up to the right of the submenus.
<p><img src=menubar.gif>
<P>If there is an item in the top menu that is not a title of a
submenu, then it acts like a "button" in the menubar. Clicking on
it will pick it.
<P>When the user picks an item off the menu, the item's callback is
done with the menubar as the <tt>Fl_Widget*</tt> argument. If the item
does not have a callback the menubar's callback is done instead.
<p>Submenus will also pop up in response to shortcuts indicated by
putting a '&' character in the name field of the menu item. If you
put a '&' character in a top-level "button" then the shortcut picks
it. The '&' character in submenus is ignored until the menu is popped
up.
<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.
